Since he saw the inquisitor got taken over in the past, my guess is that he try to get the butler to take over, then get killed, leaving only the MC in the body. The gamble is probably if the butler stay dead or if the MC can be reviveno clue what the plan is here
one of the reasons I am still on board even though I hate this ship.Its got to be something he can only find out by reading the butler's bio but I'm not sure what that could be. The butler's goal is the win condition? The answers to these puzzles have been fun in past chapters so I'm looking forward to this one.
