Valentin Mikkosovich Cassadine is a fictional character and former antagonist on the ABC soap, General Hospital. He is the son of GH's most iconic supervillain the late Helena Cassadine and Victor Cassadine, and the stepson and nephew of the late Prince Mikkos Cassadine. He is the father of Charlotte Cassadine with Lulu Spencer, who was born via surrogate.
He has been portrayed by actor James Patrick Stuart since the character's debut on July 11, 2016.
He was initially deeply feared in his family, considered to be the most dangerous Cassadine, even more so than Helena herself.
Borlenghi expressed his excitement about joining the cast, admitting that he always wanted to work on the series; "I can't imagine anywhere I'd rather be right now" he continued. The actor further stated "I don't know the extent of my stay, but I can only hope it's long enough for me to hang my shingle up and get down and dirty with Valentin."
However, the character of Valentin seemed to have been abandoned completely until 2013, when it was rumored that daytime actor Vincent Irizarry had been hired as a recast. Borlenghi took to Twitter with "Wasn't enough that I got Franco'd before? Hurts."
Soaps In Depth reported that Stuart would debut as Theo on July 8. "I get bored easily and I love a smorgasbord", the actor said. So when his agent informed him about General Hospital, Stuart couldn't turn it down.
At the time, "I was bouncing between soccer games with my children and all of a sudden" Stuart's agent contacted him about Frank Valentini's interest in him for the role. Stuart consulted with his wife who encouraged him to meet with the producers. "The role that they were talking about was so fun, it just seemed like it would be exactly the way that I would want to go back." The only catch was that Stuart had to cancel a trip to Hawaii that conflicted with taping dates.
While he was flattered to have been handpicked for the role, Stuart credits his close friends Ricky Paull Goldin and Michael E. Knight (also former co-star) with convincing him to sign on. "To have the chance to get back and do it again has been really yummy" the actor said of his return to daytime.
Stuart wrapped up his first stint as Valentin on August 12, 2016.
On October 20, 2016, Soap Opera Digest broke the news that Stuart would return to GH as Valentin. He returned on October 24, 2016.
When asked if he would commit to the series long term during his second stint, Stuart joked "Right now, [the show and I are] definitely dating."
On February 26, 2022, Stuart revealed that he has been off-screen while he films a new Disney+ series "Villains of Valley View". While he hasn’t been seen since February 10, 2022, he will return to GH in March 2022.
Borlenghi described Valentin as "morally bankrupt."
James Patrick Stuart insisted that he wouldn't have taken a role that was too "subtle." The character was presented to Stuart as "brash and take no prisoners." Stuart said Theo might have similarities to his former character Will Cortlandt. Stuart said the character has "literal crazy confidence."
Stuart said that initially, "you're struck by the fact that this guy is just being a jerk." However, "the more you play it, the more fleshed-out he becomes." Stuart declared that he had no interest in seeing Valentin become a good guy because he relished in "playing the misunderstood [bleep]hole." Valentin "is not the guy who comes in and raises an eyebrow"
The actor continued that Valentin "has much to say. He's been wronged and he needs to make sure that you understand that. He has a specific agenda!"
Valentin Cassadine was originally believed to be the previously unknown and unseen son of Mikkos Cassadine and an unknown woman. He was known for being the most evil of the Cassadine sons. According to Helena, Valentin is the most dangerous and most feared Cassadine of them all, even she was terrified of him to the point that she warned her beloved son Stavros, her hated son Stefan and her hated step-daughter Natasha to not even try to contact him.
Shortly after his birth, Valentin was disowned by Mikkos and soon became forgotten in the family, a mere myth, hence making him the most unwanted child in the Cassadine family. Valentin claims that he barely remembers his mother. He was sent to Bedlington Academy in England at the age of 5 and was left there all on his own, and was never returned to Cassadine Island. He hated the academy deeply, as it was a prison to him. He was very lonely during his childhood and he isolated himself to his books and studies, one of his many favorites was Shakespeare's writings.
