Background[]
He is a friend of Dr. Lucas Jones from med school.
It was also revealed that he is the previously unknown son of Duke Lavery, who was conceived before Duke met Anna Devane. Griffin also stated that he didn't know who his father was until after his mother, Margaret Munro passed away (she wrote him a letter explaining everything).
He has also formed a friendship with Anna Devane.
As of April 15, 2016, it appears he also recognizes Det. Nathan West. On June 29, it was revealed that Griffin had an affair with Nathan's then-wife, Claudette and Nathan shot him in a drunken rage. On August 3-4, Claudette and Griffin unexpectedly reunited with each other at General Hospital. It was also revealed that Claudette was and is still in love with Griffin and he is in love with her at the time.
Storylines[]
Dr. Griffin Munro first arrived in Port Charles in February 2016, having taken over the neurosurgery position vacated by Patrick Drake. After encountering Sonny Corinthos in the hospital chapel, he is soon assigned to become his doctor and discovers that Corinthos has been faking his paralysis for some time. After imploring Corinthos to come clean to his loved ones, Sonny tells Griffin that he needs for his enemies to see him as weak. Griffin agrees to Sonny's request under the condition that Sonny keep him up to date on his progress.
Following the accidental shooting of Kiki Jerome, the truth about Sonny's health comes to light, and Griffin ends up apologizing to Sonny's wife, Carly Corinthos for concealing the truth. Griffin is also tasked with informing Kiki's mother, Ava Jerome and Franco that Kiki may have limited mobility as the result of her shooting. Griffin is also introduced to Anna Devane by Lucas Jones, and it becomes apparent that Griffin shares a mysterious connection with Anna. Griffin is also on hand to treat Tracy Quartermaine after she suffers a seizure at The Floating Rib.
Griffin and Claudette kiss
On March 15, 2016, Griffin revealed to Anna that he's Duke's son and he has since taken a DNA test that proved that he is Duke's son.
On May 24, 2016, he walked Maxie Jones down the red carpet and received a text from Emma Scorpio-Drake prior to the Nurse's ball.
Later in 2016, it was revealed that Dr. Munro is no longer a suspect in the deaths of patients at the hospital.
Griffin assaulted by Valentin
He is also eventually revealed to be the man that Nathan's ex wife Claudette cheated on him with and that Nathan shot. On January 19, 2017, during Nathan and Maxie's wedding, Griffin gets a beat down from Valentin after he declaring he doesn't deserve his daughter Charlotte before being saved by Anna.
In March 2017, Griffin was kidnapped by his fathers thought to be dead ex-girlfriend, Olivia Jerome, who was obsessed with him. She tried to use Griffin to resurrect his father.
In late 2017, Griffin gets involved with Ava Jerome and eventually ends his relationship with the church (as a priest) to pursuit a relationship with her. In 2018, when Ava threatens to have Sonny's alzheimer father Mike Corbin arrested for unintentionally kidnapping Avery, Griffin begins to see see her in a different perspective and on May 7, he moves out of her apartment and moves into the Metro Court. Despite seeing him as the worst kind of hypocrite, Carly reluctantly allows him to stay at the hotel because she doesn't want him to go back to Ava.
On May 23, 2018, after the Nurses Ball, he and Kiki Jerome end up drunk and then soon end up having sex. The next morning, they agreed to keep their night a secret so they wouldn't hurt Ava.
On August 13, 2018, Griffin confessed during court while under oath, (during Kiki's harassment case), that he had slept with Kiki. In the aftermath of this revelation, Griffin moves into Kiki's building, and they start a relationship - all while her mother plots revenge (Including manipulating the Church to impose a punishment on him).
In September, Griffin has to move into the studio at Kiki's apartment after Ava got him fired from GH. When the heat breaks, he and Kiki find themselves hot, sweaty, and scantily clad in her apartment. They grow closer, share stories about films and their annoyance over Ava, and their attraction grows deeper.
On October 4, Kiki runs into Griffin at the gym. She admits that she wanted to sleep with him the night of the Ball, and that she still wants to be with him. He wants the same, and the kiss, beginning a new relationship. They agree they want something more than revenge against Ava or uncontrollable lust - but rather something they could make last. They agree to a first real date at the upcoming Port Charles Film Festival at the Metro Court.
On October 16, after attending the festival, they go back to Kiki's apartment where they watch a musical, then make love.
On November 9, after studying and making love, Kiki witnesses Sasha hit on a dumbfounded Griffin; leaving the couple disturbed.
Sasha is later seen at The Metro Court and she confronts Ava and tells her off. She then orders soup up to her room. Ava sees the soup and puts the sleeping pills she just got from "Kevin" to drug Sasha. Ava goes up to her room and goes it to find Sasha passed out. She takes off her clothes and puts her in the bed. She takes her phone and texts griffin telling him that her and Kiki are working things out and to come to the hotel.
Griffin shows up and Ava hits him over the head with a vase. He gets knocked out and she takes off his clothes and puts him in the bed with Sasha to make it look they slept together. Ava leaves and she calls Franco telling him that she saw Sasha and Griffin go into a hotel together. She tells Franco he needs to say something to her because Kiki wont believe her. Franco tells Kiki and she goes to the hotel and sees them together. She gets mad and leaves. Griffin is able to see that Sasha was drugged and he goes and tells Kiki. She and Griffin quickly realize Ava set it up in revenge.
On November 26, while getting ready for Curtis and Jordan's wedding, they discuss Ava's extreme revenge strategy, then make love on Kiki's couch. Monica calls Griffin, telling him the GH board has made a decision about his suspension, asking him to come to the hospital and sign the paperwork. They kiss, he leaves, and Ryan Chamberlain shows up shortly after, and murders Kiki.
Griffin & Kiki - Last kiss before dying
On November 27, 2018, after Kiki is murdered, Griffin is blamed for her death and was placed under arrest for her murder. Ava tried to shoot Griffin dead at the station on December 3, but she was stopped by "Kevin" and Julian, who had wanted to beat a confession out of Griffin earlier that week. Griffin was released on December 6 after the PCPD suspected that the same person killed both Kiki and Mary Pat Ingles, who was killed on Halloween similar to how Kiki was. The person who killed both women then killed film producer Peyton Mills on New Year's Eve and attacked Lulu in late January 2019 before framing Franco for the crimes. That person was serial killer Ryan Chamberlain, who had been presumed dead for 23 years and for months, was impersonating Kevin, whom he had locked up in Ferncliff. Ryan was presumed dead on March 8 after tossing himself off a bridge to evade capture.
On March 22, 2019, after beating up Kevin, he tries to kill him for knowing that Ryan was alive, but is stopped by Ava. After getting his bruised hands treated by Lucas, Griffin decides to leave town and grieve Kiki on his own by quitting his job at General Hospital.
On December 6, Griffin returned to Port Charles to check on Lucas, who was rendered comatose at GH following an accident. He tells Sonny and Carly that his in a "wait and see" condition before discussing about Mike with Sonny. Griffin says that the lab results show that Mike is severely deteriorating, but mentions a study which he believes Mike would not qualify for. Sonny then tells him that he has the means and that he should try to get Mike in the study.
On December 9, Griffin reunited with Ava at her gallery and then with Anna the next day at the Metro Court. Griffin also saw Maxie and Laura again and found out about Lulu and Dante's divorce due to Dante's PTSD. Before leaving town again, Griffin met Jasper Jacks and helped explain the story of Claudette and Charlotte to him, noting that he doesn't believe that the former's death is a suicide.

On November 30, 2020, Nikolas says that Patrick and Griffin were told about and confirmed Lulu's brain diagnosis which put her in a coma.
