“Really? They didn’t continue with Sam’s psychic thing? I thought he still had psychic connections to the other “special” children in later episodes…some of them? I guess I’ll find out I was remembering wrong as we watch.”
I was talking specifically about telekinesis — when he moved the armoire out of the way to save Dean. We never see Sam with telekinetic powers again, as far as I know. It sort of felt like the writers wanted to go there initially, but decided against it. Like PNP said above, maybe they didn’t want to make Sam too super-hero-y with his abilities.
