Ways to cast from pawn to character / Controlling the character from another BP

Ive been doing some searching for the last hours or so on this subject, maybe im using the wrong keywords but ive been trying a lot of different ones.

What im trying to do is have a master controller pawn that i can use as the Camera and be the main possessed actor, and trough that, control my Character

ive been trying to cast to it from the actor blueprint but it doesn’t seem to go the way that i want, any ideas or other thoughts ?

Another question is where do i put the movement blueprint graph, is it inside the character BP or the Actor BP depending on who im possesing ?Actor BP
