Legion (Season 3)
"Open your third eye."
David Haller, AKA Legion, is a troubled young man who may be more than human. Diagnosed as schizophrenic, David has been in and out of psychiatric hospitals for years. But after a strange encounter with a fellow patient, he’s confronted with the possibility that the voices he hears and the visions he sees might be real.
The final season — David uses a time-traveler to try to rewrite his past. The surreal Fox X-Men show reaches its conclusion.
