LMFAOOO perfect... jae-ha is a good boy who will try not to fight mephisto back if he knows he's being controlled, but if he comes at him full force he'll have no choice!! I'm thinking it can be like they find the npc but he uses controlling mephisto as a distraction and hides, so jae-ha has to deal with finding npc-chan to stop the source and so has to fight mephisto for a while/hard enough to knock him down long enough that he can find the npc.
