If there's an episode that prepped the Golden Globe winner for a thriller series like Killing Eve, it might be this arc where Cristina and other Seattle Grace surgeons are stranded after a plane crash. As her friends are in grave conditions, Cristina alters between slapping sense into her fellow surgeons and screaming for her lost shoe. Admittedly, her missing footwear bit brings a lightness to the situation, but it also highlights her desperate, crumbling mental state spot-on.
