Addison: Alex, I'm leaving
Alex: What? You're leaving?
Addison: I was offered a job, a friend, in Los Angles, LA General. They needed someone in Neonatal and it turns out that I am their girl.
Alex: You didn't tell me.
Addison: Alex, I am sorry, it was sudden, I was on the phone with a friend. We were talking, about New York and Seattle, and how I wished I could just get away, and he said there was an opening, so I said okay and... next week, it's my last..
Alex: So what does that make us? I just put myself out there, for what, for nothing? So you could tell me off this time, instead of the other way around?
Addison: You told me you were not interested, a long time ago, you told me that! And now, now you suddenly change your mind, now you want a chance? It doesn't work like this. I am trying so hard to put my past behind me, and you can't expect me to just stay... I can't, not now, not for all the wrong reasons.
Alex: Fine, whatever
ONE WEEK LATER
The Chief, while disappointed that Addison, the woman who he mentored for so many years, was leaving. He nonetheless was happy for her, and while short notice, was able to pull together a small going away party for her.
Derek: Addi, you're really leaving?
Addison: Yeah, I am. I should have done this along time ago Derek, but, it never seemed right.
Derek: It's time now though? James offered you the position at LA General, and its time for you to take it?
Addison: Yeah... Its time for me to leave, you deserve Seattle, and I owe myself another chance, I need to wake up some place different, at least for a while...
Derek: Addison, I want you to be happy more than anything else, and I want you to have that chance, to start over. For eleven years, you were the love of my life, and not a day goes by that I don't think about that, and if this is what it takes, for you to be happy, then I support you.
Addison: Thanks...
Derek(smiles): No, Problem...
Addison: I guess this is goodbye ... for good this time...
Derek: For good this time...
Callie: ADDISON MONTGOMERY!
Addison(startled): Callie?
Callie: You are leaving! And you didn't even tell me.
Addison: I'm sorry Callie, it was a sudden thing and I...
Callie: Hey, its fine, I'm just kidding. Although I don't know what I am going to do with out you. I need your help, defeating the evil Izzie Stevens.
Addison: For some reason, I don't think you need my help to take her down...(laughs)
Callie: You are right, but, I'm going to miss you. Who am I going to eat lunch with?
Addison: Well... there's that Psych resident, Sydney... Heron..? (giggles)
Callie: Oh god... Addison, really..?
Addison: I'll call you when I leave.
Callie: You'd better!... Okay, so this is bye. (sad face)
Addison: Yeah, Okay.. bye (sad face)
Addison: I will vist though... tons!
Callie: Oh, like you even had a choice not too!
they hug and blah blah
Mark: Were you going to leave without saying goodbye?
Addison: I was considering it..
Mark: Addi, why? Why can't you stay here? If you want to leave, leave with me, we can go back to New York together.
Addison: The New York part bothers me, but the "together" part pisses me off.
Addison: Mark, we tried, I tried, and I like to think you tried, and it just couldn't happen, it didn't work. And there's a lot of different reasons for that.
Mark: You used to love me...
Addison: I did Mark, I fell out of love with my husband, and I fell head over heels in love with you. But things change. Could it have worked between us, I really think it could have, but we both have so much baggage. Maybe if you hadn't been Derek's best friend... or maybe if we gave it another try someplace that wasn't Seattle, and wasn't New York. Those are all maybe's Mark, and as far as I'm concerned, that's all they'll ever be, I'm sorry.
Mark: I only wish I had met you before Derek had...
Addison: There were times when I wished that too... but... I did love my husband for a very long time, and its hard to forget that.
Mark: I don't know what I'm going to do with out you. Maybe I'll stay out here, start a private practice...
Addison: You would leave Seattle Grace?
Mark: I'm no good at the teaching thing, I only tolerated it because of you... and you're gone so...
Addison: Have a good life Mark... bye
Mark: Addison... you will always be my baby, and I will always love you...
Addison: Not always Mark. You will find someone, someone who doesn't take your crap sitting down, and someone who will keep you on your toes. You will find some one who you love more than me.
Mark: Never, not possible...
Addison: Bye Mark
Mark: Bye Addison...
