Grey's Anatomy, Season 9

Lizzie:
You know we're family, right? There was no wedding, Meredith. You adopted a baby and you never invited us to come meet her. You never accepted our invitation to come see us. All we got was a couple of pictures via e-mail. You know, my kids were so excited that for months, they walked around telling every African-American person they saw that we have a brown baby in the family? A year later, they kind of think I made the whole thing up.

Meredith:
I'm sorry. It's just, you know, with everything that's been going on––

Lizzie:
No, I get that we're all busy, but you're not shy about asking me for a couple of body parts, and now you want me to cover your tracks with Derek?

Meredith:
If you feel like it's inappropriate––

Lizzie:
No, it's what sisters ask sisters to do. We cover each other's asses. Look, if you want to be a sister, I am delighted, but then act like one.

Meredith:
My version of family isn't like your version. You guys give each other crap and then you laugh about it. You'd walk through fire for each other. Greys are not like that.
