Scene: Lexie and Mark in his hotel room, making out on his bed. He tries to get to the next base but she pushes him away.

Mark: What's wrong? (goes back in to kiss her)

Lexie: Wait, not tonight.

Mark: Why not?

Lexie: Because you haven't told Derek about us yet.

Mark: (Now mad) Do you remember the promise I made?

Lexie: Listen, if you're not serious about us then just say it?

Mark: Are we serious?

Lexie: I thought we were but you know I guess we're not. See you at work Doctor Sloan.

(Mark lies on the bed bewildered)

Mark: Can I have a word with you Grey?

Mark: Please, Doctor Grey.

Lexie: (To Sadie) Tell Yang I'll be back in a couple of minutes.

Mark pulls her into a closet and starts kissing her.

Mark: It's going to be more than a couple of minutes.

Lexie slaps him.

Mark: What did I do?

Lexie: No. No sex until you tell Derek.

Mark: Why do you think I would want to have sex with the girl who broke my penis?

Lexie: Then I guess we both win. I got to go.

Scene: Mark walking down the hall and sees Callie.

Mark: Callie! A word?

Callie: Yeah of course, why?

Callie: Oh you're over Grey now?

Mark: No, I think I actually might have some type of feelings for her.

Callie: Wow! Hold on to her.

Mark: She's refusing sex until I tell Derek about us.

Callie: She's a smart one isn't she, goes straight to the target area.

Mark: What should I do?

Callie: Don't ask me for romantic advice.

Mark: See you later.

Callie: See you later.

Scene: Joe's. Lexie's at the counter along with Callie.

Lexie: What's wrong with you?

Callie: I'm lonely. I mean everybody's found somebody but me. I mean even Mark has somebody.

Lexie: I see you look at Sadie.

Callie: Do you think she would even ever feel the same way?

Lexie: I don't know but taking a chance must be better than sitting here alone.

Callie: True Little Grey, so true.

(Mark and Derek walk in)

Lexie: Oh hey.

Derek: Hey Lexie.

Mark: Little Grey.

Lexie: Doctor Sloan.

(Derek looks on, they all sit down for a drink.)
