When Meredith is annoyed that Derek isn't visiting, she goes to Derek's trailer and finds him fresh from the shower, with a woman on his bed! She assumes they are in a relationship but it is just his sister Nancy. Meredith leaves before Derek can explain.

She came to Seattle to check up on him since he's skipped the last few family holidays. She dislikes Meredith and repeatedly called her the slutty intern and, much to Derek's dismay, warmly embraces Mark and Addison.

She continues to hint to Derek to forgive Addison for her one-night stand with Mark, eventually Derek breaks and tells her that they carried on with their relationship for two months after he left. She then accepts this and goes home happily, accepting his decision. However before she goes, she gives him some advice. Nancy advises him that maybe he needs a little time alone, to sort things out. To commit to himself, rather than run circles around all the women in his life and Derek subsequently tells Meredith he does need a little time to himself, and she agrees.
