I Choose You (Grey's Anatomy)

"I Choose You" is the third episode of the twelfth season of the American television medical drama Grey's Anatomy, and the 248th episode overall. Written by William Harper and directed by Rob Corn, the episode aired on the American Broadcasting Company (ABC) in the United States on October 8, 2015.

The episode focuses on Jo Wilson (Camilla Luddington) grappling with the uncertainty of her relationship with Alex Karev (Justin Chambers) after discovering a possible connection to his former partner, Izzie Stevens (Katherine Heigl), leading her to confide in her close friend, Stephanie Edwards (Jerrika Hinton).
