DISCLAIMER: I DON'T OWN GREY'S ANATOMY, I wish I did.

Meredith woke up with a pounding headache. She looked over at Derek who was still sleeping. She wanted to shove him off the bed onto the floor. She was mad about Lynn. She really didn't think he was going to stand up for her. Why would he? She sat up and the room began spinning. Why the hell did she go to Joe's? She slowly threw her legs over the bed and walked to the bathroom, clinging to the wall. She made her way to her destination, taking a seat on the floor. Why did she not eat dinner? She began vomiting into the toilet. This was going to be a wonderful day. It was Derek's birthday. Now she had to go home and be verbally bashed, and keep a smile on her face. At least Lynn was going home tomorrow. What about next time? There would be a next time. Lynn would return on her broom and set the town on fire. Meredith heard Derek get up. She wasn't going to acknowledge him.

Derek: Morning. Don't you look beautiful, hugging the porcelain god?

Meredith: Go to hell.

Derek: Grouchy! I need to pee.

Meredith: Well, I am using this toilet. Take your ass outside and use a tree. You are a man, at least you were, until your mom came to town. (She slams the tiny bathroom door shut.)

Derek: (Walks away.) You know, you could be nice to me! Today is my birthday.

Meredith: (Less than happily.) Well, happy freaking birthday. (She hears the door shut. She begins retching once again. Derek comes back in.)

Derek: You should really give up tequila. (He smiles.)

Meredith: I like tequila.

Derek: Every time you drink it, you suffer the next day.

Meredith: I like to suffer!

Derek: If that were true, you would be at home right now.

Meredith: Screw you!

Derek: Please?

Meredith: Shut up!

Derek: You are so cute when you are mad.

Meredith: Why do you have to be so goddamn nice?

Derek: You know you love me. Here. It's Phenegrin. I think you need it.

Meredith: Thanks.

Derek: You want breakfast?

Meredith: Do I look like I want breakfast? I need you to take me to get my car.

Derek: OK. We'll go after I'm done eating. I have to get back to 'your house'. I told Mom I had to go to the hospital.

Meredith: It's your house too. What did she plan? For your birthday.

Derek: She is making dinner. She is making a cake. It's pathetic, I know. She makes fried chicken. Every year, my whole life, it's the same thing.

Meredith: I have the day off. After I get my car, I'll come home. I'm doing it for you.

Derek: I appreciate it.

Meredith: I hope so.

Meredith's nausea was going away. They drove to the hospital in complete silence. Derek's birthday wasn't even special anymore. She didn't even care if he like his present, she didn't care if he had a good time. She resented him right now. She knew things would go back to normal as soon as Lynn left. Meredith drove home in silence. When she pulled into the garage, she sat in the car for a few minutes. Derek was already there. She had to go in. Maybe she should leave the car run. Then she wouldn't have to worry about ever seeing Lynn again. She wasn't that unhappy. She could do this. Meredith was in shock when she walked in. Lynn had moved some of the furniture around.

Lynn: Hello, Meredith. I'm so glad you don't have to work today!

Meredith: Me too. I see you moved the furniture.

Lynn: Yes- I didn't like it the way it was.

Meredith: Oh. Well, I have to go take a shower. I wanted to get home, so I didn't take one at the hospital. (Derek passes Meredith on the stairs, she doesn't say a word.)

Lynn: That girl is a tart. So miserable.

Derek: She is not miserable!

Lynn: You know she is having an affair on you, right. I have proof.

Derek: Meredith is NOT having and affair. I don't care if you have video of her with another man. She is not having an affair. Not Meredith.

Lynn: She is all wrong for you Derek.

Derek: Damn-it mom! (His pager goes off.) Shit! It's the hospital.

Lynn: Derek- language!

Derek: I will be back. (He leaves. Meredith comes down.)

Meredith: Where is Derek going?

Lynn: He got paged.

Meredith: Great.

Lynn: Derek is good to you. I see everything you have. Are you in it for the money?

Meredith: No, I am not! Besides, how the hell do you know that I don't have money.

Lynn: It's pretty obvious. Look at how you present yourself.

Meredith: Oh, so I don't appear rich, therefore I am not?

Lynn: You lack refinement. My son deserves the best. Addison would have been great with him.

Meredith: Addison? Addison is nothing like Derek. Not to mention she is happy with Mark!

Lynn: You just aren't what I had always imagined.

Meredith: Well, I am obviously what Derek imagined!

Lynn: Well...What about children? Are you planning on having children?

Meredith: I don't know.

Lynn: Well, if you do marry my son, I want grandchildren.

Meredith: I don't know if I want children.

Lynn: What kind of person doesn't want children? Are you infertile?

Meredith: I don't think that is any of your business! I do not want to talk about that. (Her cellphone rang. It was Cristina. She kept her on the phone for an hour. Lynn kept checking in, and Meredith would glare at her. Finally Meredith made her way to the kitchen where is was making Derek's cake.)

Lynn: Have you ever thought about breast augmentation?

Meredith: What?!

Lynn: Derek had always liked larger breasts. If you want to keep him, you should probably do something about that!

