It felt like she could be Meredith's sister, but she had a depth that was very interesting."[8]

Invasion (Grey's Anatomy) Under the supervision of Dr. Derek Shepherd (Patrick Dempsey), Lexie works with Mercy West resident Dr. April Kepner (Sarah Drew) on a burglar, and the two get in several disagreements, leading Lexie to steal her diary. Dr. Alex Karev (Justin Chambers) and Adamson continuously argue over the course of treatment for a patient, leading the patient's daughter to yell at them in disbelief. Angry about the revelation that Percy (who later apologized saying that they can be friends outside the hospital, but not inside) was using her, Stevens accidentally administers the wrong dialysis to a patient, making her an unviable candidate for the kidney transplant she was scheduled to receive. After arguing over surgical cases for the entirety of the day, Yang comes to the realization that she needs a cardiothoracic surgeon to work at the hospital. After being mistreated by Kepner, Lexie begins to mock her about what is written in her diary, thus ruining her emotionally, but subsequently apologizes. Dr. Arizona Robbins (Jessica Capshaw), Torres' girlfriend, talks to Carlos, and convinces him to accept his daughter's sexuality. Having found out about Stevens' mistake, Dr. Miranda Bailey (Chandra Wilson) reprimands her reports her to the chief of surgery Dr. Richard Webber (James Pickens, Jr.). Webber asks Stevens to come into her office, and he fires her from the staff, noting that Hunt, Shepherd, and Karev had concerns with her coming back to work so early. Stevens departs, writing Karev a Dear John letter, causing him to cry in front of Meredith and Yang.
Grey's Anatomy Grey's Anatomy follows the lives of surgical interns and residents at the fictional Grey-Sloan Memorial Hospital (formerly Seattle Grace Hospital, Season 1–6, Seattle Grace Mercy West Hospital, Season 6–9, and then Grey-Sloan Memorial Hospital, Season 9–present), as they gradually develop as seasoned doctors, with the help of their competent attending mentors and chief of surgery. Each installment, typically, begins with a voice-over narrative from Meredith Grey or a season regular, foreshadowing the theme of the episode.[79][80] Each season tends to represent the physicians' academic year, with each completed year qualifying the residents at a level higher in the surgical field.[81] The season will always end with a finale, typically related to a dramatic event such as a death or character departure.[82] Most installments revolve around the doctors' everyday lives as surgeons, but the show also emphasizes their personal, rather than professional, lives.[79] The series sets aside medical ethic concerns to focus on character development and relationships. Although the physicians treat the illnesses of their patients, often through complex surgeries, they display competitive spirit and seek praise.[83]
