"My roommates and I have been looking for a fourth for Spades."
So, let me see... Katie throws Derek out of their cabin and then wanders up to the designated smoking area on deck 5, port side, where she sees Derek and Entertainer Esme (and nobody else) kissing. In tears, she runs all the way back to their cabin and locks out Derek who has followed her all that way without catching her. Then Derek, with his marital relationship at risk, hikes back to the designated smoking area where Entertainer Esme is smoking another cigarette, holds her, calls her "Beauty," and uses a metaphor of doomed romance, which Entertainer Esme quickly turns sexual.
Being good looking sure comes with a lot of stupidity.
