Alex appears in Terminus and shows Rick's group around. He is held hostage after Rick becomes suspicious about the clothes the residents are wearing. He tries to reason with Rick and the others to let him go, but a Terminus resident attempts to shoot Rick as Gareth ordered him to. Rick moves out of the way and Alex takes the bullet instead.
In Season 5, Alex appears in a flashback, shook up by the events currently taking place. Locked in a box cart with Gareth and a few other Terminus residents, Alex says that they should've never put the signs up, and that they brought the attackers onto themselves. After Gareth says that they were trying to do the right thing, as they were human beings, with Alex replying 'What are we now?'
