Operation Wedded Bliss: will Chuck and Sarah finally become Mr. and Mrs. Superspy? Season Four's 24 laugh- and action-filled episodes include the duo's romance from proposal to planning to the big day. Yes, Chuck's in love, but he has more than romance (and the Intersect) on his mind. His mom comes in from the cold, escaping the evil control of an international arms dealer to become part of the Nerd Herder-turned-spy's life - and making it even tougher for Chuck to keep his professional and personal worlds separate. On some days, Chuck outwits assassins and out-martial-arts hordes of black-clad bad guys. On others, he pursues Sarah and prepares to become a doting uncle. On most days, he does it all!