During his childhood, he was unable to wear braces to help his scoliosis because he was a ward in his school and there was only money for his tuition. So his scoliosis went untreated and by the time he was a teenager, his distortion was pronounced. After graduating from the academy and thanks to his genius intellect, he found his way to Oxford where he studied linguistics. Later on, under the name Ivan Theodore, he ended up in the W.S.B. Training Academy, thanks to his brilliance in linguistics, where he was forced to train as an analyst because of his scoliosis, yet he was seen by many as the brightest trainee. During that time, he met Anna Devane, while she was training to become a field agent. He had fallen for her, and on her birthday, Valentin tried to make a move on her to which she rejected him because of his deformity. On April, it was revealed to a forgetful Anna that they had a one night stand before she betrayed him. However, it was Anna's twin, Alex Devane (disguised as Anna) that found him sad at a church drop-site, and took him to a hotel to make love – his first time. In the morning, while she was showering, he found the kill directive and ran. Valentin thought he was betrayed by the only woman who ever truly loved him.
He soon remade himself, and it was revealed on May 10, 2017, that he illegally sold a powerful bio-weapon named The Chimera Virus to his "step" mother Helena, and through this he was able to pay for his surgeries and remake himself at a special clinic in Russia.
Soon after his surgeries, he went into business with international drug lord Cassandra Pierce and later as a freelancer for Cesar Faison, in addition he had some shady dealings with Olivia Jerome during her decades of exile in Asia. Under the alias Theo Hart, he became a remarkably powerful mercenary with a vast global web of connections in different and many continents. He was charged many times for his crimes but never convicted. Becoming internationally feared in the criminal underworld, his evil "step" mother Helena, whose reputation symbolized her to be more powerful than all the other Cassadines, was also terrified of him. His former affiliation, the WSB has no record of information connected to him prior to 2011 neither under his alias nor his true name.
In November 2016, the hidden will of Mikkos Cassadine came to light and it revealed that Mikkos left all of the Cassadine Estate to the eldest living son; with Stavros and Stefan dead, Valentin is the only living son and hence sole heir to the Cassadine Empire.
On November 4, 2016, it was revealed that he has a daughter named Charlotte with Lulu Spencer, who was born via surrogate named Claudette. He loves Charlotte deeply and cares for her more than anyone. On December 9, 2016, Valentin revealed that Lulu is Charlotte's mother. He explains that Helena promised Stavros a child with Lulu, but after Helena discovered that Stavros could not father a child, she sent Daphne to seduce Valentin and recover a sample. Daphne brought Valentin's sample to Helena, and by the time Valentin figured out what had happened, the embryo had already been created, so he stole it from Helena and recruited Claudette to carry it. She gave birth to his daughter, Charlotte. However, Claudette betrayed him and took his baby away from him. After a year of enduring a custody battle against Lulu, they have agreed to a truce for Charlotte‘s sake and in October 2017, it was revealed that Valentin and Lulu currently have shared custody.
On December 20, 2016, Valentin revealed to Anna that he is fluent in speaking English, French, and Greek and during the 2017 Nurses Ball, he revealed he has a magnificent singing voice, when performing for Nina. He is close friends with Anna's long lost son with Faison, Henrik, later known as Peter August. On May 8, 2018, it's revealed that Valentin knew Henrik since he was a child. He became a father figure to him, loving and caring for him like he was his own son; he taught him how to be devious and a brilliant strategist like him. On May 23, it was revealed that after Anna gave Henrik away; Valentin tracked down the family that had adopted him and threatened them into giving him the infant, he then delivered him to his father.
On New Years Eve 2016, he married Nina Reeves. As of September 5, Nina and Valentin are still married. However, in May 2018, he and Nina became separated and she's filing for divorce again, in October of 2018. They reconciled and became engaged again throughout 2019, with two attempted weddings in November and New Years Eve of 2019.
In early 2020, it was revealed that Valentin is not Mikkos' son after all, he's actually the son of Helena Cassadine. Because of that revelation and Mikkos' codicil, it was confirmed that Valentin is not the rightful heir to the Cassadine estate and fortune which meant that Nikolas and Spencer Cassadine are the true heirs. However, on October 7, 2021, it was revealed that Mikkos' not-so-dead brother, Victor Cassadine is Valentin's father, making Valentin (and by extension, Charlotte) a true Cassadine after all.
