AN: Hi everyone, once again this has taken me longer to get up then I thought, so I'm very sorry for the late update. I'm quite happy with this chapter so I hope you guys like it to. Thanks everyone who reviewed last time I'm very great full to you all.

Thanks to my sister for proof reading I'm very great full and thanks to deslil for a brilliant idea.

Derek POV

The trailer wasn't noise proof at all, so when I heard a car coming up the path I peered out one of the small windows. It was Meredith. She stopped the car, but it didn't look like she was going to get out. It was raining as usual so I grabbed a coat before going outside; I stopped at the end of the deck and stared at the car.

She got out and leant against the front "I've just spent two hours playing cards with your son"

I sat down on the step and looked to Meredith, slightly jealous of fact that she had spent time with him "He's great, Isn't he?"

"Yeah, he is. I spoke to your wife today; she said that she cheated" She tried to make eye contact, but I looked down at the floor to avoid it.

I wanted my chance to explain and now I had it, but I just wanted the ground to swallow me up "I came home one night, opened the front door as usual, but something didn't feel right…" I looked up from the floor to her; she didn't speak, waiting for me to go on, when I didn't she came and sat next to me "I went upstairs and checked on Leo, he was sound asleep. I carried onto mine and Addison's room, putting off the inevitable… and that's when I stepped on it… A jacket which wasn't mine." I looked to Meredith again, she gave me a supportive look "It belonged to my best friend, Mark. So I got my stuff and left." I looked to Meredith and waited for her to say something.

"How could you leave Leo?" She paused "…you can't tell me you didn't miss him, because you couldn't hide your face last night, and how you felt when you saw him again."

"I didn't plan to stay here, it just happened. I saw the chief, he offered me a job and then I met you."

She stood up, my eyes followed her. She turned back to look at me.

"Its not enough."

That's all she said. She got back in the car and was gone.

As I pulled into the car park the next day I saw Addison getting out of a taxi. I started to see red. I got out of my car and slammed the door, I focused on catching up with Addison; she was hurrying into the hospital, so I shouted after her "Addison…"

She whipped her head around, although she was supposedly only here for a case, I could see in her eyes she was happy to see me. She wouldn't be for long.

"What do you think you're playing at?"

She looked from me to the door and back again, frowning confusedly "Walking across the car park?" She paused and looked at me "What does it look like?" Her attitude was back.

"What gives you the right to tell Meredith what happened?"

"I was protecting her."

"You were what?"

"Protecting her, there was a patient. Anyway, why does it matter?"

"Because I should have been the one to tell her."

"Aww, well I'm sorry, Derek," That patronising, sarcastic tone was back in her voice "Sorry that you didn't get to milk how betrayed you were and how hurt you are just so you could get her back."

I looked at her in total dismay at what she had just said; I wasn't the bad guy that she was making me out to be "You know what, Addison? I'm done talking to you. Just go back to New York and stay out of my life."

"Would you like that, Derek? Because you know what, if I go then so does Leo." Pure evil in her eyes now; the mention of Leo just made me more angry.

"So, that's why you had Meredith babysitting?"

"What are you talking about now?" She was losing her patience with the conversation, but so was I.

"He's just a pawn to you isn't he?… You could have come to me last night and I would have looked after OUR son. But no, you can't do anything for me can you? It's all about you; It's always all about you."

"You know what, Derek? You can say and think anything you like about me, but don't you ever say I use Leo as a pawn because you're the one who walked out on parenthood these last few months, so you don't have any right."

We just stared at each other in total silence until she turned on her heel and left me standing alone in the car park.

Addison POV

As I walked away I realised he was right, I had used Leo as a bit of a pawn yesterday; I should have asked Derek, I didn't because I knew it would make Derek happy. The thing was Leo missed him so much; it wasn't fare to him, to keep him from Derek, just because I didn't want him to be happy. I didn't want to turn around but I knew I had to, not for Derek, but for Leo.

"What time do you finish work?" He began walking straight past me. He had the wrong end of the stick "Not for me," He turned around "You could have Leo, when you're done… take him for pizza, I don't know."

His face lit up. "All my surgeries are done by 3, I could pick him up after then?"

"The childminder's dropping him here at two to see Richard again. He's been bugging me ever since we last saw him."

"I bet he has." Both of us reminiscing about how close Richard and Leo were.

"You could collect Leo from Richard's room after you're done."

"Okay." He smiled, the same smile that made me fall in love with him and the same smile Leo had.

Derek POV

Meredith wasn't speaking to me, but the idea of spending some time with Leo again, just made everything better. I moved a few surgeries around so I could be at Richards's room at 2; so I could just have a few extra seconds with him. Something Addison had said to me this morning had hit me hard; when Addison did go back to New York, Leo would be leaving as well and I wasn't sure what I was going to do.

I was in Richards's room at two sharp; I thought it would take me longer to argue with Richard about clearing him for surgery and at about ten past two Addie would arrive with Leo so I wouldn't look to suspicious and then a quick 45-minute surgery.

"Stay still." I was talking to him as though he were a child; Richard kept moving as I tried to shine the light into his eyes.

