Chuck

We've already heard from Chuck's creator, Josh Schwartz, that the last half of this season is going to have some game changing episodes.  Now, Schwartz has hinted to Kristin Dos Santos a little more about what that means.

According to Schwartz, Chuck still doesn't know that Sarah was trying to save Chuck's life when she killed a man in front of him.  Hey says "that's a dynamic that obviously is going to be complicated."

He then adds that "there's a very sexy MI6 agent who comes in to help on a mission for a couple of episodes, played by Jonathan Cake. He's a real sort of badass Gerard Butler - type who definitely catches Sarah's eye. There are a couple things that are going to happen towards the end of this season that are sort of a point of no return for Sarah and Chuck."
