Sean confronted his mother. She was making him relive his childhood horror of walking in on her passed out. He didn't want Trey to have to go through the same. They struggled over a bottle of liquor. When it crashed to the floor, AJ, Caitlin, and Cathy all ran in from outside. They were then witnesses to Sean calling his mother a drunk and her slapping him. Olivia's response to the presence of witnesses was simply to wonder who had invited them in. She stumbled around the room and accidentally knocked Cathy's purse to the floor. Caitlin introduced Cathy as a friend of hers.