In October 2009, a deathly ill Helena Cassadine confides in her longtime rival Luke Spencer that she needs his help to fend off her evil stepson Valentin. According to Helena, the illegitimate Valentin had been disowned by his father Mikkos upon his birth, denying him the privileges of being a Cassadine. Helena contacts Valentin hoping to use him against her rebellious grandson, Nikolas but instead, Valentin overpowers Helena taking over the family's private island in Greece and he slowly poisons Helena.
On July 11, 2016, Valentin is seen lurking around on Cassadine Island. He spies on Jason Morgan, Sam Morgan, Ava Jerome, and Nikolas Cassadine. Jason soon realizes that someone else is on the island. Valentin is seen looking at a book of Cassadine lineage before he knocks over a vase. Jason and Sam lure him out by falsely proclaiming that they are heading to bed.
They corner Valentin and he claims to be a fisherman named Theo, who was forced to come ashore due to the storm. Sam and Jason decide to leave him be, as long as he does what they say. Valentin continues to play his role and goes to warm his hands by the fire. As he is warming his hands, he rolls up his sleeve and you can see the Cassadine family crest tattooed on his forearm.
On July 16, Theo blew his cover and he held a gun on everyone present. On July 18, it was confirmed that Theo is in fact Valentin. On July 19, Valentin forces Nikolas to hand over the Cassadine family fortune to him. As Valentin tries to shoot Ava, Nikolas attacks him, but ends up getting shot and falling over a balcony.
On July 22, Ava seduced Valentin, and then hit him in the head with a book. When Laura lashed at Valentin for shooting Nikolas, Valentin went to shoot her, but Kevin stepped in the way and was shot instead. On July 26, Valentin is forced to flee after his captives get the upper hand. He escapes into the tunnels and orders his men to make sure none of them escape.
On August 2, he is seen in Port Charles meeting Nina Reeves and then has sex with her. Valentin then leaves her on August 4 in order to kidnap Spencer Cassadine, but was stopped by Sonny outside the summer camp doors, and he is then arrested by the cops. Nina and Curtis Ashford then turned in the cell phone that Valentin stole from Nikolas, which contained a voicemail of Spencer trying to get in touch with his father. While at the PCPD, he has a conversation with Nina before he was taken by the Feds.
In August 2016, Luke sent Robert Scorpio to warn his family of Valentin even though his warning was a bit late since Valentin was arrested in the murder of his nephew, Nikolas and the attempted kidnapping of Spencer. However, according to Robert, Luke wasn't convinced that Valentin was taken care of and he reminded Laura and Lulu that Luke is not known to be overly cautious and that Valentin spooks him.
On October 24, he appears on a plane as he proceeds to sit next to Claudette and stated that she took something that belongs to him. On Halloween, Valentin Reveals himself to the Spencers on Wyndemere's farewell party. He reveals to Laura and the entire group that he is the owner of the castle and the entire estate. He informs them that he plans to live in Port Charles, and hopes he can redeem himself to them.
On November 7, he reveals to Griffin and Anna that he is Charlotte's true father and he finally reunites with her after so long.
On December 5, Valentin takes Charlotte to see Santa Claus and tells him that the only thing she wants is her mom. Afterwards she meets Lulu and Rocco and Lulu feels a very deep connection to her. Valentin offers a play date for their kids in which she and Dante decline.
On December 9, 2016, Valentin confirms to the group that Lulu is Charlotte's mother. He explains that Helena promised Stavros a child with Lulu, but after Helena discovered that Stavros could not father a child, she sent Daphne to seduce Valentin and recover a sample. Daphne brought Valentin's sample to Helena, and by the time Valentin figured out what had happened, the embryo had already been created, so he stole it from Helena and recruited Claudette to carry it.
On December 29, 2016 (New Year's Eve/Day on the show) Valentin and Nina got married to strengthen his case in the upcoming custody battle over Charlotte.
In January 2017, Valentin and Nina tell Charlotte that they got married and Charlotte at first appeared emotionless on the news and then surprises Nina ecstatically on how happy that she is her stepmom. She also watches the two exchange wedding rings. Later Valentin got a call from the Canadian authorities that his plan went well.
A little while later, Valentin tells Charlotte that Claudette is dead, she mourns for the only mother she has ever known and in a few short moments she suggests that maybe Nina can be her new mommy.
