a little bit of a dumb idea but i got an idea for another possible confession.
stare
your silence will say everything (you start out as a high security inmate)
the memory of that crime was repressed for a reason. the truth may never fully reveal itself, and it certainly won't here. your expression gives jake all he needs to know, and he even looks a little scared.
he quickly cuffs you, and leaves the room silently.
