This Thursday on Grey's Anatomy, find out what happens after Derek's (Patrick Dempsey) coup d'état against Chief Webber! With his Dreamy new administration in place, he's ready to crack skulls at Seattle Grace! OK, maybe not, but that's kind of regime change that Alex (Justin Chambers) is hoping for.
In other Grey's news, Sloan (Eric Dane) is still punishing Little Grey (Chyler Leigh) for their mutual indiscretions and Mer (Ellen Pompeo) has daddy issues (more, again, still), while Cristina (Sandra Oh) and Teddy (Kim Raver) continue to tussle over Owen (Kevin McKidd).
Press play above to see McDreamy make his inaugural address as Chief of Surgery, and then click in for five more clips.
