Chuck Versus the Cubic Z (S04E03)

Villainous nemeses Hugo Panzer ("Stone Cold" Steve Austin) and Heather Chandler (Nicole Richie) return to haunt (and hunt) Chuck and Sarah. The conniving Chandler, however, stirs up Chuck's curiosity when she claims she has information about his mother. Meanwhile, Morgan preps the store for an all-important video-game release.
