In The Scorch Trials Tim made it to the Phase Two along with 19 other Gladers after escaping The Maze. He disappeared during the lightning storm that occurred in The Scorch, alongside six others, including Jack, Stan and Winston. Although his fate is not definitely known, it is quite likely that he died in the storm.
In the Maze Runner film, Tim is present as one of the Gladers. He accompanies Thomas on his attempt to get out of the Maze and is one to survive alongside Thomas, Teresa, Newt, Minho, Frypan, Winston, Jack and Billy.
In the Scorch Trials film, Tim is shown with the main group in the WCKD facility. He is also seen in the lab in the WCKD facility behind Minho. Later Janson calls the name Tim for testing. He is not shown escaping with the others, as he was shot in the back by one of the guards.
