Meredith Grey is the show's central protagonist and narrator of most episodes. She begins the series as an intern and has since progressed along her medical career path. She went to the Geisel School of Medicine at Dartmouth College after sleeping around Europe with her former best friend, Sadie. She is best friends with Cristina Yang. Following a long romance, she marries neurosurgeon Derek Shepherd. On the day of the shooting in Season 6, she discovers that she is pregnant, but she miscarries the baby due to stress that same day. She later learns that she has a "hostile uterus" and starts taking fertility shots. When they are unsuccessful, Meredith and Derek adopt Zola, a surgical African orphan. In Season 9, following the plane crash that killed her younger sister, Lexie Grey, Meredith becomes an attending general surgeon. She has earned the nickname "Medusa" from her interns and residents. Bailey is born in the Season 9 finale; she gives birth to him by C-section and has major abdominal surgery following a fall. In the Season 10 finale, she says goodbye to Cristina as Cristina leaves for Zurich to take Burke's hospital; before they say goodbye, Cristina reminds Meredith that she should not let Derek's career hinder her own. In Season 11, Meredith struggles with keeping her marriage afloat after Derek decides to work for the president in DC and learning that she has another half-sister, Maggie Pierce. After Derek is killed at the end of Season 11, Meredith escapes to California for a year, where she gives birth to their daughter, whom she names Ellis after her late mother. In Season 12, Meredith returns to Seattle and is named Chief of General Surgery by the newly appointed Chief of Surgery, Miranda Bailey. Meredith tries moving on by dating William Thorpe, a surgeon from another hospital, but has trouble forgetting about Derek. She can finally take the next step with Nathan Riggs, and the two begin a relationship after months of Nathan pursuing Meredith. Still, the romance comes to an end after Nathan's missing fiancée, Megan, is found. Meredith wins a Catherine Fox Award in Season 14 after performing a ground-breaking abdominal wall transplant on Megan. In Season 15, she begins a relationship with Andrew DeLuca after sharing a kiss at Alex and Jo's wedding. She is fired from the hospital after Season 15 for committing insurance fraud. In Season 16, she is forced to do community service while her medical license status hangs in the air; after a hearing, she can keep her license and is rehired by Grey Sloan. On her first day back, she meets Cormac Hayes, the new Chief of Pediatrics, whom she grows closer to as they bond over their shared loss of a spouse. During this time, she and Andrew also break up after Meredith confronts him over his developing signs of mania. In Season 17, Meredith tests positive for COVID-19, and while she battles for her life, she falls in and out of consciousness as she dreams of Derek, George, Andrew, Lexie and Mark. She eventually recovers and begins operating again, as well as assumes the position as Director of the Residency Program.

Izzie left Seattle Grace and started anew on a farm in Kansas. Izzie later divorced Alex and kept the fertilized embryos, which she used to have the twins.
