Cut to Gil noting the bloodstain on the side of the Cunninghams' spa and explaining to the couple that they've matched the water in Vanessa's lungs to the spa. Mrs. Cunningham figures her neighbors did a little pool-hopping. She also gives them a snow job about her and the mister leaving the party for a night at the Bellagio because "sometimes, being with others gives you the urge to be alone." Gil points out that he'd like to know if Mr. Cunningham was alone with Vanessa Keaton. Surprise, surprise, he was. And with Erin Brady -- or Karen Brady, as she's called here. And with someone named Mallory Stone. Brass quips, "Three strikes, you're out." Mr. Cunningham grins.
Back in the B-plot, David's puttering around the morgue when Warrick comes in. "Heard your suspect's looking pretty good," David says. "You heard right," Warrick chirps. He's all hepped up because not only did Charlie confess to killing his landlord, the blood on Charlie's watch matches his finely-filleted former landlord. But Charlie's still insisting he didn't kill his girlfriend and stuff her in a Ms. Pac-Man machine. The two of them engage in some dialogue about what could have possibly caused the rounded, blunt-force wound to Melissa's head, in an effort to flout the 48-minute rule. Fools, I say! Everything means something after the 48-minute mark.
Even this conversation with Mrs. Cunningham, wherein we discover that she did not actually have the urge to run off and be alone with her husband at the Bellagio. She had the urge to run off and be alone with another woman, which so offended Tom Cunningham's sensibilities, he went to the "what about the children?" argument and browbeat Marion here into saying they were together. She adds, "I swear, I don't know anything about what went on between him and Vanessa. I don't know."
