'I'm doing something weapons-related,' an agent of The Ring revealed to Chuck who goes undercover to find out what he's up to.
Someone has built a new intersect and makes use of the skill to combat for The Ring. In "Chuck" February 1 episode, Chuck gets his very own asset who is caught up with The Ring. He thinks he can handle his asset all on his own but Sarah and Casey feel the need to intercede.
Back at Buy More, Chuck juggles his two lives as he trains new Nerd Herder Hannah (guest star Kristin Kreuk) and continues life as a spy. Morgan, Jeff and Lester do some recon work to learn more about Hannah. Creators Josh Schwartz said in a press conference that Hannah's arrival at the store will set a few hearts aflutter, not just Chuck's.
Also in the episode called "Chuck Versus Nacho Sampler", Awesome must lie to Ellie when she starts to ask questions about Chuck.
