This is just my theory
But i think this whole arc is gonna be like hall of egress from adventure time
Where he slowly gonna grow through the mental torture that this pocket dimension give
My theory is that

She can't control someone who she sees above her
Nahyuta probably saw barem as a threat, she doesn't feel superior when facing him, instead she feels threatened
Barem probably not actually under makima's...
