She was tired. They had been married for three years today and she was tired. She couldn't even keep her eyes open. She had been ill for two weeks now and unable to seek comfort in her wife because her wife was the top Pediatric surgeon in the country and had to attend back to back conferences. Her wife was due to fly in, five hours from now and she was tired. Lying down usually helped her get rid of the churning in her stomach but this time it failed miserably. She was tired, but unable to sleep and lying in an on-call room waiting for something to happen. She hoped it would be sleep to overwhelm her, instead it was the door to swing open violently and a fierce voice broke through her bubble of serenity.

"Torres."

"Derek? What's the matter?" She asked into her pillow.

"Is it Mark's?"

"Huh?" Her mind was cloudy. Three weeks away from Arizona – that's all it took for her to lose it completely. That's what she thought, because this was not McDreamy…. This was a Derek who was angry and unkept and asking strange questions. It was McAss that she'd heard of from Cristina. No her mind told her that she must be somewhere between awake and asleep.

"The baby? Is it Marks?"

"Huh?" What baby? Is there another Sloan Sloan out there? Teddy would be devastated especially because it took them so long to build their friendship before they finally got back together. With that last thought her stomach churched once more and she lost all concentration. She let out a pained "Hmm.", then snuggled closer into her pillow.

"It is his?" He steps closer and asks more sharply.

"Is what, who's?" She snapped. She was sick. She was tired. She was missing the most important person in her life. She didn't need whatever Derek was doing.

"The baby, your baby…. Is it Marks?"

"What baby. I don't have a baby." She was confused, the haze of non-sleep not allowing her to process the words.

"I've seen you throw up the same time everyday for two weeks." He was starting to get frustrated by her avoidance. He'd seen the signs and spent the better part of a week debating whether or not to confront her, but Arizona had spoken to him, she had seen him when no one would or could see. She stepped in when others may have thought it was none of their business and let it slide. If the blonde had 'let it slide' he was certain that his recovery would have resembled something more like the weeks before his proposal to Meredith. He couldn't let this slide either, not when the woman he'd grown so fond of could be hurt just like he was.

"I have a stomach bug." He almost scoffed at the idea. A stomach bug? Really?

"And you are tired."

"I repeat I have stomach bug." Why didn't he get it? She had been dead on her feet for two whole weeks. She had the stomach bug, there was always one floating around. It was a hospital for goodness sakes, there was always something.

"No one else has got it."

"Look I'm taking precautions. I know that no one uses this on-call room. I make sure that I am not getting too close to anyone. I -" Her voice started to break. She didn't need this. She hadn't slept she had barely eaten, but she'd tried to be so careful about spreading it. She was saving all her sick leave so when they did get pregnant she would have enough if something came up, she would need doctor's appointments and all the other things that went with pregnancy.

"Have you been sleeping with Mark?"

"Derek how is that any of your business?" She managed to grumpily moan out

"I was absent. I gave a reason for my wife to choose him over me, but Arizona? You love Arizona, I don't understand why you would do that to her."

"Derek I am sick, I don't understand what you are talking about and quite frankly, my wife lands in four hours and forty five minutes… I have no idea what you are doing, but please let me rest my eyes before I have to go pick up my Arizona. It's the first time I will have seen her in three weeks and I would rather not look as tired as I do now."

"Arizona helped me, ok. She is my friend if you are cheating on her with Mark, if you are pregnant with his baby – that's the worst kind of betrayal."

"Pregnant?" She gasps. It finally dawns on her. The haze lifts for just a minute and she has clarity.

"Look all the signs were there… you are acting the same way Meredith did with Christopher."

She sat still for a few moments before letting out a laugh.

"I could be preg-How did I not…" Her laughter filled the room. She raises her hand to cover her embarrassed expression. She chuckles again at her complete ignorance.

"Look I like Arizona-"

"Derek not that it's any of your business but Mark is my best friend and I've never seen him happier than with Teddy. I mean he was celibate for six months for God sakes. You need to trust your friend and butt out of my business."

"But you just admitted-"

"Urgh. Derek. Modern medicine? Your ex wife? The three days a month that my wife and I have taken off every month for the last six months? Any dots joining? Before you accuse me of cheating on my wife again, think about it."

"Oh…oooooh. Uh – Sorry I- She helped me, a lot. She saved me from a bad place. I just- I wouldn't want to see her hurt."

"I get it you are looking out for her. Apparently you really are all McDreamy. But her heart is safe with me. I am the one that protects it, so…"

"I will butt out of your business."

"Thank You." She sighs exasperated. She closes her eyes.

"Torres?"

"What!" She asked, annoyed. She turns to face him for the first time since he walked into the room.

"It may be premature, but…Congratulations."

"One. Arizona is never to know that you knew before her. Two. Arizona is never to know that you knew before me."

"Get some rest Torres. How about you and your wife take the day tomorrow?"

"Thank you. And thanks for looking out for her." She meets his eyes. "However misguided it was."

He nods and she turns back around, snuggling into the pillow beside her, wishing it was Arizona. She smiled. The woman she loved was coming home for the first time in three weeks, it was their anniversary and she had some good news.

Yep they were definitely going to need a day off tomorrow.
