<P> Sara is shown in the series as a compassionate yet introverted doctor who treated each one of them with the same cordiality and respect . Given this fact, she has little sense of humour and is incorruptible . In the episode "The Rat", Sara's father questions her motive for helping Lincoln Burrows, to which she replies, "It's my job to advocate for (my patients)." Sarah Wayne Callies, who portrays Sara Tancredi, remarks that the character "feels a certain level of responsibility to these guys . Partly because who her father is...she's the kind of person who would rather take a stand and sleep well at night than have a peaceful family ." </P> <P> In the second season, Sara becomes part of the conspiracy plot of the show after her involvement in Michael and Lincoln's escape, and her father's later pursuit of information concerning Lincoln's case . She is continuously chased by covert agents after the death of her father in "Buried". Sara later confides in Michael in episode "Chicago" that the two things keeping her going are her feelings for him and that she wants to seek justice for her father's death . The character is described by Jay Bobbin from Zap2it.com as "gutsy", while TV Guide's Maya Schechter remarks that Sara is "one tough cookie". Regarding her character's change in the second season, Callies says, "She's just someone who has really rushed at life and absorbed experience with real enthusiasm . She's getting a lot more than she bargained for right now, and I certainly don't think she'll be the same person after this ." </P> <P> Sara Tancredi was introduced to the series as the daughter of the Illinois governor and the prison doctor who the protagonist frequently visits to obtain his insulin shot . The background story of the character, revealed in the sixteenth episode of the first season, was not actually conceived along with the original conception of the series . Callies commented in an interview that it was the "very first inkling" that she had about the character's past . Also in the same interview, the actress mentioned that during the production of the series pilot, she had suggested to Prison Break creator Paul Scheuring that "it would be interesting to play her as a recovering alcoholic". </P> <P> The character's continuation as a major role in the second season was a "surprise" to Callies since the second season revolves around the lives of the eight fugitives outside the prison . The actress states that it is "some of the most creative storytelling for women on TV right now" and that she was given "lot of latitude in establishing a sense of who (the character) is". As the characterization of Sara continues to develop, Scheuring describes the character as "one of (the series') strongest components". </P>
