Trevor Holden (Traveler 0115), played by starring cast member Jared Abrahamson is a member of the show's core Traveler Team and the team's Engineer. The host body is a high school student — a jock and quarterback of his school's football team — who was dating Rene Bellamy.
As a result of testing the conscious transfer tech and having had several host bodies, Trevor is one of the oldest people in recorded history. He is often referred to as an old soul and has often been shown to enjoy meditating, especially when he's stressed or needs to clear his mind.
Trevor was to have been beaten to death in an illegal, underground cage fight. After the consciousness transfer happened, the traveler was able to concede the fight.
0115 Future History
Traveler 0115 is the oldest member of the team (despite being in the youngest body) as he was part of the team who began experimenting with consciousness transfer. His actual age is unspecified, though he says he has lived in “many bodies” and tells Philip that he's been in bodies so old that one fall would cause bones to break.
After Grant MacLaren's unborn baby had died, Trevor mentioned that he had had two sons who had died of old age before his arrival in the 21st century.
When talking to Grace, Trevor mentions that he lived with a woman in the future and they raised children together in three different lifetimes. He said that it didn't matter about their age difference of their different hosts, just that they were together. He says that they were soulmates, but that she unfortunately developed Temporal Aphasia, causing her to effectively black out for minutes or hours at a time. This was caused by living in multiple hosts and was completely incurable. She said she wanted to see the sun one last time before she died and so Trevor took her to one of the shelters which hadn't been fully build so the sun was still shining through the ceiling gaps. There, she blacked out and never came back. (Trevor)
Before Traveler 0115's consciousness was transferred into Trevor's mind, Trevor was a notorious bully and the star quarterback of his high school's football team. Trevor's grades were lacking and didn't seem to be much of a priority to him, as, according to his father, he was hoping for a football scholarship.
Early in the first season, it is revealed that Trevor ran a shoplifting operation with his girlfriend and his friend Nick. He also took prescription drugs which Nick often stole from Trevor's mother. Trevor often took part in illegal underground cage fights, which would have killed him if it hadn't been for Traveler 0115 calling off the fight after the consciousness transfer.
In season 2, it is also revealed that Trevor, along with his friend Kyle and many other unnamed boys, had been sexually abused by their football coach, Carson Perry which lead to Kyle quitting the team and assuming that Trevor did for the same reason.
Traveler 0115 conceded the fight which would've killed his host, saving his body.
He met his host's parents early the next morning (as they pointed out that he was up surprisingly early). His father, Gary, lectured him on how stupid it was for him to have gone to the underground cage fight, mainly because it could ruin his chances in football while his mother worried about him. They were both surprised at how polite he was.
He later meets his girlfriend, Rene, who is worried about him and then takes him inside with the intention of having sex with him, but Trevor wasn't interested in that. He lied to her, and later to his friend Kyle, telling her that the concussion made him forget things and possibly cause personality changes and that he needed help remembering them.
He goes to the abandoned building to meet his team in the night and saves Grant from falling down the elevator shaft. He provides the countdown to consciousness transfer while the rest of the team explain what they are. He also prevents Joans Walker's shooting rampage by killing him. (Travelers)
When the team cannot hand over the antimatter container after the team leader dies, Trevor thinks he knows how to make the container last longer. However, his plan backfires and ends up cutting the time into only a couple of hours, so the team have no option but to return the antimatter to Deleney's lab. (Protocol 6)When Trevor finds out about host Trevor and Kyle's abuse by their football coach, Traveler 0115 makes it his mission, as part of his protocol 5, to expose Carson Perry years before he was historically exposed. He said that he wanted to do this because as far as he was concerned, it was Coach Perry who killed Kyle by leading him to drinking as a coping mechanism. He later reveals Coach Perry's abuse. (Update)
Traveler 0115 began to suffer from Early Onset Temporal Aphasia not long after his consciousness was overwritten in order to replace the AI messenger program which was taking over his brain. He explained that it was a side effect from living in so many host bodies, something which only one other person suffered from ever (his late wife) and that he knew he was going to die from it eventually and that he was letting the Director overwrite him because the host was still healthy. The rest of the team and Grace disagreed, so made an implant to stop the black outs caused by the Temporal Aphasia without the Director's consent. Trevor was furious that the team did this behind his back, turning on all the cameras so the Director could overwrite him but he didn't -the team suggest because the Director changed its mind but Trevor thinks the implant compromised the host. (Trevor)
- He often refers to himself as an 'old soul' in reference to how many lives he's lived.
- He says he makes a 'mean veggie stir fry' which he then makes for the team in Ilsa. The rest of the team refuses to eat it, but Trevor and Wakefield happy eat it. When Wakefield asks what spices are in it, Grant says 'all of them'.
- When talking about temporal (displacement) aphasia, Trevor says that that there was only one other case of it and says that 'he (the first sufferer) was a previous record holder for the longest living human'. He later refers to the only suffer as his wife.
Trevor: What about me?
Philip: You are too young to gamble.
Trevor: An excellent example of irony.
