A/N: Okay so I have abandoned my story Teach me how to Trust because basically I couldn't see it going anywhere. I have had time to think and map out a whole new story which I am much happier with. I hope you will like it!

Chapter 1 Shock

Alex looked down at his pager. ER Now That was the second time it had come through in the last five minutes. Damn it I'm on my way! Alex thought to himself. He was not the only Ped's doctor rostered on tonight.

"Dr Karev, the patient's mother over in bed 5 has refused to let anyone see her son other than you." A nurse informed him when he arrived in the ER.

"Who is the patient? Have they been admitted before?" Alex asked.

"Not that I am aware of. Patient is a 3 year old boy, Thomas Wilson, suffers from severe asthma and is settled now with some steroids and an oxygen mask. However he has had a few attacks since being here. His mother is a little frantic."

"Thanks." Alex said as he took the file off the nurse.

Alex made his way over to bed 5 and pulled the curtain around. Time stood still. He couldn't move, his head was racing with a million thoughts. She stood up, saying nothing, but her eyes told him everything.

3 years 9 months ago

"Jesus Jo are you trying to kill me?" Alex panted.

"I thought you liked it when I did that with my tongue?" Jo asked innocently whilst looking up at him from her kneeling position.

"You know I do, it's just you stop when I don't want you to stop." He said gritting his teeth.

"Oh I'm sorry I didn't realise." Again Jo said this so sweet and innocently.

Alex moved quickly and pulled Jo up and on top of him in one quick movement. It wasn't long and Alex had rolled Jo over and it was her turn to be at his mercy. Not that either of them wanted to hold out any longer. Both of them had a deep want, need and desire for each other. After Alex teased and tortured Jo just long enough he was deep inside her, the place he loved to be more than anywhere else in the world.

As both of their orgasms transported them to other times and places they felt at total peace. Something both of them were just getting used to. They had been together for almost a year and it had been just about perfect. For both of them.

The next day Alex left for work and Jo left Alex for good. She packed her things into one suitcase, and left a note two lousy words that would haunt Alex for years to come. "I'm sorry."

Alex still looked at Jo, and then his eyes turned to the little boy in the bed. No denying he belonged to Jo, he had her dark wavy hair, he had her history of asthma, he had her colouring. He just stood staring, he knew he had to move, he knew he had to treat this little boy, he was so angry with this kids mother for leaving him, loving him and then disappearing with a "I'm sorry" note. But that wasn't the kid's fault the kid needed to be treated. Yet still he couldn't stop the millions of questions that he had rolling around his head.

"Alex please...I know I have so much to explain and I...I am sorry..." Jo started.

"Forget it. Not now." He snapped.

"Hi Thomas, can you sit forward for me please?" Alex asked.

Thomas obeyed; he had been admitted to his mother's ER on so many occasions now he knew what to do. He sat forward because he knew this "Clever Doctor" as his mommy had kept telling him he was, would want to listen to his back.

"You've done this before haven't you? Good job." Alex said as he lifted Thomas's Pajamer top up and listened to the noises from his back.

Alex took Thomas's oxygen mask off and asked him some questions.

"How long have you had asthma?"

"Long time." Was the simple reply.

"He suffered croup as a baby which developed into asthma when he was two. We have tried just about everything." Jo added.

Alex nodded. He still couldn't breathe properly himself. Jo left, with no explanation no anything. She just left the day after they had spent the entire night before alternating between fucking with intense need and desire and making love with passion and gentleness. It still confused the fuck out of him. He had long since stoped torturing himself about it. It was pointless, he would never get the answers he deserved or needed to ever move on properly.

Just as Alex was about to write out a prescription for some more steroids, Thomas had another attack. He couldn't breathe and he was gasping for air. Alex's instinct for something he had never felt before kicked in. He grabbed the nearest blanket, wrapped Thomas in it and picked him up and jogged with him in his arms to the entrance of the hospital.

"What are you doing?" Jo cried chasing after them.

Alex said nothing; right now all he could do was think about getting Thomas outside, he had read a new paper on treatment of asthmatics. He had to try it.

"Alex please," Jo said as she faltered. Her panic whilst still there, was somewhat abated she trusted Alex, she always had. Wasn't that why she brought Thomas here in the first place?

Alex reached the front doors of the hospital and sat Thomas on his lap, rubbing his back, offering comforting words.

"That's it breathe in and out. Come on mate you can do it."

Within Fifteen minutes, Thomas was breathing normally again. Jo stood watching in awe, tears beginning to form in her eyes. She quickly brushed them away. This was a sight she was not prepared for. The sight of her baby boy being held by the man she loved more than she could ever admit to herself let alone out loud.

Jo approached the two people who meant the most in the world to her and sat next to them.

"Alex I don't understand."

"It's a new theory, a study has been done on one to five year olds who suffer croup and asthma, apparently if you take them into the cold air, it shocks their system. They can start breathing normally again. I thought it was worth a try."

"Thank you." Jo said quietly.

Jo was surprised; Thomas had lived a sheltered life and had only been left with hospital day care staff. He never went to other people especially if his mother was sitting next to him but Thomas was content to cuddle into Alex. He had his little head under Alex's chin, and was turned into him. Thomas has his little arm around Alex's neck, while Alex held him close and rubbed his back.

Thomas was exhausted and was quickly falling into a deep sleep wrapped in the arms of a stranger.

It was in this moment that Jo knew, she really knew, how much she had fucked up not just for herself, but for Thomas and for Alex, how wrong she had been, how unbelievably cruel she had been. It almost felt like she was intruding on a special bonding moment, watching them together.

"Alex...I have so much I need to explain to you."

"Yeah you do, but not right now, because right now I am taking our son up to the Ped's ward and admitting him for the night. You are going to get some sleep, because you look like crap and are totally exhausted. It's my turn Jo. It's my turn to be there for him."

"How...How did you know?"

"I didn't really, I've done a quick calculation of the dates but looking at his eyes, they are mine, and earlier when he smiled, it's the same lope sided smile I have. But it was more than that, I can't explain, maybe it's just an instinct. I just know that he is mine."

Jo hung her head. She was so ashamed; she had so much explaining to do. All she could hope for was that Alex would give her a chance to explain.
