I just started watching Chuck (the TV show with Zachary Levi) and am really enjoying it (yes, I am aware I am literally years behind the times). I was wondering if anyone knew of any stories where J2 (or Sam & Dean) are characters like Chuck and Sarah, one is smart (but maybe not achieving his full potential) and gets the intersect downloaded into his head and the other is the handler.

Or anything where one is a secret agent and the other is not but keeps getting dragged in some how.

Any suggestions welcome!