On January 17, 2017, Charlotte is seen at Nathan and Maxie's wedding with her father and stepmother. Later Valentin beats up Griffin and tells him that he’s sick of his preaching. Anna bursts in, slaps Valentin and calls him a vicious thug.
At the Metro Court, Anna and Valentin face off. Andre drags Griffin away to leave them to speak. She recalls when they saw each other at the WSB years ago. She remembers his hunchback and twisted face. He claims he’s changed because of her. She insists that she didn’t care about what he looked like and they were friends. He informed her that from her rejection of him, he decided to remake himself by selling his skills to people who didn’t just exploit and ignore him. That paid for his surgery that saved his life. According to him, her rejection gave him more than her friendship ever could.
Later, Valentin finds Charlotte and she tells him Griffin says he killed her mom. Valentin says that’s a lie and vows to her that he would never harm anyone that she loved. Also she told him what Lulu told her, and he told her not to think about it for it's unimportant, and promises to explain the matter to her when she gets older and when he figures out a way to explain it properly.
On February 1, at The Floating Rib, Lulu suggests to Valentin that they can hash things out. She admits telling Charlotte she’s her mom with the best intentions. Although the sight of him makes her sick, she knows Charlotte needs him. She’s ready to take Valentin up on his previous offer of joint custody if she, Dante, Nina and he can attend family therapy together. He declines, rescinding his previous offer. Lulu’s screaming at him when Nina arrives as Lulu declares, “When it comes between wars between the Cassadines and the Spencers, the Spencers always win.” She storms off leaving Nina to admit she saw a picture of him at Anna’s. He’s sorry but Nina’s glad. Now she understands and admires him. They kiss.
On Valentines Day, Valentin gets ready at Wyndemere while on his cell with Nina who’s waiting at the Metro Court suite for him. He ends the call when Charlotte joins him. She wonders if mom’s watching from heaven. Valentin’s sure Claudette is, and then asks Charlotte for help with his tie. He shows her the engagement ring he bought Nina, and then gives her an emerald and gold bracelet. They forget the ring when they leave for the babysitter's. Valentin came back for the ring and then he had realized that Anna was at the house, he caught her off guard when she was planning to plant a bug in the living room. Anna begged him to tell her what happened in their past that made her want to put him in the WSB Kill List, but before Valentin can respond, she collapsed. Valentin rushed her to the hospital, where he stayed by her bedside and showed that his feelings towards her never faded even after all these years.
In March 2017, Valentin (and Nina) with their lawyer Nora Buchanan and Lulu (and Dante) with their lawyer Diane Miller started a custody battle with both wanting sole custody and joint custody not being on the table. The battle ended with Valentin getting sole custody and Lulu supervised visitation (one hour a week) to ensure a smooth transition for Charlotte to accepting Lulu as her mother, for it was believed through the evaluation of Charlotte done by Dr. Andre Maddox that Charlotte will be severely traumatized if she was taken from her father and put in an environment that she felt uncomfortable in. It was also mentioned that in 6 months custody will be revisited.
On March 20, Valentin stops by Anna Devane's to offer a truce and tell her that he wants to move forward with his life with Nina and Charlotte. She warns her that if she persists in coming after him, he will make her disappear for good. Anna refuses to stop digging until she knows what happened between them. Valentin accuses Anna of either lying about the cruelest thing she ever did to him, or being ashamed that she really has blocked it out. Anna gets worked up yelling and reopens the wound on her hand. When he asks about it, she reveals she has cancer and is on blood thinners. She calls it treatable, but not curable. He is sorry, but still refuses to tell her what she wants to know. He suggests she simply forget him, and walks out.
On March 22, in the Metro Court, Valentin meets the new nanny, Nelle Benson, whom Nina hired for Charlotte. When Nina took Charlotte back up to her office he made her a promise that she better not do anything to harm Charlotte or he will make sure no one will find her body. This spooks Nelle. Later Valentin meets Nora Buchanan he paid her well for her services in the custody battle and thanked her for her services and for helping him in the matter of his associate Olivia Jerome. Nora promised that Olivia would not spend a single day in jail because his associate was on her way to D'Archam Asylum and likely wouldn't see the light of day again. Valentin was pleased.
