What do Q and Lacey talk about in the bathroom?

Later at the party, Q retreats to the bathroom. Lacey is fully clothed in the tub and asks him to talk to her. He agrees and tells him that she and Becca fought. Becca had destroyed Lacey's reputation by telling everyone she had had an STD. Lacey says that Becca is the "new Margo" and that everything sucks without her. Q continues the conversation until Lacey falls asleep.
