(Meredith enters the lobby where Derek is waiting for her) 

Derek: Long day. 

Meredith: Yeah. 

Derek: Somewhere out this is a steak with your name on it and maybe a bottle of wine. 

Meredith:  This is why I keep you around. 

Derek: So we need to talk . 

Meredith: Wine first, talk later. 

Derek: You trying to, uh, get me drunk so you can take advantage of me? 

Meredith: I think I like this rules thing. 

Derek: Me too. 

(Derek helps her fix her coat and they turn to leave. A stunning red headed woman is standing there and Derek is wide eyed) 

Derek: (Turning to Meredith) Meredith, I am so sorry. 

(The woman walks over) 

Derek: Addison. 

Derek:  What are you doing here? 

Addison: Well, you'd know if you'd bothered to return any one of my phone calls. 

Addison: Hi. I'm Addison Shepherd. 

(They shake hands) 

Meredith: Shepherd? 

Addison: And you must be the woman who's been screwing my husband. 

(Meredith looks at Addison and then at Derek)
