This exclusive season finale photo certainly suggests a May 16 wedding for Chuck and Sarah, but don't start throwing rice just yet. "The wedding has been something we've been building up to, but this being Chuck, that doesn't mean everyone will survive until the 'I Do's,'" warns series co-creator Chris Fedak.

The episode, featuring the return of Timothy Dalton and titled "Chuck Versus The Cliffhanger," will indeed offer up a doozie — though Fedak's not saying any more about the ending. The biggest question mark remains if the ratings-starved series will make it to a fifth season honeymoon. Hoping for the best, Fedak says, "I would love to be able to tell the story of a Chuck baby."
