Will and Chewy question the perp about the details of the murder. He seems to be giving all the right answers, from the looks the cops are giving each other. The perp's an okay actor, but I wasn't buying this storyline from the first second he walked into the station, and neither were most of you, so let's move on.

Luke's in the kitchen making a big-ass sandwich while Joan bones up on law. "Did you know that if you admit that you did something, it's less of a crime than if you deny it?" Luke mutters, "I didn't know it was the last piece of cheese. Kill me." Joan: "Interesting. A guilty conscience always rises to the surface. I was actually talking about Mock Trial." Luke enthusiastically slaps layers of bread and meat together and squirts mustard around. She asks, "What is that?" He tells her it's a Dagwood, and then, for the benefit of all the viewers under the age of fifty, I suppose, explains its origins. He blathers on as Joan says dismissively, "Grace was right. Some things just should not be remembered." Luke studies the contents of the fridge for a food group not already represented in his sandwich. Joan: "When you're done inhaling the entire deli section, I'm gonna need your geek services in compiling some data." He tells her he's serving as legal advisor to the defense. Joan: "You're helping Grace? What happened to 'blood is thicker than water'?" Luke: "Got trumped by make-out sessions in the biology closet." Those two really need to branch out and find some new sites. Joan scoffs that he'll be on the losing team: "Jack is totally guilty. The only question is, can I up the charges? Murder in the commission of a felony carries LWoP -- life without parole." LWoP? Shout-out, of sorts? I'll tell you, it's starting to feel like Television Without Parole over here. Luke sits down next to Joan with his giant sandwich and inquires, "Don't you think it's weird that you're prosecuting your boyfriend?" Joan: "Can it, Sigmund." Luke thinks it sounds like a "classic case of playing out feelings of resentment and aggression." Joan snaps, "Things are fine! It's our anniversary." Luke: "Yeah, but…I know how weird it was when you two…went away for the night." Really? How does he know about that, exactly? She replies, "I don't think you should be the one hosting Loveline. Your love life consists of making out next to jars of pickled frogs! Adam and I are fine." Luke picks up his sandwich and attempts to bite into it, managing perhaps the middle third. Joan grabs the top piece of bread, licks the underside, and slaps it back on his sandwich, smushing it down for good measure. Luke doesn't react much as she marches upstairs.
