Callie and Arizona buy a new house that'll be theirs together, with Arizona wanting to give their relationship one last new start . Chief Hunt begins to ride Ross aggressively in the ER, not just after the botched surgery with Jimmy but (according to an accusative Webber) because he has learned that Ross had been sleeping with Cristina . Alex's emotional plea to Jo turns out to, in his mind, have been a marriage proposal; Jo turns him down, claiming they're not ready, but continues to stand by him when Jimmy passes away . Bailey and Ben start talking and working through his arrival . She tells him that she's worried that he'll be at home waiting on her just like Tucker used to do, and he resumes his internship...at Grey Sloan .

Derek has to tell Callie that they can't continue with their research because of the guidelines in his contract with his colleagues at the White House . As if that's not enough, Callie learns the HR complaint was filed by Leah against her, as Leah felt that she was cheated out of a learning opportunity and needed to stand up for herself and others .

Time is quickly passing as the two get married, move in together, get a dog, have a baby, await the birth of their second child, and see Ross win the Harper Avery Award for Cristina's trial that she quit on to take care of her family . The second universe begins when Cristina comes back to reality and her patient says he doesn't want to be taken off the ventilator . This once again sends Cristina into Owen's arms, but this time, she's happy . However, the stipulation that they will never have kids still remains, which Owen initially accepts . They continue to have their on - again, off - again relationship which drives Owen to drinking more than he should, putting himself and his patients in grave danger . Cristina tells him it's over for good, and she goes on to win the Harper Avery Award for four straight years . Once again, Cristina comes back to reality . This time, her patient decides to be taken off the ventilator; however, she's able to save Jackson from injuring his hand, and her hesitancy to approach Owen allows Meredith to approach her about a patient, which allows Owen to get on the elevator before she can greet him . </Td> </Tr> <Tr> <Th> 214 </Th> <Td> 18 </Td> <Td> "You Be Illin"' </Td> <Td> Nicole Rubio </Td> <Td> Zoanne Clack </Td> <Td> April 3, 2014 (2014 - 04 - 03) </Td> <Td> 8.28 </Td> </Tr> <Tr> <Td_colspan="7"> A virus breaks out at Grey Sloan Memorial Hospital .
