George and Bailey are helping various people at the scene. Cristina, Burke, Derek, Mark, and the chief are all at the hospital waiting for the patients. Burke tells Derek that he and Cristina got engaged, and Mark overhears the news. Mark tells the chief who congratulates Cristina. She gets mad because she wanted to tell Meredith first. Burke tells her that she had all day to tell her and she didn't. Cristina walks away, reminding Burke that they are expecting the first arrivals from the scene any minute.
