I just rewatched The Force Awakens last night. Ben 100% has a one-sided conversation with Vader's helmet where he was asking for advice.What doesn't make sense (if Palpatine was in Ben's head since he was a boy):
Why didn't we ever see Anakin speak to Ben in the films?
Is this going to be another thing that the novels will fix? lol.
It might be a retcon, but it works cause they accidentally set up for it.
