13. Chuck Versus the Goodbye

Complete story — includes the ending

Chuck's friends and family band together to take down Quinn. Sarah realizes that Chuck was telling the truth about their relationship, but leaves to find Quinn and take revenge from him, as she can't remember any of her feelings for Chuck. Two weeks later when Sarah returns to ask Chuck's help in tracking down Quinn, Chuck offers his services for a final mission to take down Quinn and recover the final pieces of the remaining Intersect. Ellie informs Chuck that the Intersect can be used to reprogram Sarah's memories. Sarah and Chuck soon discover that General Beckman has the final key for the Intersect, but Quinn beats them there and plants a bomb under General Beckman's chair that will detonate if Beckman leaves her chair or the music ends. As soon as the last note of Antonín Dvořák 's Symphony No. 9 fades away, Jeffster! plays A-ha 's " Take On Me ", while Morgan conducts the orchestra to play along. Sarah apprehends Quinn and kills him, recovering the Intersect. However, Chuck has no choice but to upload the Intersect to open a case which contains the bomb. In the process, Sarah remembers that a pornographic computer virus can be used to destroy the computer and stop the bomb, as it did in the pilot episode. After the final mission, the gang says its goodbyes. Beckman says her offer to them about rejoining the agency is open if they ever want to save the world again. Casey hugs Chuck goodbye and leaves. Sarah also tells Chuck that she is leaving to find herself and needs time to think and be alone to decide about starting over. At the Buy More, Jeff and Lester describe the previous night's events to Big Mike, who is skeptical until a German record producer arrives to offer a recording deal with Jeffster!, which they accept. Casey tells Alex and Morgan that he is leaving to be with Verbanski. Alex and Morgan tell Casey that they are moving in together, which he approves of by giving them the keys to his apartment. Ellie and Awesome pack up their belongings for their move to Chicago, as Chuck reassures them. He leaves dejectedly, before Morgan gives him a pep talk to pursue the girl of his dreams and follow his heart. His instincts take him to the beach where he met Sarah at the end of his first mission. Sarah recognizes the place is important but is unable to remember the details to which Chuck tells her that this is the place where she asked him to trust her after their first mission and asks Sarah to do the same. He urges Sarah to trust him and no matter what she decides he would always be there for her. Sarah finally opens up to Chuck and asks him to tell their story, and he does in flashbacks. Finally, Chuck mentions Morgan's theory that a kiss will bring back Sarah's memories. Sarah looks back at him and even though Chuck isn't sure about Morgan's theory she interrupts him from saying anything else and asks Chuck to kiss her which he does. As they continue kissing, the scene fades back into black, which marks the end of the series.
