"Fear (Of the Unknown)" is the twenty-fourth episode and the season finale of the tenth season of the American television medical drama Grey's Anatomy, and is the 220th episode overall. It aired on May 15, 2014, on ABC in the United States. The episode was written by Shonda Rhimes and William Harper and directed by Tony Phelan. On its initial airing, it was watched by 8.92 million viewers.^[1] The episode marked the departure of one of the lead characters, Cristina Yang, played by Sandra Oh since the inception of the series in 2005. The episode focuses on Yang as she prepares to say her goodbyes to the doctors at Grey-Sloan Memorial hospital, including her "person" Meredith Grey (Ellen Pompeo), her long-time friend and Meredith's husband Derek Shepherd (Patrick Dempsey) and her love-interest Owen Hunt (Kevin McKidd) and leave for Zürich for her new job at the Klausman Institute for Medical Research. The episode received universal acclaim with widespread praise directed towards Oh's performance and the send-off for her character.

Amidst Yang's departure a catastrophe occurs at a nearby mall bringing loads of patients to Grey-Sloan. Derek asks Meredith to move to Washington, D.C. with her for his new job. Callie Torres (Sara Ramirez) and Arizona Robbins (Jessica Capshaw) consider having a surrogate mother carry their child while April Kepner (Sarah Drew) is nervous about raising her own child with Jackson Avery (Jesse Williams). Miranda Bailey (Chandra Wilson) is nominated for a position at the Hospital Board to replace Cristina, who instead left the seat for Alex Karev (Justin Chambers). Also, Leah Murphy (Tessa Ferrer) is fired from her job, Shane Ross (Gaius Charles) quits his residency at Grey-Sloan to accompany Yang to Zürich as her student and Richard Webber (James Pickens Jr.) meets with Maggie Pierce (Kelly McCreary), and finds out that her birth mother was Ellis Grey (Kate Burton).

This episode marks the final appearance of Sandra Oh as Cristina Yang and Gaius Charles as Shane Ross. It is also the final appearance of Tessa Ferrer as Leah Murphy as a series-regular.
