Well, Billie has opened the Pandora's Box of alcohol during her date with Ruth today (1/30). I'm strongly suspecting that Billie and Ruth will both be so nervous that they'll finish a bottle between them and then have a blackout. Depending on how nice Willis is feeling, what they hear about their overnight behaviour from others in the dorm will be either cutely positive or catastrophically negative.
Best case scenario is Joyce gushing: "Amazi-Girl and her two sidekicks saved you!" (Amber finds them weaving drunkenly across the quad whilst trying to make-out. She, Sal and Danny escort them back to Ruth's room and leave them on Ruth's bed, quite unconscious.)
