Chuck Versus the Ex
Meanwhile, at the Buy More, Big Mike nearly chokes to death, which leads company efficiency expert Emmett Milbarge (Tony Hale) to implement a mandatory CPR course taught by Devon Woodcomb.
In 2003, having been expelled from Stanford University and hired at the Buy More, Chuck Bartowski walks along a row of sorority houses wearing a green shirt.
He stops at the house where his girlfriend Jill Roberts (Jordana Brewster) lives to explain that he was expelled under false accusation of stealing tests.
At the present-day Buy More, Chuck listens to a playlist before being sent by Emmett Milbarge (Tony Hale) to respond to a technical support call for a biotechnology conference at a nearby hotel.
As Jill reminisces about how she would change things about their past, her boss Guy Lafleur (William Abadie) arrives, and Chuck flashes on him.
Chuck protests, as Jill was the one who broke his heart and destroyed his confidence, but Sarah Walker persuades him to take on the assignment to gain closure, and John Casey remarks that he can get his "mojo" back.
During a conversation about their past, however, Chuck turns off the bug, but Casey gains access to it through an override from the team's van and switches it back on.
Later, Casey and Sarah visit Lafleur's apartment, where he is attacked and thrown off a balcony to his death by an assassin who escapes them.
Chuck receives an urgent message from Casey, who is in the conference room as Sarah prepares to give her speech.
Chuck recruits Jill, being forced to reveal his involvement with the CIA and NSA and surprises her by bringing an entire squad with him.
While waiting for Jill to arrive in the conference room, Chuck considers whether passing the cure on through saliva would work.
After all the people are cured with the antigen, they are allowed to exit the building, and Chuck and Jill share a long kiss, as Sarah watches in frustration.
At Castle, Beckman informs the team that the assassin Sarah killed was a Fulcrum agent, as the organization mainly consists of rogue CIA elements.
Big Mike assigns Emmett to teach the entire Buy More staff CPR, and Devon Woodcomb agrees to be their instructor, preparing them for a test.
Lester conjures a brilliant plan to quickly get the answers: Jeff is to choke on a pen cap as Devon performs the Heimlich Maneuver.
Of the episode's conclusion, Goldman wrote, "Chuck's attempts to save the day led to some very funny situations, culminating when he had a would-be ingenious plan to use saliva to process the cure Jill had put within him, and kissed Casey.
