After Harry had buried the mice feeling a little upset for their death, he decided to go back home unable to stop thinking about the group of mice that had made it and where in the process of a full recovery. Blake couldn't stop talking about all the cool things he had seen while he tried to keep up knowing that he had to let Mark know. He just hoped nothing would go wrong with the mice or else he'll be in for disappointment and heartbreak all over again,

"I thought we were going home. You didn't tell me we were coming over to grandpa Mark's house." Blake narrowed his eyes at Harry, "I didn't bring my poker cards and I promised him I was going to next time I came over." He crossed his arms over his chest while they waited for the gates to open.

"You're going to stay with grandma Jay anyway, I have to talk to grandpa Mark and it's going to take me a while." Harry explained thinking that it was now or never.

"Enough time for me to convince her to bake me some chocolate chip cookies?" Blake grinned as he scratched his arm feeling a rash coming in

"If she has time and if she wants to, don't be rude about it and politely ask her if she can." Harry warned him seeing him nodding and noticing him scratching his arm, "Stop scratching it, you'll make it worse."

Blake didn't say anything and as soon as Harry had parked, he got out of the car and ran inside leaving the door open for Harry. He loudly sighed after the many times he had told him not to leave the door open and when he walked inside, he could hear him loudly chattering in the kitchen where he assumed Mark and Jay were.

"...and then I got to see a heart beating outside the body! Isn't that cool, grandpa?" Blake said as he stuffed his face with watermelon and Mark smiled and nodded along wondering why Harry had been in the research center.

"That's amazing, champ!" Mark genuinely told him making Blake grin.

"Harry!" Jay exclaimed, "Would you like some watermelon, love?" She asked him.

"I would love to." Harry smiled taking a seat next to Blake then started eating from the plate Jay placed in front of him, "Mark, I need to talk to you...when you're done eating of course." Harry said seeing him nodding.

When they were done they made their way to Mark's study having left Blake back in the kitchen with Jay after the little boy had convinced his grandmother to bake him chocolate chip cookies, with his help of course. As soon as Harry had closed the door he turned around to see Mark looking nervous just like he was. He didn't know how to even start the conversation since it was already hard on him.

"I was informed today that Group A dropped dead..." Harry started getting interrupted by Mark.

"Again? God..." He rubbed his hands on his face pacing back and forth in front of his desk.

"But Group B, the one we used the tissue-specific stem cells on...they're recovering. You told me you froze healthy stem cells from Louis' heart before freezing him, and if the MHRA approves it and the clinical trials then maybe there's hope." Harry explained seeing Mark carefully listening to him before his eyes filled with tears and a smile slowly appeared on his face.

"Harry...son, you did it. You did and...you hate me and you probably don't care but I'm so proud of you. Not because there's a chance to bring Louis back, but because you've succeeded in everything you've set out to do." Mark genuinely said making Harry get a little emotional when the praise had come from a father figure.

"I honestly thought I would never find something, and I gave up but now I don't know what to do. I keep thinking that this is it, that we can bring him back, but I also can't stop thinking about the consequences. Mentally, emotionally and physically."

"There's many factors." Mark agreed, "He's been there for nine years so we don't know the state he'll be in if he ever wakes up."

"I don't want to bring him back and have him hate us for what we did to him, I don't want him to suffer at all." Harry confessed keeping the tears at bay seeing Mark doing the same even though he tried to fight it and hide it.

"You have the last word, son. You decide if you want to unfreeze him and let him rest in peace or unfreeze him and try reanimating him. What I think doesn't matter anymore and I understand that now even if it's too late, it's you and Blake who matter and I'm not gonna go against whatever you decide." Mark placed his hand on Harry's shoulder squeezing a bit for comfort before he let go.

Harry took a deep breath taking a seat on one of the chairs with his hands on his face not knowing what to do at all. He wanted him back with them, he wanted Blake to finally meet and have his father around. He wanted to finally get his happily ever after with Louis, he wanted to be happy with him and have that family he's always wanted. The family they've always wanted ever since they had told their first I love you's to each other.

