Question: who becomes chief of surgery after owen hunt

title: Owen Hunt
text: `` I was doing a movie off and on for three months , and it was my son 's birthday , so I managed to land back in LA . around 2 p.m. Then I got a call from my agent , saying , `` You have to turn back around because Shonda wants to meet you for this role on Grey 's . '' I was like , `` I 'd love to meet her , but I ca n't . Can we do tomorrow ? '' And they 're family - friendly , so they were really understanding . As soon as I heard the pitch for the character , I was sold on it . It 's a different energy and a different viewpoint . I thought it was an important story to tell , especially on a prime - time TV show . To get in there and get your hands dirty and explore what trauma surgery is like in war zones and what it 's like to rehabilitate yourself to civilian life . It 's not just a new doctor showing up . It 's exploring how hard it is to reintegrate yourself back into the real world after being in the war zone for three tours . ''