"That's it-" Richard was getting frustrated.

"That's not it, stay still…"

"It is it. I can't stay still because you keep shinning that light in my face."

"I have to if you want me to discharge you and clear you for surgery." I put the light back in my pocket and then I spotted Richard's worst nightmare and I couldn't help the smile that came across my face.

"What makes you think he wants discharging?" The look on Richard's face was priceless as Adele walked into the room "Derek, don't you know this place will fall apart without him?" I smiled at Adele, just waiting for her to give Richard what for, some pay back for him calling Addison.

"Adele what are you doing here? You're supposed to be on holiday."

"You are in so much trouble, mister." She kissed him on the check "Having brain surgery and not telling me."

"It was only small procedure…" He tried to dig him self out of the giant hole he was in and it was funny to watch.

"It was still brain surgery."

"I didn't want to ruin your vacation, Adele" Adele shook her head in disbelief.

"You don't know what a vacation is, so how would you know how to ruin one?"

Richard just looked at Adele "How did you find out?" Both me and Adele were silent.

"You called my wife?" The coin had dropped, he knew it was me.

"You called mine..." Still bitter about it. "Anyway, having someone home with you is the only way I'm letting you go home."

"Fine." Richard was defeated.

Then I heard her.

"I thought I saw a fabulous looking woman walk by." I didn't turn around, but I could imagine her leaning in the doorway cup of coffee in hand.

"Addison." Adele's face had lit up and she walked over to Addison to hug her. "I told Richard that you and Addie would get back together."

"I'm here on a case" Addison corrected her and I clarified the matter.

"Addison and I are over Adele."

"It's not like we're divorced…"

"Practically divorced." Things were starting to get heated.

"You've had counselling?" Adele was concerned.

"We had adultery and that was enough." Adele began to cough, as I turned round I saw Leo standing behind Addison. In the heat of the moment I had total forgot about Leo being with Addison. By the look on Addison's face so had she.

Both me and Addie looked at Leo; I was just waiting for him to burst into tears or do something. That's when it hit me, I had no idea what Addie had said to him about me leaving, about me and her and about why they were here. Did he know about the separation? About mark? Adele broke the awkward moment as she wrapped Leo up in a hug.

"Hey, there's my favourite man."

"Hi Auntie Adele, I missed you." Leo seemed to be fine with what had just happened or he'd totally ignored it.

"I missed you more. Now, you need to tell me all about school, your friends, everything. While we let your mum and dad do their surgeries."

By the time my surgery was done the events from earlier had vanished and I was once again excited about seeing Leo. Even if I may have had to answer some awkward questions. I skidded round the corner into Richards's room; Leo was sitting on Adele's lap watching TV.

"Dad," He jumped down "Where we going then?"

"How about pizza?"

"Yay."

"Right, say goodbye to Richard and Adele"

He jumped up onto Richard's bed and hugged him and then Adele

"Bye."

"See you soon." They replied in unison.

An hour or so and most of a pizza later, me and Leo were playing flick football with a rolled up napkin.

"So Buddy, how's school?"

"It's really good, there's a new jungle gym and my new teacher is really nice as well."

"New teacher?" he looked up at me like I was being stupid

"Yes dad, I'm a year older now remember?" I smiled, feeling rather stupid now as well "She's called Mrs Michaels."

"That's a nice name." I looked into his blue eyes and was so proud to be his dad; that he was all mine.

"I finished building the model plane." Guilt crashed over me; we'd been building this plane for a while together and he'd done it without me. He was getting so big.

"You did? Aren't you getting clever."

He nodded with his cheeky smile and took a sip of his milkshake "I painted it your favourite colour."

"Really blue."

"Yeah, well mum did help a bit with the painting. She's a really good painter."

"I know, she painted the animals on your wall."

He flicked the napkin at me "Goal." He shouted at the top of his lungs, which got us some disapproving looks.

"I think you've won." I slouched back down into my seat and put my hand through my hair, Leo studied me and then copied.

"Think?…I did win." He stuck his tongue out at me

.

"Cheeky monkey…"

He looked at me with confusion, like he was trying to work out a maths equation.

"Out with it Leo, come on."

"What did you and mum mean earlier?"

I knew what he meant, but I pretended I didn't. "When?"

"When you said you were divorced?"

"Nothing, we meant nothing." I didn't know what to say. I crossed my fingers under the table hoping that 'nothing' would be a good enough answer for him.

"Liar." He sat there waiting for me to respond, he'd caught me out, it kinda made me proud at how smart he was.

"Okay, you want a man to man chat?"

"Yeah."

"Sometimes mums and dads fight," I stopped myself, I needed to be honest with him, but not too honest. "Look, even if me and mum did for some reason- I'm not saying that we are, or that we will- but if we did divorce, we'd still love you. It wouldn't change that."

"Promise?" He raised his eyebrow

"Promise."

"Pinkie promise?" He reached his arm over the table and waited expectantly.

I laughed "Pinkie… Want the last piece."

There was no answer because his mouth was already stuffed with the last bit.