On March 28, at the hospital, it is revealed through a file on Valentin procured by Faison to be given to Anna that Valentin was accused of selling secrets to the DVX. Valentin claimed that Anna asked him for that intel, but he soon disappeared and the WSB thought he was lying to cover his tracks. Andre thinks he must have been lying because Anna wouldn't sell secrets, but she says she did. Anna explains she was young and naive, and she sold intel to the DVX. It forced her into hiding for years and she couldn’t even raise her own child. Anna doesn’t remember selling Valentin out, and wonders if someone has been lying to both of them. Anna arrives at Wyndemere and confronts Valentin with what she knows. Anna believes someone is playing them both because she never ordered him to provide her with intel. Valentin says she did, right after they had slept together.
On April 5, "Anna" begs Valentin to hear her out when she arrives at Wyndemere. She remembers everything she did to him but she was a victim too. Valentin mocks Anna’s belief that Faison manipulated her. He implores her to share something intimate she remembers of the two of them. Anna recalls finding him sad at a church drop-site and taking him to a hotel to make love – his first time. She was supposed to kill him but he found the kill directive while she was in the shower. He ran and she was relieved, giving him two hours before she called her superiors. That night meant something to both of them. Anna takes Valentin’s hands and they look into each other's eyes.
During Charlotte's first visit with Lulu, Valentin arrived to see his daughter and he is shocked as to how Lulu and Charlotte have bonded well. Later on at the Metro Court, Charlotte expresses that she misses Claudette and how confused she is about how Lulu is mother. Valentin explains that she was created in a very special way and that he and Nina will explain it to her when they get home. Charlotte also tells her papa that she had fun with Lulu but feels guilty because it's not fair to her mommy, Claudette, her papa or Nina. Valentin tells Charlotte that although he and Lulu don't get along, he wants Charlotte to form her own opinion of Lulu.
On May 10, 2017, it was revealed that he illegally sold a powerful bio-weapon named the Chimera Virus to his step-mother Helena, and through this he was able to pay for his surgeries. On May 19, it was revealed that it was Alex, Anna's identical twin sister, who Valentin slept with all those years ago and who betrayed him. She wanted to steal the Chimera Virus from him under orders of the DVX. At the same time, Charlotte was left at school by Nelle and they couldn't get a hold of her father, Valentin so they called her mother and Charlotte ended up spending the night at the Falconeri's house. The next morning the Falconeri's have a family breakfast and then Valentin shows up and apologizes to Charlotte, Later on, Dante takes her and Rocco to school.
During the 2017 Nurses Ball, Valentin sang on stage "So It Goes" a beautiful song by Billy Joel to try and win Nina's heart back, since she doubts he loves her as much as he claims. After the Nurses Ball, Valentin stayed to watch Jake's magic act, where he revealed that he has the Chimera Virus. Through the efforts of Jake's parents, Jason and Elizabeth, the Chimera was secured before it could be opened. Valentin attempted to dispose of the Chimera on his own but Anna convinced him that it's best if it was given back to the WSB. Soon after, he received a call from Nina revealing that she is being held hostage with Jason, and that the gunmen want the Chimera virus. In the end, Valentin gets shot while saving Nina's life.
At the hospital, he is well treated and taken care of, and there Anna reveals to him that the Chimera has been disposed of and regretfully reveals that she has been given orders to arrest Valentin for charges on treason, and selling the Chimera virus to Helena Cassadine. She holds his hand in sympathy, symbolizing how sorry she is. The next day, Valentin leaves the hospital in a rush, he arrives at Dante and Lulu's house to pick up Charlotte. Lulu warns him that he’s about to be arrested and urges him to make sure she has secondary custody before he leaves the country. She leaves for a moment. When she returns, Valentin and their daughter are gone. Valentin and Charlotte are in a garage. He tells her they are going somewhere special.
