'Not pregnant, I still have a hostile uterus.' Meredith says as she turns to Christina who stares at the stick.

'Me neither, knew I couldn't be. Nothing grows in me, especially without permission.' Christina throws the stick in the bin and leaves the bathroom. Callie turns her stick and also sees the 'not pregnant' words and never has she felt so relived. Although wanting a child, she doesn't want one with Mark.

Turning to Lexie, they see that all the colour ha drained from her face. Callie reaches and grabs the stick and the word 'pregnant' adorns the stick. 'You're pregnant?' Callie asks. Lexie mutely shakes her head, disagreeing with what the test has said. Meredith throws another test at her, signalling for her to take the test again. It is possible that the tests can be inaccurate, a false positive. But it's usually the other way around. Callie and Meredith get as comfortable as they can in the bathroom as they wait for Lexie to return. Each in their own thoughts as they wonder if Lexie could be pregnant. When the second test turns positive, the stunned silence settles over the three surgeons.

'I need to go, away from this' as she gestures at the pregnancy test now in Callie's hand. Lexie quickly heads out of the bathroom, not bothering to look back.

'How is that even possible, our control is pregnant?' Meredith says.

'Oh, there is a bigger question, who's the father?' Callie asks as both Mark and Avery can lay claim to knocking up Lexie.

'What did you do Torres, I just saw Lexie and she looked upset.' Mark asks as he storms into the bathroom. Mark had spotted Lexie as she left the bathroom and noticed the distraught look on her face. He had seen the surgeons entering the bathroom and immediately jumped to the conclusion that Callie had somehow further upset Lexie. 'Haven't you done enough damage by telling her about us.' As Mark approaches Callie he finally spots the positive pregnancy test still in her hand. 'You're pregnant?'

Looking up, Callie glances at Meredith and can see her silently pleading with her to not tell Mark who is actually pregnant. Not being able to lie to Mark, she brushes past him and leaves him standing in the female resident's bathroom. Deciding that, for now, she'll protect Little Grey from Mark knowing that she's pregnant. Callie realises she needs to talk to Little Grey and get herself checked out to ensure that the test was accurate.

Callie finally tracks down Little Grey hours later sitting in front of the human resources department in the basement of the hospital.

'God Little Grey, this is the last place anyone will come and looking for you.' Realising that was her plan; Callie sits down in a sit next to her. Spotting a piece of paper in her hand, she takes it and reads it. Lexie had got her blood done to confirm that she is indeed pregnant. Running her blood under a Jane Doe, no one in the hospital is aware that she is pregnant.

'Mark spotted the positive test. He saw you run out of the bathroom and thought I was upsetting you. He entered the bathroom and saw me holding your positive test. He assumed it was mine and that you were upset because he had got me pregnant. I left before I blurted out the truth. But Lexie, Mark and Avery need to know the truth. I can't keep this a secret because if Mark lets out that I'm pregnant my relationship with Arizona will be over for good. I'm sorry, but you need to work out what you are going to do, and fast.'

'What am I going to do?' Lexie asks, trying to seek guidance from the older woman. 'I don't even know who the father is. And Mark always wanted a kid, but I never did. I'm still a resident, I don't want this baby. And I have no idea how Jackson would feel, we've just been fooling around.'

'I'll help you, you can talk to me any time. But this decision is yours and yours alone. It's your decision if you tell Mark and Avery. And it's your decision with what you do.' Leaving Lexie to her thoughts, Callie leaves as she has her own appointments to keep.

Sitting in the gynaecologist's chair, she confirms what the pregnancy test had already told her. Calliope Torres isn't pregnant.

'Your lateness is likely caused by the stress you are under at the moment. If you haven't been eating or sleeping properly, your body doesn't act normally which is what has caused you to miss your period. The scans show that you are clean, so if you haven't started in a couple of days. Come back, and I'll do more scans to see if there is another reason.'

'So, I'm definitely not pregnant?'

'Yes, Dr Torres, you are not pregnant.'

'Oh thank god, imagine how hard it would be to convince Arizona to take me back if I was pregnant with Mark's baby. I mean, seriously.' Callie exclaims, not really caring that she is oversharing with the stunned gynaecologist. 'I mean would you get back with your lady lover if she had got knocked up by her best friend, who is acting like a jerk at the moment.'

'I didn't understand half of what you just said Dr Torres, but I'm sure everything will turn out fine. I want you to make another appointment in a couple days so we can just re-confirm that there are no medical issues.'

For the first time in a while, a sense of calm settles over Callie as she closes the gynaecologist's door. Now all she needs is a plan to get Arizona back. Knowing that Meredith and Christina will help in this regard, she plans a girls night to devise the plan. As she heads back towards the ER where she was supposed to be, she becomes lost in thought. Still concerned that the lack of period may be a serious health concern, she doesn't spot Mark heading towards her, a scowl gracing his face.

'Where the hell have you been? We need to talk about the situation. You can't shut me out.' He reaches out and stops her in her tracks.

Not wanting to have another confrontation with Mark, Callie attempts to step around him, hoping that if she ignores him that he will take the hint and take a hike. Mark, being oblivious to anyone's feelings but his own, pushes on not caring that everyone surrounding them is listening to their conversation.

'That's my kid in there! So you had sure as hell better stop and listen to what I have to say about this Torres. I have rights!' Mark yells at Callie. Callie's eyes widen in shock that Mark can be so blatantly insensitive to anyone's feelings but her own. Realising that everyone in the hospital will soon think that she is pregnant with Mark's child, Callie looks around trying to find an escape. Any thoughts that Callie had about getting back with Arizona just went up in flames. A stunned silence settles over the surgeons and nurses surrounding the two arguing doctors.

Callie tries to stop Mark 'Mark, please…'

'No, you listen, that's my kid. So I get a say. You can't just shut me out. I'm the dad, the father and that's my fucking right' he screams at her gesturing wildly.

Callie heart then plummets to the ground when she spots Arizona in the crowd, her eyes welling up with tears. Needing to escape from this situation, Callie breaks into a run and heads out of the hospital, not looking back. If she had she would have seen a heartbroken blonde and a furious man whore who believed Callie was taken his child away from him.

A/N: So, if you haven't realised yet, I really hate Mark. So he's going to be the bad guy so sorry to those people that like him. And writing this chapter I realised that the timing for all this is a bit dodgy. So I apologise for that. Hopefully, you guys understand. And Lil, I was never going to have Callie pregnant, so have faith! And I have a plan for the final chapter (or maybe two) of this story. And tow updates in a day – whoop whoop!
