Jeff and Lester blew up the Buy More. In the final moments, Chuck goes to his father's house and discovers a basement loaded with spy records -- including one about his mother!

What's Ahead: Chuck and Sarah's relationship will remain strong, but he's going to have make a big adjustment when Sarah continues working as a spy while he is unemployed. Chuck and Morgan will scour the globe looking for his long-lost mother.
