a character cuts his arm in order to use the blood to pretend he has had sex on his wedding night and also someone's arm gets cut on purpose so they can pretend to the police that they were rushing to the hospital rather than picking up drugs and running away
there is a priest in s1 who self-flagellates several times with a whip and there is an instant of someone cutting themself on purpose to stain their bed with blood so it isn't for the purpose of harming themself
