Full Story[]

A flashback to 2002 shows Chuck taking Jill to a carnival, where he bribes a carny to stop the Ferris wheel at the top, even though he is afraid of heights. Awkwardly, he expresses his feeling for her.

In the present, in Castle, Beckman is horrified that Jill is Fulcrum and that Chuck is with her. Sarah says that Chuck left his watch behind and turned off his cell phone; Beckman orders them to find Chuck by any means necessary. As she signs off, Casey voices the thought of Chuck being tortured, though Sarah promises that Fulcrum doesn't know Chuck is the Intersect or that Jill has been burned.

Chuck and Jill meanwhile, had stopped over in a nice hotel and spent the night together, and when Jill goes for a shower the next morning, Chuck checks his phone and finds 14 messages from Casey on it. He then notes Jill's phone buzzing, and flashes on her text, it is actually a coded message for "Meet Leader, Urgent." Shocked at the implication, he tells Jill that he's going out for coffee. As he tries to run, he is pulled aside by Casey and Sarah, who berate him for sneaking off. He then tries explaining that Jill may be Fulcrum but they already know.

Chuck tries denying it, pointing out that Jill has no Fulcrum code name, but Casey tells him her code name is "Sandstorm" and the Intersect confirms it. Chuck reels from the revelation that Jill is a bad guy. Chuck is told to return to her, if they are to keep her unaware of what he knows. He points out that Fulcrum is looking for the Intersect, which just so happens to be him. Sarah assures him that Fulcrum don't know that, and promises that she and Casey will protect him.

When they return to Chuck's apartment, Jill asks if they can go on another date. After a good-bye kiss, Casey, who was spying from his window, taps the glass to signal Chuck. When joins them, Sarah asks if he's all right. Still reeling, he asked how Jill become Fulcrum, Beckman, appearing on the computer screen, theorizes that she must have been recruited at Stanford. Chuck then asks if anyone in his life isn't a member of a covert espionage faction. Beckman says his flash mentioned an agent called Leader, she wants hims to use his relationship with Jill to see if she makes contact with Leader. Sarah objects, seeing Chuck could barely handle a goodbye with Jill, and could blow his cover. Beckman asserts that it is the best opportunity to infiltrate Fulcrum but is willing to let Chuck recuse himself. Suddenly firm, Chuck agrees to the plan, deciding that it's payback for the girl who betrayed him twice.

Chuck returns home to find Ellie obsessively cleaning for the arrival of Devon's parents for Thanksgiving. Though he assures her that everything will be fine, Ellie says that Devon's mother is very judging. Chuck finds Morgan coming in through his window to ask about Jill. Morgan then smells turkey and goes to find it, Ellie asks him to taste. Though he finds it good, she finds too dry and throws it in the garbage, freaking out Morgan. She then tells Morgan he's not invited to Thanksgiving dinner since he is far from perfect.

At the Buy More, Morgan is in shock, though Chuck promises to smooth things over with Ellie. Big Mike then pulls Morgan aside, stating that because he, Jeff, and Lester don't have any plans, they need to stay in the Buy More to guard the stock for Black Friday, as they have a great deal of inventory.

Chuck receives a call from Jill, who is taking him on a surprise date that night, and asks that he leave his handlers for the night. Chuck then goes to Castle to consult Sarah on how to survive the night with Jill. She explains that Jill will test him and catch him off guard when he's most vulnerable, like after a kiss. She coaches him through a kissing scenario, which Casey interrupts to inform them that Jill is apparently taking Chuck to a concert.


Later that night, Jill takes Chuck to a carnival, not a concert, where she reenacts the moment on the Ferris wheel. Jill says, "I'm sorry, Chuck," before pulling a gun on him. She then explains that she works for Fulcrum. Chuck tries pleading her not to do this, and points out that if she pulls that trigger, it will be who she is. Jill relents, but informs him that Leader is waiting. Her job is to take him out of here and if she doesn't, Fulcrum will eliminate both of them.

Casey and Sarah race to find Chuck, but learn that he's not at the concert but at the carnival. Jill tries leading Chuck through the carnival but then spots Leader, who tells Jill that Chuck's handlers are closing in, therefore, she has to shoot him. Jill turns on Leader, giving Chuck the opening to run away. Leader, knocking out Jill, chases after him and corners him in a closed Gravitron ride. Chuck pushes the button to activate the ride, sending them on a spinning centrifuge. While the Gravitron is still spinning, Leader tries to reach Chuck, but Chuck instead flies into him as the ride stops. He then flees into the fun house, and the hall of mirrors. Jill enters, asking Chuck to trust her. He tries asking when she joined Fulcrum. She explains that Fulcrum gave her everything she ever wanted, though she regretted some of the things she had done. As Chuck tries searching for her, Leader appears. But before he could shoot Chuck, Jill shoots him. As she leads him out, she is arrested by Casey and Sarah, despite Chuck's protests that she saved him.

