s01e08 “Bad Blood”
The Sinners concoct a dumb, pointless plan to gather up a bunch of bloody cotton balls from the school Blood Drive, so they can test them en masse to see if one of the students is the father of Imogen’s rape baby. Oh, and Crazy Joe comes back, acts super threatening, seems to clearly be A and then k-words himself, so of course he’s not A. Help.
