Deses said: As shown in ep7, soul gems block out intense pain. So Mami just felt the psychological pain. That is, if she didn't faint.
Ahh okay, I must have misremembered.
I thought that all the soul gem did was keep its owner alive, even if her body was destroyed. If the whole "blocking out intense pain" part was in there then I totally forgot about it. Does kind of ring a bell though.
Gonna have to go back and rewatch the old episodes before the new ones air.
