This is my creation of the invitro story.

It's loosely based from the storyline of the show but I changed mayor details, most will be explained by the plot. Here are some random facts
*For the invitro fertilization procedure they didn't used eggs from a donor so Taylor is Jack's biological mother
*Steffy Phoebe and Thomas all live in LA, the girls share a condo and Thomas has his own place.
*Baby Jack didn't need a surgery
*Rj was never born so Ridge and Brooke don't have a child together

Shocking news!

Taylor and Nick were over the moon. Taylor beamed all over her face. Finally their little Jack was born. He lay blissfully asleep in his mother's arms. Nick proudly looked at his offspring.

"Our son!"

"Yes, our little miracle, I can't wait to come home with our little munchkin and start our life as a family." Due to the complication during the birth, Taylor and Jack had to stay longer in the hospital than usual. But in a few days they were allowed to come home. Suddenly there was a knock, the door opened and Bridget came back to the room with a colleague and a nurse. Everyone had a concerned look.

"So are mother and child doing well?" Bridget wanted to know.

"Everything is great!" However, Taylor noticed the expressions and she got the feeling, something wasn't right. Bridget's colleague started the conversation

"Mr and Mrs Marone, we are truly sorry but it seems we have some very unfortunate news for you." Nick and Taylor looked at each other in horror. Taylor was terrified that something was wrong with Jack.

"Maybe it's better to put Jack in the nursery for a while." Taylor reluctantly handed her little one over to the nurse. As soon as she had left the room with Jack, it gushed out of Taylor.

"Now please tell me what's going on? Is Jack ill, is there something wrong with him?"

"No no no, Jack is fine, believe me Taylor he is perfectly healthy." Bridget reassured her. She signaled to her colleague that she would continue talking.

"It's not that easy to explain. At the moment we don't know exactly how this mishap could have happened. The thing is during the examinations of Jack and based on the medical data we have from both of you, I noticed something strange." Bridget took a deep breath, knowing the news she was about to share would be catastrophic. Nick and Taylor looked at her intently.

"Jack and Nick's blood types don't match. I'm terribly sorry. Nick, you're not Jack's biological father."

For Taylor and Nick this information was a slap in the face. That couldn't be true.

"No, that's impossible, I mean Nick has to be Jack's father!" Taylor didn't want to accept it. One moment ago they were so happy and now they were in the middle of a nightmare.

"Jack is my son! It can't be otherwise! The lab must have messed up and somehow switched the blood examples."

"No, Nick, it's hard for me to tell you, but it's the truth. When I saw this inconsistency, I ordered a DNA test just to be sure. Taylor is without a doubt Jack's biological mother but the paternity test was negative. I am so sorry!" The colleague now spoke again.

"The story is very unfortunate, but apparently your egg, Mrs. Marone, was fertilized with sperm from a foreign sperm donor instead of your husband's sperm. At the moment we have no explanation for this. We can only sincerely apologize to both of you."

"Apologize? You want to apologize?" Nick couldn't stand it any longer. Taylor tried to reach out for him to calm him down but all his anger bursted out.

"Apologize?! You want to apologize, you step into this room and tell us our son is not ours. With a few words you destroy our world, our family, our future and now you stand there and say you want to apologize?! I'll tell you what! I'm gonna sue you and this damm hospital. I will make sure that you and your colleagues will never ever have the chance again to ruin someone's life. Whoever is responsible for this disaster is gonna pay for this for the rest of his life." Nick was furious, he screamed, marched through the room and punched the wall. Bridget tried to comfort him but it was useless. He stormed out the room.

"I have to get out of here. This is too much. I need some fresh air! " and he was gone.

"Nick, wait! Come back!" Taylor made an attempt to stand up and follow her husband but she was too weak. She called out for him but obviously he couldn't hear her anymore. Taylor was devastated. She could only imagine how hard this news must be for Nick but it was a shock for her too and she wished he would have stayed with her so that they could support each other and deal with it together as a family. But now she was lying in this room all alone. She started to cry and to hyperventilate. Bridget was holding her and spoke softly to her until her breathing started to relax.

Bridget gave her colleague a sign, she wanted to be alone with Taylor and he left. Bridget waited until Taylor was completely calm, still holding her hand.

"Are you alright?" Taylor stared at her as if she was out of her mind. "Okay that was a stupid question. Sorry!"

"I don't know how I feel. Everything is so messed up and confusing. I still think, all this is just a really bad nightmare and when I wake up, none of this actually happened."

"I understand! This must be horrible for you and especially for Nick."

"By the way, where is he? Maybe you should go and try find him? He needs your support right now more than I.

"Alright. I will do my best. Is there anything I can do for you before I go?"

"Actually yes! Could you please tell the nurse to bring Jack back to me? I want to have him with me."

"Of course!"

The next few hours, Taylor lay in her hospital bed, somehow trying to cope with the shock. She held Jack in her arms, played and fooled around with him. Her little son finally managed to put a smile on her face.

"You know my little guy, it doesn't matter who your genitor is. Mommy and Daddy will love you very much. You don't have to be scared. Your daddy just needs some time for himself to get used to the situation. But he'll be back soon and everything will be fine." It was obvious Taylor was mostly trying to convince herself.

Later, Jack had already fallen asleep and was lying in his crib, Bridget came back to the room. Taylor was relieved to see her.

"Finally! I've been so worried. Where's Nick? How is he?"

"Well this is all very hard for him. He had a nervous breakdown, so I gave him a sedative."

"Oh my God! Where is he? Can I see him?"

"No you can't. I called Jackie and she picked him up and took him home. I think right now he's best off with her."

"Yeah sure. " Taylor was reassured on one hand, but on the other she felt a twinge. She would like to be with him right now. Bridget sat down by the bed with Taylor and smiled at Jack.

"At least the little guy seems to be doing splendidly."

"Yeah, he's so lucky he hasn't noticed any of this mess yet."

"And how are you doing?"

"I'm trying to think positive, alone for Jack's sake. We'll get through this. I'm sure Nick will just need some time and I'll be there for him. Jack is our son, no matter whose DNA he carries inside him."

Bridget looked down at the floor. Her fingers played nervously with the bedspread. Taylor noticed her behavior, but couldn't make sense of it. Bridget struggled with herself, there was one thing she hadn't told anyone yet and she wondered if now was the right time to tell Taylor. Finally, she gave in.

"Taylor, there's something you and Nick don't know, and honestly, I'm glad to talk to you alone first. Because I don't know how Nick will react when he finds out the whole truth."

"What do you mean with the whole truth?" Taylor looked at Bridget tensely.

"The paternity test revealed not only that Nick isn't Jack's father but also another detail. A link, to Jack's biological father."

"What? You know who Jack's genitor is?"

"Yes!" Bridget took a deep breath. "It's not an anonymous sperm donor and not a stranger. It's someone you and Nick know, very well indeed." Taylor looked stunned and irritated first at Jack and then Bridget.

"Now tell me! Who is it? Who is Jack's father?"
