Behind the name

Meet Ptonomy Wallace

Jeremie Harris portrays Ptonomy Wallace in Legion. FX describes him as a pragmatic presence with understated humor and the qualities of a trusted leader. That makes him a useful person to watch when the group needs to respond to a situation that is difficult to understand.

Watch how the group reaches a decision

Notice what Ptonomy treats as actionable information and what he leaves open to question. His exchanges with the others offer a way to follow a scene’s immediate purpose while its larger meaning is still uncertain.

Where to start

Begin with Legion season one, episode one, then follow seasons two and three in order. The series develops its own mystery through the episodes; use its title guide for context rather than jumping into a later season for an individual character.
