Mark found Addison walking out the day care. He had been looking all over for her and funnily enough, didn't think to look in the one place that was most obvious, other than the OR. Before Mark could say anything, Addison said, "I suppose you want to talk now, right?"

Mark sighed. "Yeah. Look, I'm sorry about before, it's been a crazy couple of days."

"Well I can't right now, I need to go and deliver a baby to a mother who is less likely to survive the birth and then a set of twins straight after that where one of them is breech, not to mention that Cammie won't settle so I need to keep running back and forth so now is really not a good time, Mark!" Addison snapped.

Mark was a little take aback. Addison had never spoken to him like that. "I'm sorry I didn't know. I'll leave you to it."

She grabbed his arm as he turned to leave. "Mark wait. I'm sorry, I didn't mean to snap."

"It's okay, forget about it."

"No it's not okay. I'm under a lot of stress at the moment and I just can't handle it anymore." She said, trying hard to swallow the lump that had quickly formed in her throat.

Mark looked at her sympathetically. "Hey, come on, this isn't like you. You don't crack under pressure and you certainly don't cry."

"A lot has changed in five years Mark. I do crack under pressure and I do cry – a lot actually. And you know what? I'm fed up of it." Just as she finished speaking her pager went off saying she was needed in the day care right after she got a 911 from a mother and baby going in to distress. Addison groaned and tried to fight back the tears that had made their way down her cheeks. "I can't do this, I just can't do it!"

Mark pulled her in to an embrace in an attempt to comfort her and sighed. "Go and answer the 911 and I'll go and see Cammie."

"But she needs me, she needs her mom."

"Addie, she also needs her dad. Go answer the 911."

This was the time that she was most grateful for Mark. She didn't know why she was so worried about telling him about Cammie in the first place. She should have known that despite everything, he would always be there for her. Addison pulled away and smiled weakly at him. "Thanks Mark."

He smiled back at her and kissed her forehead. "It's no problem. Look, we do have stuff to talk about. Meet me tomorrow morning and I promise, I won't leave you."

"Yeah, sure." Addison smiled weakly.

"Now go and save your patient." He chuckled to himself as it hit Addison's face that she probably needed to be in the OR and quickly ran off to the patient. He started to make his way over to the day care when it hit him what he had promised Addison he would check on his daughter in the one place that he knew he couldn't. He had no idea how he was going to get away with this one.

Zoey made her way down the Day Care after she had spoken to Derek. As she walked in, Mrs. Smyth was tending to a little girl was in floods of tears. "Zoey can you please take over?" she heard her call to her. She nodded in response but soon regretted it when she saw the small redheaded little girl clearly in distress. She hesitated and considered making an excuse like running off to the toilet or even complaining of a cold, anything to not have to comfort that child – the spawn of Satan. "Zoey, can you come over here? I would continue but I can't get hold of her mother so I'm going to have to try a few calls."

Zoey sighed. "Sure." She knew none of this was her fault so she shouldn't blame her. Plus, she was extremely unhappy and unsettled about something. Perhaps Cammie knew she had taken an instant disliking to her. She walked over to where Mrs. Smyth had left her and sat down on one of the empty chairs, pulling her on to her lap and let her lean in to her chest. Fifteen minutes had passed and Cammie had finally calmed down and fell had fallen asleep in the corner. She wondered where Addison had got to and why she had left her daughter alone with strangers when she was in that state. She got up and went to get some paperwork for one of the mothers when Mark walked in. She turned round the corner, away from Mark's view, so he couldn't see her as she wanted to see why he was down there. "Can I help you?" she heard someone say to him; Mrs. Smyth had just come back in.

"Yeah, I'm looking for a child."

"This isn't an apartment store. Who are you looking for?"

Mark sighed. "Yeah, sorry. I'm looking for Cammie Montgomery." He said.

"Who are you in relation to her?"

Mark hesitated. "She's my friends daughter."

"Do you have written permission from the mother to see her?"

"Well … no. But she did ask me to check on her to see if she's okay."

"Sorry sir but unless you have written permission from the mother then I can't allow you to see her."

"Okay, I'll level with you, I'm her … um … I'm her father." He said quietly, clearing his throat and looking around, mainly to make sure no one had heard him say that. Thankfully, no' one else did; or so he thought.

"You're her father?"

Mark nodded. "I am."

"I'm going to need to speak to her mother first, just to make sure. Don't take it personally, I'm sure you are her father; I just need to double check. You could be anyone and I have a responsibility for the well fair of all children in my care."

"Okay but can you just tell me how she is then? Just so I can tell her mom."

