Sarah Lisa Bartowski (née Walker)[6] is the alias[2] of one of the main characters of the television show Chuck on NBC.

She is portrayed by Yvonne Strahovski and is one of two agents assigned by the NSA and CIA to protect Chuck Bartowski after he unwittingly downloads the secret government computer known as the Intersect into his brain.

Although apparently "recruited" at this point, flashbacks make it clear that she continued in high school; several of the popular children cruelly mocked her as the "jailbird's daughter" because of her father's imprisonment.

One of the complications and the main focus on the development of her character throughout the series is that although initially she insists this is only part of her cover, a genuine romantic interest grows between them.

By the end of the season, Sarah displays a willingness to go to great lengths for Chuck, and is even prepared to go rogue and draw her gun on another CIA agent attempting to take him into government custody.

[22] However, the rebuilt Intersect is sabotaged, pulling Chuck back into his spy life and re-establishing Sarah's professional barrier.

[24] Yet another love triangle arises later in the season with the arrival of Cole Barker, who (like Bryce) is a suave and formidable spy, but that only goes as far as a kiss.

However, the replacement agent, Forrest (Tricia Helfer), failed to effectively protect Chuck and he refused to work with her because of her methods.

Team Bartowski's new leader, Daniel Shaw, began romantically approaching Sarah in "Chuck Versus the Mask."

Chuck also finds out her real name after he overhears this conversation while posing as an assassin the Ring hired to kill Shaw.

Although pleased with Chuck's successful handling of the assignment, Sarah was greatly disturbed when Shaw instructed her to order him to kill a rogue CIA agent.

After she obtains the truth from Morgan, she confronts Chuck and along with Casey, goes through her relationship with Shaw to find any clues as to his whereabouts or plans.

In "Chuck Versus the Ring: Part II", Sarah and Team Bartowski carry out a plan to expose Shaw at a security convention.

The plan succeeds and they're able to identify and detain the Ring Elders, but Shaw manages to escape just as Sarah walks into his office to find Chuck heavily debilitated by his latest attempt at flashing without the Governor.

"Chuck Versus the Anniversary" reveals that the two have been assigned to investigate Volkoff Industries, run by a notorious black-market arms dealer.

Most of Sarah's actions for the remainder of the season revolve around this combined mission and around the personal challenges from her past that she confronts as she and Chuck decide to commit to marriage.

When she finally finds him, Sarah resolves her expressed fear of marriage in multiple previous episodes by telling an unconscious Chuck that she loves him and wants to spend the rest of her life with him, with or without the Intersect.

Just as Chuck is about to propose to her, she is pulled away to establish her cover as a rogue CIA agent and goes undercover in Volkoff Industries to help Mary bring it down.

After Alexei Volkoff is defeated, Chuck finally proposes to Sarah while waiting for the arrival of Clara Woodcomb.

Sarah had long suspected her teammate Zondra of being a traitor working with Gaez, having found a transmitter in her boot.

When they return from their honeymoon two weeks later she and Chuck reveal to Casey and Morgan that Hartley turned over all the wealth of Volkoff Industries to them.

Sarah asks if they didn't along, why he was here now and Casey pulls out an envelope out of his jacket and sets it down for her, saying that Chuck ended up making them both soft.

Sarah then started pursuing Quinn, learning that he's trying to reassemble The Key, a device that can modify the Intersect's original function.

Sarah is forced to shoot Quinn when he reaches for his gun, ruining their chances of deactivating the bomb Beckman is sitting on.

Sarah suggests searching for "Irene Demova" (a porn virus) on the Internet which Chuck does and is surprised that she knows about, pointing out it was from five years ago and the bomb is disarmed after the virus crashes it Afterward, Sarah felt unsure of herself because her memories have still not fully returned and tells Chuck that she needs time alone to figure out who she is.

On February 12, 2007, Australian actress Yvonne Strahovski was announced[26] for what was then the role of "Sarah Kent," joining Zachary Levi (Chuck) and Adam Baldwin (Maj. John Casey).

[27] The character is a reversal of typical action film gender roles, with Sarah Walker portraying the protector and fighter while Chuck is the more emotional "brain."

She considers this one of her favorite parts of the role, especially the fight scene in "Chuck Versus the First Date" against Michael Clarke Duncan's towering Mr.

At the 2009 San Diego Comic-Con, Josh Schwartz and Chris Fedak revealed that Sarah's mission would shift somewhat in Season 3.

Season 5 has Sarah become more interested in having a normal life, to the point of admitting she was excited about the possibility of having a baby, which prompts her to start questioning the constant risks she and Chuck put themselves through in their line of work.
