The beauty of tonight’s two hours lay in the way Zachary Levi wore Chuck’s emotions so nakedly, and in the way Yvonne Strahovski conveyed just how badly Sarah wanted to believe in the life he described. I bitched last week in this space about how the show sometimes treats Sarah as an unequal partner in their relationship. But the symmetry of events that echoed those in the pilot restored that balance nicely in its final hours. Whereas she was his initial shoulder to cry on in a new world order he didn’t understand, so now will he be hers.