Valentin took Charlotte to Niagara Falls, where he planned to have him and her to "disappear". However, soon after Lulu calls Charlotte and then Dante, Lulu and Anna find Charlotte and unknowing to Charlotte, Valentin gives her up and let's Dante and Lulu take her as he was about to be arrested. Back in Port Charles, Valentin reluctantly agreed to have Charlotte live with her mother, stepfather and brother per the court as Valentin is going to prison. He was later visited by a recently escaped Alex, who has come to help him in his misfortune. She works out a deal for the two of them to be free from their crimes and seductively suggests that he finds her, once all is done. For it was she who he once loved deeply not Anna. Anna later arrives and allows him to record a farewell video for Charlotte on her phone and he promised her that she will him soon, this makes Anna skeptical. The Feds later arrive and take him away, leaving a skeptical Anna alone to wonder, if Valentin has something planned.
In July 11, Valentin returns to Port Charles. He arrives at Wyndemere Castle and sees Nina sleeping on the living room couch. Nina wakes up on the couch at Wyndemere to find Valentin standing over her. She jumps into his arms. Valentin explains the charges against him were dropped, likely because the WSB didn’t want the truth about the Chimera made public in a trial. He hoped on the first plane to return home to his wife. She points out he doesn’t have a wife anymore and suggests he go see Charlotte. She tells him that she’s at the Metro Court for Dante’s mother’s wedding. Valentin arrives at the Metro Court where he reunites with his daughter. Valentin hugs Charlotte and promises her that he will never leave her again. Lulu takes Charlotte to get some lemonade, and Valentin provides Anna and Dante with the paperwork detailing his release from the WSB. Valentin states he is free, and he’s here to take his daughter. Dante won’t let that happen, but Valentin reminds him that Lulu only has temporary custody. He tells Charlotte she should go home with Lulu and Dante for the night, because he has to get Wyndemere ready for her to come home to. Lulu and Dante leave with Charlotte, and Valentin invites Anna to have a drink with him. Valentin had a long time to think about their past and what he did, and he realized he wouldn’t have Nina or his daughter if not for her. Anna advises him not to blow this second chance.
On July 18, it was revealed that Valentin has temporary visitation.
In February, it's revealed that Valentin knows that Anna has a child with her most hated nemesis Cesar Faison. He also seems to have a close association with Henrik Faison. In May 8, 2018, it's revealed that while he was working as a freelancer for Faison, Valentin got to know Henrik as a schoolboy. He saw a lot of himself in him as he wanted the acceptance of his estranged and cruel father just like how he once wanted the same from his own father. Valentin became a father figure to Henrik; showing up for his school plays and taking him to lunch. Loving and caring for him like he was his own son, he taught him how to become devious and a brilliant strategist like him. They lost touch for many years till he contacted him for his help to free him from his father and so he could have a new life.
On May 23, Valentin revealed that after Anna gave Henrik away; he tracked down the family that had adopted him and threatened them into giving him the infant, then he delivered him to his father Faison. Nina left him because of his crimes and for being indirectly one of the reasons her brother was killed. Valentin tried to reconcile with Nina but she no longer could take any more of his secrets and lies.
In August 2019, it was revealed that there is a codicil to Mikkos' will which would prove that Valentin is not the rightful heir and that the estate really does belong to Nikolas. On October 31, it was revealed that Nikolas is alive but Valentin has no idea that he failed to kill him back in 2016. Nikolas allied himself with Jasper Jacks, one of Nina's loves, to get the will away from Valentin, but at the end of the auction for it, Ava burned it and the portrait of Helena Cassadine containing it.
On January 6, 2020, Valentin was preparing to wed Nina for the second time and threw Ava off a balcony for burning the will. Suddenly, Nikolas crashes the wedding with Ava in his hands and reveals that Valentin is supposedly not Mikkos' biological son nor a Cassadine by blood, but is actually the son of Helena and an unknown man. According to Nikolas, this was her plot to take over Mikkos' will with her illegitimate son as heir. If true, then by birth right, Nikolas is the sole current Cassadine heir, with his young son Spencer when he comes of age. On February 12, Nikolas' claims were confirmed through a DNA test between Valentin's DNA and Alexis'.
Valentin and Lulu greatly despise one another, but after realizing how their animosity between them is affecting their daughter, they began to become more civilized towards each other. Even he and Laura have started to become more civil towards one another, most likely because she can no longer hate Valentin, knowing that her son is alive and that he purposely made her believe he was dead for over 3 years, in addition she hopes Valentin would become a better man to avoid his mother's legacy.
