though she makes more of an effort to give Chuck space with Jill. Sarah's feelings for Chuck and their ramifications for their mission are the focus of "Chuck Versus the Broken Heart", when Beckman decides Sarah and Chuck are too close emotionally, leading her to temporarily replace her with Agent Alexandra Forrest (the 49B). After the mission takes a turn for the worse, it becomes clear that the strong emotional bond between Chuck and Sarah is more of an asset than a liability, leading Beckman to reinstate Sarah's position.
