...who indeed agrees to go to O'Donnell's, which is hopping. Bossy and Lynette haven't even sat down yet when Bossy spots some ripe fruit of a man sitting at the end of the bar. She says to Lynette: "Get him for me." Poor Lynette!

Betty sits at the kitchen table. She's wearing rubber cleaning gloves and writing something on a sheet of paper. A timer goes off, and she takes off the gloves and prepares Basement Buddy's tray and takes it down to the dungeon. Basement Buddy is sitting there on the bed, un-manacled, and Betty doesn't even have her gun, or son, with her or anything. Huh? Buddy starts to eat, and she starts changing his bedding. Casually, she mentions that they're "going on about Melanie Foster on the news." He stops chewing. Betty: "It's time we talked about it, Caleb." Basement Buddy's name is Caleb! Betty tells Caleb that until he "accepts responsibility for what happened," she can't let him out of the dungeon. Upstairs, strapping Matthew -- who is wearing a very well-fitted wife-beater tank-top -- reads over what Betty was writing: it's a letter in all block letters. It reads: "To the Chicago Police Dept, I know who really killed Melanie Foster. You have arrested the wrong man." Matthew, yelling: "What the hell is this, Ma? Where are you?" Betty tells Caleb that she'll be right back, at which time she will expect some answers out of him. She rushes out of the dungeon, yelling to Matthew upstairs that she's coming, and hastily locks the door. We see that lock that Matthew installed is only partly engaged. The Desperate Housewives "danger is warming up on deck" music swells!

Upstairs, Matthew tears into Betty, yelling at her for writing such a terrible note. "What are you thinking?" he asks her once, he asks her twice. Betty insists that the police need to know the truth. Matthew: "The HELL they do! This is our chance!" Downstairs, Caleb shimmies and shakes the door open and then creeps up the stairs, so he's in prime eavesdropping position to hear Matthew say, "You want to do the right thing? Then call 911 and tell them you've got a killer locked up in the basement." Betty, sharply: "He is not a killer. He was confused. He didn't know what he was doing." Matthew tells her that Caleb knows a lot more than Betty gives him credit for. Betty says firmly that she's still going to mail the letter. Matthew: "If you do, you better hope to god they don't find us, 'cause they're not going to care how slow Caleb is; they'll just execute him." We see Caleb, on the darkened stairway, looking stricken. Slowly, he creeps back down to his dungeon and closes the door. Okaaaay, so Betty's been keeping a mentally damaged man -- her son I guess? -- drugged and (sometimes) manacled in her basement? That seems unusual, and cruel. Also, isn't whoever goes down to see Caleb next going to notice that his door wasn't locked?
