Here's the most inspired moment from last night's Chuck, in which Sarah thinks she's sending an S.O.S. to Chuck, and Morgan thinks she's making an erotic connection. Rrrrroww! We're glad Chuck is back, even though this wasn't the greatest episode.

NBC's Chuck will be following in the footsteps of Alias, swapping daddy issues for mom mysteries. The search for Chuck's mom will drive the fourth season, producers told Comic Con. Spoilers ahead...

Chuck started out as a show about a hapless nerd who gets the sum total of spy knowledge uploaded into his brain, but it's grown into a superspy action-drama-romance. We saw tomorrow's pivotal episode and talked to the creative team.

Fans who wondered where Chuck would be going after the end of the last season, the answer would seem to be the Fortress of Solitude. Well, metaphorically, at least, according to show producer Chris Fedak.
