Back at HQ, Mr. Sobell is singing a happy tune -- "More scenes with Gwen! More scenes with Gwen!" -- and Cavaliere is asking Gwen what she knows about Paul's schedule. He had cut down on clients so he could train more aggressively for the Mr. Las Vegas competition next month. Gwen notes forlornly, "He really wanted to win this time. He cancelled my last two workouts." Cavaliere's all, "You know, there are other cops -- I mean, trainers in the sea. Also, have you checked out these guns? Police-issued, baby." Gwen's all, "Yeah, I was thinking about ditching him. Especially after I made a pass at him a few sessions ago and he shot me down because he had a headache." "Perhaps he was gay," suggests Cavaliere, and Gwen's all, "I don't care! Just lying back on that bench, sweating and pushing the weight with all of his muscle right beside me. I mean, it was totally...motivating." Cavaliere is seconds away from suggesting that Gwen check out the weight bench in the police locker room. You can see it in his eyes.

Liam and Sara are processing the scene, and Liam is getting all philosophical with, "No matter how hard you work to get big, there's always someone bigger." Sara comments, "It could be what keeps them going. Like Freud said, 'Anatomy is destiny.'" Liam would like to know if Freud had any non-contextual quips validating Liam's theory that the murder weapon is one of the weightlifting bars. No, but Sara's going along with the hypothesis anyway. She natters on, "The killer didn't even have to be the same size. All they needed was the right weapon, some leverage, the element of surprise…" Liam is ignoring her in favor of flexing in front of the mirror.

Cut to David the Droll Coroner telling Emergency Backup David, "Victim is a well-developed male. Musculature appears hypertrophied." I love his gift for understatement. He then asks Emergency Backup David if he'd like to guess on the COD. Emergency Backup David suggests, "Blunt force trauma," and David twinkles, "Absence of bruising." Emergency Backup David recovers: "Maybe it was a post-mortem blow." The two prepare to find out.
