Chuck Versus the Sensei (S02E09)

Chuck, still stung from a personal betrayal, keeps busy with spy work as a coping mechanism. Casey's also reeling: He discovers his mentor (Carl Lumbly) has become a rogue agent. Meanwhile, Awesome's parents (Bruce Boxleitner, Morgan Fairchild) visit. And at Buy More, efficiency expert Emmett (Tony Hale) works to reestablish the "employee of the month" contest.
