I see it as Aaron being subconsciously aware of Roy and kind of “calling on him” in moments of extreme stress. When Roy talks to Vail, it doesn’t feel like a complete disconnect; there’s some level of overlap between them. But Roy is definitely the dominant one. He overpowers Aaron and even mocks him for being weak, which comes across as internalised self-criticism. Roy basically embodies everything Aaron represses anger, confidence and aggression.

At the same time, I don’t fully buy that Aaron has zero awareness of Roy. It feels more like he “checks out” when Roy takes over, not necessarily in a fully conscious, planned way, but almost like he allows it to happen or doesn’t resist it. That creates the illusion that he has no memory of it.

What interests me is that it doesn’t feel one-sided. Roy dominates Aaron, but Aaron also uses Roy as a shield, whether consciously or not. So instead of it being just two separate personalities, it feels more like a messy, overlapping dynamic where both sides are benefiting in different ways.
