Okay, Legion tag, listen up. Possible Spoiler.
Some of you are a little confused, so here’s some background: David, a.k.a Professor X’s son and an Omega-Level Mutant, has powers that manifest with his split personalities. At the end of the first episode when he’s on the beach, some of those people are not real, some are his personalities. This show is about to be a ride as we try to figure out who is real and who is actually David. That’s what makes him so powerful; with each personality that manifests, so does a new power.
