Love, and a faulty Intersect, might be driving Chuck crazy — crazy enough to get him locked up in the psych ward. Meanwhile, Ellie's getting wooed by the Ring and Morgan's getting his groove back.
Chuck has been trying, very hard, these past two weeks to find a way to integrate the relationship evolution with the espionage progression. I'm sure the producers realize that a happy Chuck makes for a boring series. (We've talked about that, haven't we? Okay, just making sure we're together on this.) And so this week's episode, "Chuck Versus the Tooth," looked like it was going to add something new and interesting into the mix: insanity.
