Season 4 | Episode 14 | Aired 05/8/08
Derek and Meredith are perfectly in sync during Darren’s surgery. Derek offers to stay with Meredith to monitor their patient throughout the evening. But Meredith tells him to go home with Rose. Darren crashes later that night and dies. Derek brings Meredith a bottle of champagne. They are going to open it when they finally save a patient with their clinical trial. They’ll also make a toast to all the ones they lost.
Bailey manages to smooth things over between Mark and the nurses. Of course, she does label McSteamy a “man whore” in the process. Sloan feels bad about that but Derek seems to feel worse. He admits to Mark that he finally slept with Rose…but was thinking about Meredith the whole time.