"She's finally settled down but she was in quite a state. If you see her mother, can you tell her to talk to me about it."

"Okay, will do. Where is she now?." Mark asked.

"She's asleep in the corner but I can't let you go over there."

"I understand." He replied, looking over to the sleeping bundle. She looked so peaceful, what had got her so agitated that would put her in such a state. What would he have done if he had witnessed it? Would he be able to comfort her? He very much doubted it. "Okay, thanks." he called over to Mrs Smyth who had gone off to try to get hold of Addison. He took anther glance over at Cammie before turning to walk out. At this point Zoey thought it would be a good idea to make her appearance known. "Hey!" she called out to Mark, making his heart race due to fear of her finding out the truth about Cammie and the fright of her popping out of the blue. Zoey ran over to him and placing her hands on his shoulders, she reached up and kissed him on the lips gently. "What are you doing here?" she asked him casually.

"What? I was – I was looking for you." Mark replied nervously.

"Oh really? Well I've been in the room all day, haven't left."

"What?" Mark started to panic. Could she have overheard his conversation with the other lady? Could she know that the red headed little girl was his? Even if she didn't hear, it was possible that she put Cammie's age together with the time he had slept with Addison and worked the truth out on her own.

Zoey could hear the panic in his voice and she could see it in his face and yet she refused to tell him that she knew all along. It was way too early and she wanted the timing to be perfect. "Yeah but it doesn't matter. I'm glad you're here; there's something I need to talk to you about. Something really important."

Mark prepared himself for the worst. Things with Zoey wasn't going too badly apart from the Lexie thing. He knew that whatever was coming next would eventually be the end of their upcoming relationship. "Oh. What's that then?" Mark winced, as he waited for the slap that would soon go across his face.

Zoey's face broke in to a grin. "Relax will you. It's your birthday next week and I heard that you didn't want to do anything for it. What's up with that?"

Mark let out the breath that he had held in and a laugh escaped, mainly out of pure relief. "Oh Zoey, I wish you had started with that. I thought you were going to say you knew about-" Mark stopped abruptly. Was he seriously going to let his secret slip?

Zoey narrowed her eyes. "You thought I knew about what?"

"You knew that, erm, that Addison's in Seattle."

"What?" Zoey said, pretending to be shocked and succeeded. "When did she get here? Who is she?"

"She's the new attending. She's been here for about a week now."

"And you didn't think it would be a good idea to tell me? You know how much I despise that woman, Mark!"

"Exactly! What would be the point in telling you? All that would happen is you would get wound up and start something in the hospital. There would be no point. Besides, you're not exactly going to bump in to her are you?"

Ha! Zoey thought to herself. Too bad I already have and do – every single day! "Yeah. Not unless she has a child in day-care." She said, putting extra emphasis on the words day-care. "Oh hang on a moment. Her last name wouldn't be Montgomery, would it?"

"Ye-es." Mark replied slowly.

"You know what's funny?" Zoey laughed shortly. "I have met her already. I see her ever day when she drops her kid off in the morning when she starts her shift."

Marks heart sank. He had no idea where Zoey was going with this but he didn't like it. He just prayed she didn't know he was the father. How would she know? Unless Addison told her but she had no reason to tell a day-care worker who her father was. Unless Derek …

"Mark did you hear what I said?" Zoey asked, raising her voice slightly, bringing his attention back to her.

"What?"

"Did you know she had a child?"

"What? No! How would I know? I haven't seen her for five years!"

This time it was Zoey's heart that sank. She had no attention of letting on that she knew the child existed but seeing as that was where the conversation led to … she couldn't believe she actually thought that now Mark knew she knew Addison had a child, he might admit to actually being her father. "You had absolutely no idea that that five year old girl sleeping in the corner, belonged to Addison Montgomery? The woman you slept with five years ago."

Mark knew that he should probably tell the truth but he was too scared of losing Zoey. So he did the one thing he was best at – he lied. "No Zoey. I didn't have a clue that she belonged to Addison."

"You had no idea she was pregnant?"

Mark shook his head. This time, it wasn't a lie. He really had no idea that she was expecting a child when he took off to find Derek.

Zoey was slowly starting to despair. So she asked the one question she knew she needed to ask. "You are definitely not that child's father then?" A nice and simple yes or no answer – no loopholes.

Mark swallowed. "No, Zoey. That's not my child." He said hesitantly. Zoey nodded but she could feel her eyes start to water. There was no way she could let him see how badly his lies were affecting her. So she did the one thing she was good at. "I have to – have to go." She mumbled and legged it out the room, leaving behind a confused and guilt ridden Mark.
