Chuck asked, "Our thing under the undercover thing. Is this ever going anywhere?" He got the answer he didn't want, but in this AU, Sarah made sure Chuck had a reason to choose Hot Dogs over sandwiches. The parallel AU is 1x08-2x04, with a lot about their relationship under the cover.

What happened "in between" the episodes we saw over five seasons of Romance, Adventure, Humor, Friendship, Family, Friends, and Drama in Chuck? Chapters are tags/post-eps/epilogues, setups/prologues, or simply "in between." The genres and characters match what happened in the show. Enjoy this long trip down memory lane.

Chuck and Sarah's first and second first dates were stopped by flashes and people almost killing Chuck. What if Sarah couldn't wait so she was a couple minutes early for the third first date? This two-shot AU is from Sarah's POV.

Casey's grunts practically formed their own language. Early in "Chuck vs the Crown Vic," Chuck started identifying them. It's great that he understood his spy protector, but what about the rest of us? Hopefully, this Grunt translation dictionary will help.

What if your daydreams came true. This is the early part of "Chuck vs the Seduction," but with a twist.