Next day, at the Buy More, Big Mike lays out the plan to Morgan, Jeff, and Lester: they stay locked in the store, and if anything happens, they call him. Morgan asks if this is overkill. Big Mike tells him of the first store he worked in 1988, which was robbed on Christmas, closing it down before New Year. He then leaves and locks up the store.

Down in Castle, Casey and Sarah hook Jill up to a lie detector to interrogate her. She confesses to knowing of a Fulcrum medical facility, an office in Los Angeles where he could be. Sarah warns Chuck that Jill can't be trusted.

Back at the Buy More, Jeff is running a trip wire. Morgan is unsatisfied with the mediocre dinner they are having, and he convinces them that he could bring back real food. They are able to hot wire the doors to enable Morgan to get out. Unfortunately, they tripped all the silent alarms, alerting Big Mike on his fishing trip, who receives the alert and races back to Burbank.

Ellie's efforts for dinner are wasted when she learns that Devon's parents aren't coming, and she lets out a sigh of relief. She and Devon then find Morgan pulling her discarded turkey out of their garbage. Ellie hugs him, apologizes, and re-invites him to dinner. He then lets slip that Chuck had been seeing Jill, Ellie goes mama bear, and insists he spill everything, he agrees to if he can invite two more people to dinner.

Down in Castle, Chuck enters the interrogation room, where he asks if Jill slept with Bryce Larkin, she answers no; the lie detector confirms it. She apologizes for dumping him in the first place, which was on orders from Fulcrum when he was expelled from Stanford. He asks if they could ever start again, and when he releases her cuffs so that he could kiss her, he is unaware that the lie detectors reads negative. When Sarah and Casey return with Leader, Jill has broken free and holds Chuck at gun point, forcing them to release Leader. As Chuck's handlers are led into a holding cell, he is forced to access Castle's computers under threat of his friend's deaths; he realizes this reconnect was all an elaborate attempt to get into Castle. As Jill forces Chuck into a holding area, he tries asking what are they looking for. Jill answers that they are looking for Bryce, stating that he "stole" something from Fulcrum. As she locks Chuck up and leaves, Casey guesses that they are searching for the Intersect.

Chuck has something to even the odds -- the Castle manual. Using it, he locks Leader and Jill out of the base's computers, activates the communications jammer to prevent them from revealing Castle's location to Fulcrum, and triggers the trouble alarm to alert the CIA, who are sending a squad. Walking up to the bulletproof glass, he states that the nerd in him wants to say checkmate. Leader has one last move: planting a bomb on Sarah and Casey's cell, which would kill them, unless Chuck shows the way out. Chuck reluctantly complies, but as soon and he and the Fulcrum agents leave, a message appears on Casey and Sarah's keypad, saying that Chuck had unlocked their door, and he's leading them to the Buy More.

They emerge from the secret door in the Home Theater Room. Chuck then springs the trap, when Leader falls over Jeff's trip wire, before his handlers ambush the Fulcrum agents. While Casey goes hand-to-hand with Leader, Sarah goes looking for Jill, as she searches the employee lunchroom, Jill comes up behind her and is ready to shoot, but Chuck finds her and coaxes her to go with him.

Meanwhile, Casey's fight with Leader doesn't go as well, and he is knocked to the ground. But before Leader could shoot him, Big Mike returns. Thinking Leader a thief, he tackles him, knocking him out. He asks Casey if Morgan put him in charge, and Casey answers yes.

Chuck takes Jill outside to the the Herders, "'re taking the Matrix, okay? All-wheel drive, touch screen navi, iPod capability, and a full tank of gas. It's the perfect getaway car." As she gets in, she asks Chuck to run way with her. Chuck then uses the Herder's in-built detention mode to detain her. He explains that he was going to let her go, but when he saw she was going to kill Sarah, that made the decision for him. He declares that she is under arrest, and he is breaking up with her, then walks away.

Later, Chuck apologizes to Sarah for letting his trusting nature get the better of him. She assures him that he's not like any other spy and that's good. They then walk into his apartment, seeing Jeff and Lester sitting at the table. Ellie asks Chuck about him being with Jill, having been told by Morgan. He assures her that his past is behind him. They all then sit down for Thanksgiving dinner.
