GREEN EYED MONSTER—JORDANA BREWSTER AND TONY HALE GUEST STAR—Chuck (Zachary Levi) and Jill (guest star Jordana Brewster) are enjoying the honeymoon stage of their rekindled relationship. The two lovebirds plan a weekend getaway but have to cancel at the last minute when Casey (Adam Baldwin) and Sarah (Yvonne Strahovski) inform Chuck that he is needed for an immediate mission to find corrupt agents in the CIA. Jealousy erupts when Jill finally meets Sarah and learns that Chuck and his handler must pose as a couple. Chuck does his best to reassure Jill that his relationship with Sarah is purely business but only finds himself in more trouble when his mission does not go as planned. Meanwhile, corporate efficiency expert Emmett (guest star Tony Hale) is out to get Chuck and interrogates Morgan (Joshua Gomez) to get some dirt on his best friend. Scott Krinsky, Vik Sahay and Julia Ling also star.
Emmett busts Morgan for using the Buy More’s home theater room after hours to “fraternize” with fellow employees.
Team Bartowski successfully completes a mission to steal a list of Fulcrum’s double agents within the NSA, but Fulcrum wants it destroyed before Casey or anyone else at the agency get their hands on it. A Fulcrum agent, Winterbourne, takes Jill hostage at the Museum of Natural History to get the list back from Chuck, resulting in some prehistoric damage.
