Iran bunker. Chuck says that, since they're going to kill them anyway, can they tell him about one of Volkoff's prisoners named Frost. Mack says she's no prisoner; she's their boss. Casey and Morgan arrive and start messing with the computer compartment outside the cave. Important: Casey's wearing rubber gloves while he messes with it and taps in the computer, which gives them control of the bunker: cameras, sewer, lights, etc. They get the camera on, and see Chuck and Sarah chained up. Mack continues to Chuck that Frost is Volkoff's right hand, and he sends her in when there's a problem, which then disappears. Back outside, Casey makes Morgan put on the rubber gloves and tells him how to turn off the lights when he hears Casey says the word "security." Morgan points out it's three to one, but that's how Casey likes it. He heads in.
In the bunker, Packer and the gang pull their guns on Casey and force him to drop all his weapons (they know the guy, so they know there are a lot). Casey says he would have come unarmed but wasn't sure what kind of security he'd run into. Morgan tries to kill the lights, but fails, so Casey repeats himself. Morgan tries again and releases water all over the floors. He tries again and cables start flickering. Packer sends his other guys to get the gold and asks Casey if there are any more surprises. They use Casey's hand to open the door and then chain him up as he tells them there are special forces outside. Mack says he might get lucky and shoots outside the bunker. Morgan: "Ow!" T.I.: "Was that a little girl?" Morgan was skimmed on the arm, then surrenders easily and comes inside. They realize he's not a threat, so they don't even chain him up. They tell him not to move, then start emptying the vault. Morgan has some sort of "Couch Lock" revelation seeing a hanging electric cable and the water everywhere. Casey tells Chuck and Sarah to lift their feet up and Morgan grabs the cable and jumps into the water with it. It shocks the other guys, and Morgan, too.
Cut to Sarah's, then Casey's, then Chuck's faces over Morgan as he comes to and asks what happened. Chuck says he took 10,000 volts, and Sarah adds that he went into cardiac arrest and they lost him for a minute. Morgan: "I died?" Casey: "For like three seconds." Chuck tells Morgan that's the bravest thing he's seen anyone do, and to never do it again. Morgan would like to go home now, please.
Buy More. Jeffster! approach Casey to tell him that they do "installs" like the one he did twice a week, so he can count himself in. Jeff tells him they wake up in some of the best Dumpsters in the city. They leave him, and Morgan finds him to ask if they're good. Casey grunts, and Morgan takes that as a yes. Morgan tells him that he and Alex are pretty much over anyway, then invites Casey to a party. He tells him to think of it as the people who'd really be there if there were an actual funeral. Cut to the party. It's Ellie and Awesome, Sarah and Chuck, and Morgan. Casey shows up and everyone's super-nice to him. Then there's another knock. Morgan answers it, and it's Alex. She looks a little upset, but as he tries to apologizes for everything, she cuts him off and says her dad told her what happened: Morgan dumped her because Casey said he had to, but that Morgan stood up to him and changed his mind. She says that couldn't have been easy, and it was brave. Morgan goes along with Casey's lie and says he wants to be with her if she wants to be with him. She does. Morgan goes into the kitchen and thanks Casey. But, lest we think Casey's gone totally soft, he grunts and then tells Morgan if he breaks her heart, Casey breaks his everything.
