<P> When her brother was expelled by Stanford University in 2003 he came back to Echo Park in Los Angeles to stay with her . For much of their lives growing up, Chuck and Ellie relied on each other, and after Chuck returned home, Ellie became one of his main sources of support as he recovered from Bryce Larkin's betrayal . At the beginning of the series, Ellie is throwing a birthday party for Chuck and has invited a number of her girlfriends for him to meet in hopes of helping him get past Jill . In "Chuck Versus the Subway", late in season 3, she learns that Chuck is a spy . In the season 4 opener "Chuck Versus the Anniversary" it is revealed Ellie and Devon are expecting a baby . Daughter Clara is born in the mid season episode "Chuck Versus the Push Mix". </P> <P> Ellie Bartowski - Woodcomb is portrayed by actress Sarah Lancaster . She first appears in the series at the beginning of "Chuck Versus the Intersect," when Chuck tries to escape his birthday party which she arranged to try introducing him to real women . She remains one of the most important anchors between Chuck and his real life throughout the series, and her safety is one of his foremost concerns . When Chuck discovered Casey had bugged the home he shared with Ellie, he was even prepared to threaten Casey if he found out he was spying on her as well . When Chuck's extraction by the government was imminent, he made a point of telling her goodbye, and later asked Sarah to tell her something to make his disappearance "okay ." </P> <P> Most of Ellie's appearances in the series have been as part of the side - plots involving Chuck's real life and coworkers at the Buy More, so she has rarely figured prominently into the main arc . Her most significant role in the main plot of an episode came in "Chuck Versus the Truth," in which Ellie attempted to treat nuclear expert Mason Whitney when he was poisoned by Reardon Payne . When Whitney later died, Payne, disguised as a police officer taking a statement, exposed Ellie to the same toxic truth serum he used on Whitney to find where he hid his nuclear codes . Ellie nearly died as a result of the poisoning until Chuck administered the antidote . Although she was in a coma during this time, Ellie became the first person Chuck told about his secret life . She was also among the hostages in the Buy More when Ned Rhyerson crashed his car into the store while evading the police . For her sake, Chuck convinced Devon not to go through with a plan to overwhelm Ned, and later identified himself as the Intersect to Mauser to prevent him from killing her . The bracelet Chuck gave to Sarah in the same episode was a charm bracelet Chuck and Ellie's father gave to their mother when Ellie was born . </P> <P> A major recurring thread in the series is the love / hate relationship she has with Chuck's best friend Morgan Grimes . Morgan has been in love with Ellie for a long time (or at the very least has a very strong crush on her), but Ellie is at first shown to barely tolerate him . However, as the series progresses, she and Morgan come to form something resembling a friendship, partly owing to them both missing Chuck as his spy life begins to interfere more frequently with his real life . Morgan also offers her support and comfort during a fight with Devon, where he admits he sees her as a sister (that he wants to have sex with so bad). Morgan's girlfriend Anna immediately takes a dislike to Ellie because of Morgan's long - standing crush . </P>