He still remembered the many times they had imagined the big family and house they were going to have. Louis had taken a liking to cooking thus wanting a big kitchen equipped with everything, something Harry had made sure it came with the home he bought. The many more kids they were going to have a few years later after Blake's birth and what they were going to name them. How they wanted a little girl to spoil her extra and how their baby boy was going to be the best big brother ever.

He wanted all of that, but the thought of Louis facing many obstacles after reanimation was enough to keep him from doing so. He didn't want him to suffer at all but the need to have him back in his arms overpowered his own morals. So taking a deep breath and pushing those thoughts out of his mind, he looked up at Mark and made his decision.

"We should wait for the MHRA to approve it and if they do we start clinical trials as soon as possible then we...we unfreeze and try reanimating him if all goes well. But just once, if it doesn't work then it doesn't." Harry decided and seconds later, Mark nodded hoping for the best.

"When are you going to call them?" He asked.

"We'll wait a few days to see if the mice keep improving while I gather enough data then I'll have them get involved. I just hope they approve it, this is our last hope." Harry got up from his spot barely hearing Blake's laughs, "And if Louis ever wakes up...hopefully he'll understand, hopefully he'll accept Blake even though he no longer is the baby he left behind." He expressed his sudden worries then started chewing on his bottom lip.

"Blake is his son, Harry. He loved him with everything he had and I'm sure he won't stop loving him now just because he's older." Mark said taking a seat on his desk looking at a picture of Louis when he had turned seventeen years old.

"I'm not sure how he'll react to the rest of us but as long as he accepts Blake then I can't complain." Harry gave him a small lopsided smile seeing Mark smiling a little.

Harry ended up leaving a few hours later wanting Blake to spend time with his grandparents, and when they got home he was already full after Jay had asked them to stay for dinner. The next few days for Harry seemed to pass by slowly with the fear of the mice dying or the organ regeneration completely stopping.

He had gone to see Louis again unable to help himself when he told him all about the mice, almost as if Louis could hear him yet he knew that wasn't the case. He had yet to let the rest of his friends know about it not wanting to bring their hopes up in case it didn't work. Something that had become his biggest nightmare having replaced his old ones.

To his relief, the mice only seemed to keep getting better and just like that he was in front of a miracle. It was as if they had never been born with a diseased heart when they were now completely healthy. He was still mourning the other many dead ones he had had to use before but it had been necessary.

After getting the MHRA involved, days turned to weeks that to Harry were going by painfully slow when they were taking forever to conduct their own researches and tests so he could start his own. By September Harry was sure he was going to go insane when his son had gone back to insisting that he wanted to see Louis only to get the same answer from Harry leading to arguments then the silent treatment.

~*~

"Blake, open the door or I swear I'll take it off. I don't care if you need your privacy, you don't deserve it if you're gonna act like a brat!" Harry yelled at his son as he repeatedly knocked on the door, each knock stronger than the one before.

"Go. Away." Blake growled from the inside grabbing his teddy bear and throwing it at the door, "Louis left us, didn't he? And you're a liar just like him!"

"I'm not going to tell you again, Alexander! Don't make me go get the keys." Harry shouted trying not to lose his patience but the longer it took Blake to open the door, the more his patience was wearing thin.

"No! Jeffrey was right and he left us, he's an asshole!" Blake let out a loud sob not knowing what to believe, he knew they were keeping something from him yet couldn't figure out what it was no matter how hard he tried.

What was so wrong about seeing him now just like they did if it was true that he was frozen in his grandfather's institution. He stopped crying when he could no longer hear his father outside the door and that's when he started panicking. He ran to his closet when he heard Harry's footsteps and seconds later the doorknob jiggling before the door opened and a furious Harry walked in. He looked around then got on his knees to look under the bed then his gaze settled on the closed door of the closet quickly getting up to open it.

"I didn't mean it!" Blake cried as soon as his father had opened the door expecting a punishment but instead of his father yelling at him, he only felt his arms around his small body holding him tight against his much larger one.

"I don't care how upset you are, but don't you dare call your father something as awful as you just called him. Do you understand?" Harry pulled him away a little seeing how red his face and eyes were from all the crying then hugged him again rubbing his back.