Meredith: Oh really? Well I do not think Derek has a problem with my breasts. In fact he really likes them. Putting his hands on them. His mouth. Oh, and you should hear him screaming my name. The things that man does to me. Wow. I have to say, he's good. We are good. He can't get enough of me. Last night was, wow. Where do you think he disappeared to last night? The man can't keep his hands off me.

Lynn: (Huffs.) Well. You really do lack class!

Meredith: Sex in the car. Sex in the shower. Sex at work. Sex on this countertop.

Lynn: You are disgusting! Why are you telling me this?

Meredith: Sex on the couch. Shit, I even think we did in in your bed, last week. Nope it was right after I changed the sheets for you.

Lynn: You are a bitch.

Meredith: As are you. He is MINE. I love him. I want to spend the rest of my life with him. I WILL spend the rest of my life with him. So get over it. You may not have to like me, but you damn well will respect me. I am not going anywhere. (She walks upstairs. Derek gets back home.)

Derek: Where's Mer?

Lynn: She is upstairs. You are not staying with her. She is a bitch. I will not have my son with a no good, cheating whore!

Derek: That is the last straw! (He storms upstairs, into the guest room. He begins packing his mother's things.)

Lynn: Wha- What are you doing?

Derek: You are leaving. (He begins walking downstairs with her bags. Lynn follows him and Meredith is behind her.)

Lynn: What are you talking about?

Derek: You are not staying here! I love her. I love Meredith.

Lynn: How can you love someone who is cheating on you?

Derek: Meredith is not cheating on me! (He calls a cab.) Meredith is the love of my life! This is her goddamn house. I live in a fucking trailer.

Lynn: Oh my God! Are you gambling? Is it drugs?

Derek: I bought land. I live in an Air-stream trailer. Meredith is not cheating on me. I assume you saw the pictures of she and John. Her husband. He was killed about two months ago. She was good enough to go along with the lie I made up. She wanted me to be happy. She packed all of his stuff away for me. She has sacrificed everything for me. I love her. If I have to choose between you and her. I choose her. I will not stand here and let you treat her like shit! I want you out. I made reservations at the hotel for the night. You will not be staying here!

Lynn: Well, finally!

Meredith and Derek: What?!

Lynn: Son, you have brought girls home year after year. Each time I treated them terribly. You let me. The things I have said. My god. I am lucky one of them didn't kill me. Your father never stood up for me. His mother treated me horribly. I suffered through our whole marriage. I know she was your grandmother, but I could not wait for that miserable bitch to die. Your father was a coward of a man. I will be damned if my son will be.

Derek: What are you saying?

Lynn: I want you to be happy. You never stood up for any of the other girls. I knew they didn't mean anything. Meredith, you love her. You stood up for her. Meredith, honey, I didn't mean the things I said. I like you. You are just like me. The real me. I got so caught up with who Derek's father wanted me to be, that I lost myself along the way. I was the model wife, and mother. You are a spitfire. You are strong. Do not change for anyone.

Meredith: This was a test?

Lynn: Yes.

Meredith: What the fuck is wrong with you?

Derek: Mom! This is unbelievable. Even for you!

Lynn: I had to know that you would be happy.

Derek: I can make that decision for myself. I don't need you to do it for me!

Lynn: You are my son. I love you.

Derek: You need to leave.

Lynn: What?

Derek: Even if you didn't mean it, you hurt us. I will not stand for it. I can't deal with you right now. It's my birthday. I want to spend it with Meredith. I need you to leave.

Lynn: Derek! I'm sorry.

Derek: I am NOT the one you should be apologizing to!

Lynn: Meredith. I am so sorry. I thought I was doing a good thing! I would be honored to have you as a daughter-in-law. You have a good heart, and you love my son. That is all that matters.

Derek: Mom, your cab is here.

Lynn: Happy Birthday, son. (She kisses him.)

Derek: Thank you, mom.

Lynn: Thank you Meredith. (She hugs her.) I have never seen my son so happy. He lights up when you walk in a room. Thank you. (She grabs her bags and walks out.)

Meredith: I love you Derek. Thank you. It means a lot to me.

Derek: I love you. I am not going to lose you. You mean too much.

Meredith spent a lot of time thinking and decided that she would give Lynn a second chance. She loved Derek and she didn't want there to be a strain between the three of them. She convinced Derek that they could all have a nice dinner at the hotel. She wanted everything to be peaceful. They got ready and drove to the hotel.

Lynn: Meredith, you look beautiful. Happy Birthday, Derek.

Meredith: Thank you. (They all sit down.)

Lynn: Well, so much for tradition.

Meredith: Sometimes traditions are made to be changed.

Lynn: Well, I hope that you are one that will be around for a long time. So how long were you married?

Meredith: 9 years. He was my childhood sweetheart.

Lynn: That is nice.

Meredith: It was sad, but that was the way it was meant to be.

Lynn: I'm so sorry for your loss.

Meredith: Now I have Derek. He means the world to me.

Derek: Do I really?

Meredith: Yes, you do!

Lynn: You are so happy together.

Derek: Yes, we are. I knew she was the one for me, the minute I saw her. I had never felt that way before.

Meredith: I need to go to the ladies room.

Lynn: I'm so happy for you, son.

Derek: She's the one. The one I am going to spend the rest of my life with.
