Well Sister finally knows where she is, and Brother thinks she's too negative. Their mom makes a brief appearance before Allison realizes Jon is trying to crap on her when she can't hear him.
Jon names his favourite cousin, Allison recounts her trip to Newfoundland (including when Mary Walsh called her out in front of her crush), and they both admit they wouldn't do well in jail. But would Brother help Sister hide a body?
Important reminder: Don't forget to fart
