The fourth and final season of Killing Eve begins airing Feb. 27 on BBC America and we have to admit, we're going to miss the delicious cat-and-mouse game played out between former MI6 agent Eve Polastri (Sandra Oh) and her psychopathic nemesis, the assassin Villanelle (Jodie Comer). Framed against a backdrop of revolving sexy European locales, the barely resolved, psycho-sexual subtext between good Eve and bad Villanelle fed us on so many levels.
