re: Legion Season 1 Thread - Starts Wednesday 9 CT on FX

Would somebody mind explaining the significance of the drooling guy? They show him drooling in two separate hospital scenes. One in the first episode and one when the whole team goes. Maybe they were different people. Anyway, then when Melanie is trying to change the frozen bodies around, she finds him alone, bleeding. She whispers something in his ear. Next time I remember seeing him, he has the power to tackle Lenny/shadow king away from Sydney and Kerry. I say he has the power because Lenny just got done crushing a powerful mutant with her mind. So, tackling her has more to it than that. Are there parts where his significance is explained and I missed it? He just seemed kind of random. Also, if he was the same drooling guy in both scenes, it's weird he would be in the psych ward in the beginning. Maybe he was there keeping an eye on David.
