Actor Mark Pinter joined the cast of GH as Agent Tom Rayner on December 11, 2008. He recurred on the show until June 5, 2009.
On January 7, 2010, it was announced that Pinter would return to GH as Agent Rayner. He returned from January 26 to February 17, 2010.
On December 11, 2008, Special Agent Tom Rayner first appeared when he asked Jason Morgan and Sam McCall to give their side of the story on the Russian case. Jason and Sam told their side of the story and Rayner decided to close the case since they were acting in defense of a minor child.
On December 15, Rayner appeared again when he showed up at Jason's penthouse to offer Jason immunity from prosecution in exchange for information to build a case against Sonny Corinthos and Anthony Zacchara.
On January 12, 2009, Damian Spinelli was arrested since he violated the Homeland Act and Rayner made a deal with Jason. If Jason provided the information on Anthony and Sonny, then Spinelli would not have to go to prison. Rayner added that Jason was more useful to the F.B.I. than an undercover informant because he could get into places they could not get into due to the laws the Agents have to abide by. After some reluctance, Jason agreed to Rayner's deal and before Spinelli could be transported to federal prison, Rayner told them to let him go. Spinelli's continued freedom was contingent on Jason's success.
On January 14, Rayner ordered Jason to help the F.B.I. find a truck full of cargo from the Equinox Defense analysis & construction corporation that was hijacked. In February, bio-toxins were released in the hospital so the F.B.I. ordered it to be in lockdown as to not poison anyone else on the outside. Eventually, the hospital started catching on fire and Trevor Lansing stole the last bio-toxin. Sam tried to talk Trevor down and she eventually threatened to shoot him even though she didn't want to. Sam and Trevor fell of the roof but Jason saved her and they recovered the bio-toxin before destroying it in a fire. Anthony Zacchara eventually disappeared which made Rayner angry. Rayner made it clear that unless Anthony is found alive then Spinelli would spend the rest of his life in Federal prison. Jason and Sam managed to track him down to a resort he was at but they were too late since Anthony went back to Port Charles. Jason worked with Sonny to find Anthony since he kidnapped his daughter, Claudia. Jason took Anthony down as Sonny rescued Claudia. After Rayner showed up and arrested Anthony, Jason said they were done but Rayner said that he now wants Jason to get information on Sonny. Afterwards, Jason planned to get Spinelli out of the country since he didn't want to take Sonny down for the FBI but Spinelli left on his own to California. Jason, Sam, Maxie Jones and Agent Winifred Leeds managed to track him down. Jason still wanted to get Spinelli out of the country but they eventually decided to go back to Port Charles and delete the evidence the FBI has on Spinelli.
On March 17, Rayner showed up at Jason's penthouse to look for Spinelli. He issued a warrant for Spinelli's arrest, deemed him "armed and dangerous" and he blackmailed Jason into wearing a wire to Sonny's house where they were announcing that Sonny's taking over the Corinthos organization again. Rayner wanted Jason to get Sonny to say something incriminating but Jason tipped Sonny off and they were talking about coffee which angered Rayner. Eventually, Rayner threatened to put both Jason and Spinelli in federal prison for life, but was forced to let them go free when all the evidence against Spinelli had been deleted completely. Rayner promised he would not back off of them.
On May 27, Rayner was seen again when Alexis Davis hired him to do a thorough background check on Rebecca Shaw. Rayner exchanged a date with Alexis for an F.B.I. profile on Rebecca. After hearing her case, he then decided to get her what she needed on Rebecca after Alexis said that she looked exactly like Emily Quartermaine and that her nephew, Nikolas Cassadine has a lot of money.
On June 5, Rayner met with Alexis again and he provided her with the file on Rebecca, though he warned her that it may be the opposite of what she wanted to see. Alexis looked at the file and was shocked to see that Rebecca was Emily's identical twin sister. After debating with Rayner on whether to tell Nikolas the truth or not, Alexis decided to and she revealed the truth to Nikolas.
On January 26, 2010, it was revealed that Rayner was the one who tasked Detective Dante Falconeri from the N.Y.P.D. with the mission to infiltrate Sonny's organization so he can take Sonny down. Dante's mother, Olivia Falconeri revealed to Rayner that Sonny is Dante's dad and attempted to blackmail him into taking Dante off the case by threatening to reveal Sonny and Dante's connection as father and son if he didn't. Rayner called Dante anyways and informed him that the timetable has been moved up so Dante can arrest Sonny on Friday, January 29. Dante tried to arrest Sonny, who shot him in the chest at point blank range. When Olivia came in screaming that Sonny just shot his own son, Sonny and Olivia rushed Dante to the hospital in order to save his life. After Dante pulled through surgery, Detective Lucky Spencer from the P.C.P.D. took his statement, where Dante lied and claimed that he accidentally shot himself in the chest after Sonny's gun jammed when he tried to unload it.
On February 11, as Dante was recovering, Rayner paid him a visit and accused him of lying in his statement. When Dante stood by his original statement of how he got shot, Rayner revealed that the N.Y.P.D. Internal Affairs left Dante's fate to his discretion - he gave Dante the opportunity to resign and threatened to fire him from the N.Y.P.D. if he refused. However, P.C.P.D. Commissioner Mac Scorpio later came by Dante's room and offered him a job at the P.C.P.D., which Dante accepted.
On February 17, Rayner paid Dante another visit and demanded him to testify in court against Sonny, even if it means he had to be wheeled into court on a hospital bed. When Rayner got in Dante's face and warned him not to pull another stunt before threatening him, Olivia came in and threatened Rayner herself as she stood up for Dante. Rayner in turn revealed that Olivia is set to be taking the stand herself to testify on the witness stand and he suggested that maybe she knew some things about Claudia Zacchara's death but Dante brushed him off by saying she had nothing to do with that and Rayner knows it. Rayner warned Olivia to tell the truth or else she will be in a world of trouble before leaving and slamming the door behind him.
