I think the ghost was his feelings over flowing or maybe the loss of his feelings?? Idk
Yeah I think we’re being duped by the term “ghost” but there probably is a reason only him can see it anyway must be his feelings towards agaraki as you said.
Maybe they are both schizophrenic in a weird universe in their brains that make em both imagine it .
Couple goals
Real
the ghost is just his lost memory, so it's basically just him
SAY WHAT????
Huh .
Assumption one : he lost his memory when he fell. But then why is he a ghost when he’s alive ??
Assumption two : shit I don’t know. Why is he a ghost??
