Buy More. Morgan gets a text from Alex that says, "Great seeing you. Movie marathon soon? Xo." He calls it a disaster, then asks Big Mike for advice. He explains he met this girl who might be "it," but there's this little detail of her being Casey's daughter. Big Mike agrees Casey's not the dad you want hating you, but there is no bodily limb worth the love of a good one. So Morgan needs to determine if she's worth it. In Castle, Sarah has the computer analyzing the photos of the weapons room while Chuck tries to move on to more questions from the book: The next ones are about sex. Sarah protests they have a mission, but Chuck think it's important to talk about the difficult stuff to your partner while they sleep. Sarah says she's not going to do that, and this book sounds ridiculous. Chuck says Dr. Fred is world-renowned and then accidentally beckons toward the monitor at the Buy More, where Dr. Fred's table is set up for signing autographs. Sarah zooms in and sees the title of the book. She thought they were going to take it slow, and Chuck says they are, but someday he'd like to talk about marriage. She wonders why they always have to talk and push and change things? Why can't they just be? Chuck flashes on one of the pictures from the Costa Gravan weapon as Sarah tries to keep talking. There's some minor confusion when he tells her it's nuclear.

General Redhead yells from her screen into Casey's apartment, "Costa Gravas is nuclear?!" Generalissimo admits it's true that he has a control panel in his basement. There are nuclear sites in the jungle, aimed at different cities, and it takes two keys to run it. He has one key around his neck. Turrini seems to take note of this, and Casey notes that. General Redhead asks where the other key is, and he mumbles that he gave it to his wife. Turrini asks if Generalissimo can please rest. General Redhead asks Chuck and Sarah, who've been on their own video feed from Castle, to go to a private line. She's sending them back to Costa Gravas after they check in with Casey. Speaking of Casey, he, the Generalissimo, and his henchmen are outside so the Generalissimo can smoke. Casey tells the Generalissimo he never imagined he'd be taken down like this. In fact, Casey wrote a paper theorizing on who would take him down: someone whose politics would never move to the center, as the Generalissimo's have; and someone who couldn't take his eyes off Amor. Casey and Turrini draw guns on each other at the same moment. Casey calls Generalissimo around behind him. Turrini tells Casey not to make him shoot a man in a wheelchair, so Casey stands up: "Better?" Turrini says Generalissimo is coming with him, since they need his key. Casey disagrees, but all the guards are apparently with Turrini. Generalissimo sees Casey's not going to back down, so he bashes him over the head with a planter. He apologizes to his Angel of Life, then leaves with the bad guys under the condition that they don't kill Casey.
