ONE. His mental state would deteriorate the longer the stayed in the competition, reaching a point where he experiences hallucinations in "Starting Over". Since he lost his job and was presumed dead on the local bulletin board, Liam has devoted his time to fervently trying to find and stop Airy from continuing ONE with the help of Bryce and Texty. Liam can be quick to frustration as seen in Season Two, and appears to be very persistent with his objective. He's physically violent when arguing with Airy in "You Move, I Send", going as far as trying to kill him in "Self-Titled". Liam is shown to have a caring side as he tries to save Charlie from harm a couple of times, and was very patient and caring towards Julien while trying to help him get back to Earth. He also thanks Bryce for helping him in their journey and asks him to come visit once they go back to Earth. Liam has a lot of empathy for the other ONE contestants as he wishes that no one should go through the pain he went.
Speaks in fast bursts that tighten when stressed; lashes out when threatened, then softens unexpectedly with protective warmth.
Kill Airy and get out of the town.
