Meredith goes to see Derek at his trailer. He tells her he can't get over the fact that when she fell in the water during the ferry tragedy, she didn't swim. Ever since then, he's been trying to breathe for her, he says and he doesn't know if he can keep doing that. She says she should go and Derek doesn't stop her.
Addison asks Mark out for a drink so they can talk, but he lies and says he slept with someone, so the bet is off. We’re actually kinda moved by how hurt McSteamy is now that he realizes he and Addison will never be together. Later, Addison finds Alex studying and volunteers to quiz him. He tells her she's not his girlfriend and that he's busy. Now we feel bad for Addison. Grey’s can be such a roller coaster ride sometimes.
