MEREDITH: "I just agreed to have dinner at my father’s house. Tonight."
DEREK: "Oh."
MEREDITH: "And, Cristina slept with Colin Marlow."
DEREK: "Marlow? Transplant Marlow?"
MEREDITH: "They had a thing when she was a student.
DEREK: "He slept with Christina?"
MEREDITH: "Derek!"
DEREK: "Oh, right, sorry, okay. Um... have dinner at your house. It’s your place, I’ll come. I’ll be your wingman. It’ll be fun. Okay, it won’t be fun. It’ll be fine. They’re your family."
MEREDITH: "Why does everyone assume that?"
DEREK: "Because you deserve to have a family. Even if you don’t like them."
