Derek Shepherd quit as chief in With You I’m Born Again after a tenure of less than a year. Richard Webber became chief again for a year until he resigned, again, in Take the Lead. He nominated Owen Hunt to replace him.

Why does Derek quit as Chief?

Derek coped with the traumatic experience by speeding. He was arrested multiple times for speeding, which led to Meredith leaving him in jail overnight. He quit his job as Chief of Surgery, having intended to do so for some time as he realized he preferred to be in the O.R. instead of doing administrative work.

Does Derek break up with Meredith to be Chief?

Meredith, Cristina, Izzie, and Alex are new residents and have their own interns, including George, who failed his intern exam, and Lexie Grey, Meredith’s half-sister. Meredith and Derek break up but continue having breakup sex. Erica Hahn is hired as Chief of Cardiothoracic Surgery, replacing Preston Burke.
