Chuck’s lies and secrets have been building for the last two and a half seasons, and they’ve finally come to a head. Chuck hasn’t flashed since assassin Rafe Gruber tried to kill Sarah, so Shaw tells Chuck he’s benched until he can figure it out. They’ll be going on their next mission—to track down a CIA agent the Ring has plans to turn—without him.
Chuck thinks he can’t flash because his feelings are all bottled up. He doesn’t have anyone to talk to. He tries giving Awesome a call, but Awesome shuts Chuck down. He is enjoying a weekend away with Ellie and he doesn’t want involved in Chuck’s spy life.
Morgan has noticed that Chuck is tense too. Morgan calls him into his office and asks Chuck to talk to him. But Chuck can’t open up to him without telling him his secret, so Morgan fires him as his best friend. With Team Shaw away on their mission, Chuck really is alone.
Chuck goes to his actual day job and spends some time with the Buy Morons. Big Mike tells them that someone is looking to buy the store. They want to interview the staff and take a look around. Their plan is to cut down to only essential staff; they have to stick together.
Before their interviews, Morgan is freaking out. This job is the only thing he has. So when Chuck gets called in for his talk with Del (Diedrich Bader) and Neil, he raves about Morgan the whole time. His best friend is the best thing about the store.
At a nearby hotel, Team Shaw is trying to track down the targeted CIA agent. Casey traces a Ring call and they get a description of the target. When Sarah looks outside, they find him: It’s Devon. Casey goes to search the room the call came from while Shaw and Sarah go down to warn Awesome. Devon is angry; Chuck told him he was out of all of this. But it turns out it was a false alarm. When Casey gets to the hotel room, it’s a setup. There’s no one there—just a remotely activated Ring phone. Shaw figures out that the Ring’s plan was to lure him away from Castle. Chuck is there, and he’s a sitting duck.
It turns out that Del and Neil aren’t potential buyers—they’re Ring operatives. They know Chuck is Agent Carmichael. They just have to find the entrance to Castle so they can uncover all of Shaw’s intel on them. They plan to keep Chuck and Morgan for leverage, and terminate the rest of the employees. But Lester overhears.
The Ring crew is still looking for the Castle entrance, so they head into the break room, where Morgan is getting rid of Jeff’s contraband. The Ring finds the tunnel behind the lockers while Morgan watches from the top of the vending machine. As soon as the coast is clear, Morgan follows and hears their whole plan.
When Morgan gets back to the Buy More, he tells Chuck all about the secret CIA base under the store and the Ring bad guys. He tells Chuck not to freak out; they have to play the heroes. Chuck suggests calling for help instead, but the Ring has shut down all communication in and out of the store. Chuck promises to help, but only if they evacuate the rest of the store. Unfortunately, that’s not going to work. Lester misunderstood Del’s death threats, and instead thinks the whole store is getting fired. They’ve barricaded themselves in until they get their jobs back.
Morgan is still determined to save the day and goes to charge in, but the Ring is waiting for them. Morgan and Chuck are tied up in Castle. Morgan is sure there’s been some kind of mistake, but Del can’t find Shaw’s files. Either Chuck tells him where they are, or Morgan gets tortured. Chuck has no other choice. He has to tell Morgan the truth—he’s a spy.
Team Shaw makes it back from the “mission,” but the Ring has locked them out of Castle. They can’t get in from any entrance to save Chuck, or their intel. Shaw wants to enact the self-destruct feature in the base, but Sarah begs him to give Chuck five more minutes to escape.
Down in Castle, Chuck apologizes to Morgan. He’s always wanted to tell Morgan the truth, but he had to protect him. Thankfully, Morgan isn’t angry. He’s thrilled. He wants to know everything, so Chuck tells him the whole story. Like everyone else, the part Morgan is most surprised about is the fact that Chuck and Sarah have never had sex. It must be hard for Chuck to work with someone he so obviously loves.
After talking it out with his best friend, Chuck finally admits to himself that he still loves Sarah. And with all of his feelings off his chest, Chuck can finally flash again. He takes out Del’s whole team (with a minor assist from Morgan), and they exit Castle right before Shaw calls it in.
Now that Morgan knows everything, Shaw wants to put him in Witness Protection, but Chuck says hell no. They’ve been best friends for 22 years; Morgan will never betray him, and Chuck needs him. He’s staying put.
And so are the rest of the Buy Morons. After their barricades, Nerf guns, and a riveting performance by Jeffster, Shaw calls, pretending to be from corporate. They showed incredible store loyalty. The Buy More is no longer for sale.
Awesome is still really rattled by the spy stuff. He has to look out for himself and for Ellie, so he tells her they should join Doctors Without Borders and go to Africa.
