General Beckman promotes Casey to Colonel and orders him to bring back Chuck and Sarah. Casey tracks Chuck and Sarah to a motel in Barstow, CA near the Fulcrum facility code-named Black Rock, where he arrests them, despite some interference by Fulcrum. Suspicious of Casey's involvement in Chuck's disappearance, Devon breaks into his home. Casey confronts Devon but is prevented from killing him by Chuck and Sarah, who escaped their holding cell during a blackout. Chuck reveals the truth of his spy life to Devon. Sarah and Chuck return to Black Rock, followed by Casey who offers his help. The team retrieves Steve and the new Intersect before the Fulcrum base is demolished by an airstrike. Steve reveals to Chuck that the Intersect has been erased from his mind after he viewed the new Intersect's images. Beckman declares their operation to be over and Morgan quits the Buy More to regain his honor.

Chuck vs. the Ring

Air date: 4/29/09

Chuck declines General Beckman's offer to join the new Intersect team and quits the Buy More with Casey. Ted Roark's appearance at Ellie and Devon's wedding leads to a gunfight and ultimately his arrest. Meanwhile, the church wedding ceremony is accidentally ruined by a performance by Jeffster!. Chuck uses his government pay to give Ellie the beach-side wedding she has always wanted, allowing her and Devon to finally wed. A member of Casey's special forces team is revealed to be a traitor (and later a member of an organization called "The Ring") when he kills Roark and three other US Marines. When Bryce is ambushed by operatives of "The Ring," Chuck, Sarah, and Casey rush to rescue him. While Sarah and Casey are engaged in a gunfight, Chuck goes into the Intersect room, where he finds Bryce with a fatal gunshot wound. Heeding Bryce's warning, Chuck destroys the Intersec, but not before downloading it into his head. Using his newly implanted knowledge of martial arts, Chuck effortlessly defeats the agents holding Sarah and Casey captive.
