Team Bartowski's made their way back, but Sarah and Agent Superman are locked out at the Orange Orange. Casey's at the Buy More, where the gang greets him by shooting him with toy guns until Big Mike tells them to cease fire. They tell Casey what's up with their revolution to take down the man, and he wants in. Lester asks how they know they can trust him, that he's not some sort of spy for the man, and Casey responds with the best line of the episode: "Because the only thing I hate more than hippie neo-liberal fascists and anarchists? Are the hypocrite fat-cat suits they eventually grow up to become." That works for Lester, so they let him in.
In Castle, Morgan's like, "You're a spy," and Chuck reminds him not to freak out. But Morgan just keeps repeating it. Diedrich asks for the files, but one of his cohorts comes in and tells him that "Colonel Casey and Agent Walker" have decided to join the party. Morgan: "Casey and Sarah are spies too?" Diedrich tells him he has a lot of catching up to do, and the Ring operatives leave to deal with the rest of Team Bartowski. Once they're alone, Morgan's like, "No, no, no, no, no. I can't believe it. All this time? You kept this a secret? From me?" Chuck apologizes and tells him how badly he wanted to tell him, because he hated making the plans and breaking them, but he had to protect him. Morgan says wow, and then, excited, "Wow! I don't. My best friend is a spy?!" He says it's the best news he's ever heard. He thought he'd lost him, but he was out saving the world. He says he's officially re-hired as his best friend. Chuck sheepishly says that's great and thanks him. But now Morgan wants to know everything, and since they both think they'll die here, Chuck goes ahead and starts at the beginning: "This all started about two and a half years ago, when I got an email from Bryce Larkin."
