Scene: Lexie and Izzie are both in the waiting room.

Lexie: What are you doing here?

Izzie: Patient. Why are you here?

Lexie: Oh, no! It's not for me. This is Mark's baby!

Izzie: Good.

Lexie: Good.

Lady at Counter: Ladies your results are here.

(They both run to the Counter.)

(Lexie's baby is positive, while Izzie's is negative., it wasn't Alex's.

Izzie: (Thinks.) Oh no! What am I supposed to do now. Maybe it's wrong. It has to be Alex's. She had made up the whole Denny thing. Hadn't she?

_____________________________________________________________________________________

Lexie: Have you seen Alex?

George: No, why?

Lexie: It's his baby George. It's Alex's. I don't know what to do?

George: Don't tell him.

Lexie: I have to.

George: Are you going to tell Mark?

Lexie: I don't know. How did this happen to me?

_____________________________________________________________________________________

Mark: Lexie what are you doing tonight? (He sees that Lexie has been crying. He hugs her.)

Mark: It's okay. It's okay. What happened?

Lexie: Nothing. It's all these hormones.

Mark: That's okay. I thought tonight we could go to dinner and have some fun.

Lexie: (Still sobbing.) Alright.

Mark: Alright. I'll see you tonight.

_____________________________________________________________________________________

Lexie: Alex, it's yours. The baby's yours.

Alex: Wow! I'm so happy. I'm going to be a father.

Lexie: But you love Izzie and I love Mark.

Alex: We can still raise this baby. Tell Mark.

Lexie: I can't believe I even convinced you to do this test.

Alex: If Mark really loves you he'll still marry you.

Scene: Lexie and Mark are at a fancy dinner.

Mark: What's wrong with you? You seemed depressed.

Lexie: No, no. I'm fine, really. I'm sorry if I'm bringing the mood down. It's just that nothing makes a bad day worse than morning sickness.

Mark: Well, do you want desert?

Lexie: Of course, I could never have enough food.

Mark: Alright. Waiter, can we get the cheesecake.

Lexie: So how was your day?

Mark: Pretty Good.

(The waiter comes with the cake.)

Mark: Ever since the day I met you I've been crazy about you. No wait that's a lie. At first you were pretty annoying. But I did realize how much I liked you and since then I've never doubted that you were the one for me.

Lexie: Ouch! I think I bit on something hard in my cake. (She pulls out the ring.) Oh, so romantic.

Mark: I know it's cheesy (no pun intended) but I wanted to make it special. I just love you so much.

(Gets down on one knee.) Lexie Grey, will you be my wife?

Lexie: No.

Mark: Lexie, that's not a very funny joke.

Lexie: It's not a joke. I love you I do. But I need to tell you something. So you should probably sit down.

Mark: What?

Lexie: Well, do you remember the night that Derek said he was going to propose?

Mark: Yeah. Why?

Lexie: Well, I was really mad at you because you didn't tell him. So I got really drunk and Alex came by.

Mark: Are you saying what I think you're saying?

Lexie: And we were both upset and very drunk and we slept together. It didn't mean anything. I was just letting loose some steam. I'm so sorry.

Mark: Is it my baby?

Lexie: I wasn't sure and then yesterday I asked Alex for a sample and it's his. It's Alex's baby.

Mark: I'm done.

Lexie: I'm sorry, Mark. I love you I really do.

Mark: You made me believe it was my baby.

Lexie: I really wish it was.

Mark: I'm leaving. Go be with Alex for all I care.

The lady at the counter goes through her records and makes a startling discovery. She gave the wrong test results to Lexie and Izzie. Lexie's were negative while Izzie's was positive.

(She decides to call Lexie.)

Lady at the Counter: Hello. Doctor Grey? Is that you?

Lexie: (sobbing) Yes. It's me. Who is this?

Lady at the Counter: It's Maureen from the Ob- Gyn Clinic. I just wanted to tell you that the results were switched. The sample wasn't your patient's father.

Lexie: Thank You. (Absent mindedly hangs up the phone.) Seriously? Seriously? Seriously? She couldn't have called five minutes ago? Seriously?

(Izzie receives the same call and is ecstatic. She can't wait to tell Alex.)
