Keith talks to Aaron, who admits to the affair and says that it was with his agent's wife, Monica Hadwin (Emmanuelle Vaugier). Veronica frets about Duncan's diary before Veronica comes up and makes a deal with Logan: He will host another poker game so Veronica can determine who the thief is.

Sean and Weevil go off by themselves, presumably so Weevil can punish him. Keith talks to the caterer again and asks her to describe the woman she fired.
