Her father denies the appeal, but additional information emerges to postpone the execution . Sara's character plays a critical role in the episode "The Key", where Michael must take possession of a key to the infirmary door . He ultimately kisses her as a distraction to steal her keys, but is caught up in the moment and unable to go through with it . Instead, he has his wife meet Sara and steal the keys . His plan backfires when she discovers that Michael's wife has stolen the keys from her, and becomes very cold towards him . At the end of the episode, she has the locks to the infirmary door changed, thwarting his efforts . Michael is then forced to come clean in "Tonight" and reveals to her his intent to break Lincoln out of prison . Sara is confronted with the decision whether she should help Michael or not . Eventually, Sara returns to Fox River and unlocks the infirmary door . Horribly distressed at what she has done, Sara injects herself with morphine from the infirmary .

After her father alerts her of Kellerman's suspicious identity and her father's subsequent death in episode "Buried", Sara becomes part of the show's conspiracy plot as she holds the key (left by her father) to information that may exonerate Lincoln .
