lets just say any actual violence is going to provoke a response and it will not be a hinged one. hes gotta do his big boy trying to help before things get to that point or hes gonna be quickly rendered useless

im gonna avoid nightmares with him because he will try to hallucinate back at the hallucinations so there's also potential for when his idiot self can't progress more with snooping he might actually hang back and behave. by which i mean make sure """senpai""" isnt dead or maiming himself with wards.
