Cristina receives a Harper - Avery Nomination, but as the majority of Grey Sloan Memorial Hospital is owned by the Harper Avery Foundation, Cristina does not win . Dr. Meredith Grey (Ellen Pompeo), with the help from Dr. Stephanie Edwards (Jerrika Hinton), is also busy at work with her research, a continuation of the research her mother, Dr. Ellis Grey (Kate Burton), conducted while she was still living . To do her research, she orders a 3 - D printer, which not only aids Meredith's research, but also helps Cristina and Shane with their conduits . Derek and Dr. Callie Torres (Sara Ramirez) teams up with the White House to work on a brain mapping project, a project that will identify which parts of the brain are responsible for different functions . Dr. Miranda Bailey (Chandra Wilson) is also at the helm of a project mapping out the human genome, a project that helps her save her bubble - boy patient, Braden . Alex accepts a job offer from Dr. Oliver Lebackes, a.k.a. Dr. "Butthole," to work at his private practice . </P> <P> While separated, Dr. Arizona Robbins (Jessica Capshaw) continues to sleep around, this time with Dr. Leah Murphy (Tessa Ferrer).

Dr. April Kepner (Sarah Drew) and Dr. Jackson Avery (Jesse Williams) surprise everyone when they elope during April and paramedic Matthew's (Justin Bruening) wedding . Issues arise when April realizes that her faith, and Jackson's lack of faith, is going to be a huge problem when raising their children . Jackson, after some time apart from April and finding out that she's pregnant, tells her that he wants to go to church with her and his family . </P> <P> After losing the Harper Avery Award, Cristina receives offers from many institutions asking her to speak about her research . One of those offers comes from a hospital in Zürich, Switzerland . Despite Dr. Webber's pleading Cristina to fight against the Harper Avery Foundation for not honoring her work, Cristina takes off to Switzerland where she unexpectedly reconnects with Dr. Preston Burke (Isaiah Washington), the owner of the hospital . Initially, Cristina believes that this is all a ploy to get her back in his life, but it's really only a job offer to take over Burke's hospital because he wants to step down and move his family closer to his wife's parents in Milan . After realizing that neither she nor any other doctor at Grey Sloan Memorial Hospital will ever win a Harper Avery Award because of the Foundation's ownership, she accepts a job offer from Dr. Burke . Owen supports her decision as he realizes no good could come from him asking her to stay, but requests her not to leave him until she has to leave him for good, following which, they both spend two weeks leading to her permanent departure together . </P>

Do callie and arizona get back together in season 10
