Cristina : As far as a I can tell...severe abandonment issues.
Meredith : That's crap. Psych is crap. Issues.
Cristina : It's in the book. The book said it not me. Have you consider maybe you and Derek should stop having break-up sex?
Meredith : The more available he gets...the more I pull away.
Cristina : What do you mean?
Meredith : Nothing. It's a Derek thing.
