Scott Krinsky shared a minor spoiler with the TV Guide Magazine on Chuck and Sarah:
"I could imagine that if Chuck and Sarah were to get married, how could you not find a way to include Jeffster in that, right? If the wedding happens, there's probably a good possibility that [he'll be booked as the wedding band]."
And after four seasons, Krinsky says he's used to the speculations about whether or not the show that's perpetually on the bubble will get picked up for another year.
"It's Chuck — it's part of the excitement! It feels gratifying to say that we've been around for four seasons, and the fans are already starting their campaigns. We have them to thank."