"I'm sorry!" Blake sobbed against his chest, "I want him..." He continued crying completely breaking Harry's heart.

"I'm trying, Blake." Harry said against the side of his son's head, "I'm really trying but you have to understand that things don't always turn out the way we want them to. As sad as it sounds, we don't always get our happy ending...our lives aren't like the fairytales Nana Anne reads to David, Michelle and you." He tried to explain as best as he could in a way so he would be ready to let him go if things didn't go as planned.

"But you p- promised, papa. You told me h- he was coming back." Blake pulled away to look at him with teary blue eyes.

"I know I did, baby. I know and I'm sorry, I'm sorry I kept promising you he's coming back when even I don't know if he is, I'm trying so hard to make it possible. You need to understand that." Harry finally gathered enough courage to tell him once and for all.

"But you're so smart, papa. You can do anything you want when you use your brain." Blake said so sure of himself, "You even had me listen to Mozart when I was a baby because his symphonies make you smarter."

"That was debunked, bud." Harry chuckled, "It makes you take a liking to his classical music but it won't make you smarter." Harry hugged him closer.

"I like them...kids in my class think I'm weird and sometimes make fun of me because I said I like his music." Blake confessed.

"Ignore them, every single one of us have our own taste in music and what others think shouldn't matter to you. If it makes you happy then there's nothing wrong with you enjoying a little bit of Mozart or any other kind of music you would like." Harry kissed the top of his head running his fingers through his soft hair, "If they keep doing it let me know and I'll talk to the teacher and their parents."

"I got it, papa." Blake's eyes widened not wanting his father to get involved. That would be embarrassing for him.

"Okay then. How about we go and have dinner?" Harry asked getting up as he wiped away his son's tears.

"Race ya!" Blake got up as fast as he could then ran out his bedroom while Harry smiled and let him win now that he was a little happy even though he knew it wouldn't last.

Soon he would start asking again, it happened every single time no matter what.

A week later he was on his way back home sometimes glancing at the passenger's seat where a box sat wondering if he was even doing the right thing. As soon as he got home, his mum's car was already gone since she had a doctor's appointment and Blake was okay staying ten minutes alone.

When he parked and turned the engine off he made sure the garage door had closed then grabbed the box and made his way inside where he could hear the tv. He walked into the game room where Blake was sprawled on the couch eating Reese's pieces and watching Regular Show sometimes laughing when something funny happened.

"I'm home." Harry said placing the box on the floor where he was still standing by the door.

"I thought you were never going to come home. I was about to call the cops and an ambulance." Blake said never taking his eyes off of the tv, "I thought I had become an orphan."

"Don't be so dramatic." Harry chuckled remembering when Louis used to do the same thing.

He just hoped he could do it again one day.

"What's in the box?" Blake asked finally acknowledging his father.

"It's a present for you." Harry answered seeing the confusion written all over his face.

"But it's not my birthday." Blake got up from his spot getting even more confused but when he heard the small yaps coming from inside the box, he gave Harry a thousand watt smile kneeling down next to it.

"He's a boy." Harry crouched down next to them loving the way his son was smiling.

"You got me a puppy!" Blake's eyes started watering as he hugged the Golden Retriever close to him then hugged Harry making sure not to squeeze his new friend.

"And you get to name him, all by yourself." Harry wrapped his arms around him rubbing his back.

"He looks like," Blake paused to look at the playful little ball of fur giggling when he started licking his chin and wagging his tail, "Harley! Uncle Niall has a Harley and he always gives me rides!" He exclaimed then smacked his hand against his mouth widening his eyes.

"Oh thanks for telling me, bud!" Harry chuckled not even minding that Niall hadn't listened to him when he told him not to let Blake ride it with him when his son was so happy, "Next time he lets you ride with him just be very careful, okay."

"I will, papa. Thanks for getting Harley for me, it was the best present ever!" Blake hugged him again then let go to hug Harley and kiss the top of his head, "I love you." He told him feeling happier than ever knowing that now he had a friend and wasn't going to feel alone waiting for his father to get home from work.

"You are very welcome, son." Harry smiled at him, "How about we go and get everything he's going to need?"

"Yes! Let me put my shoes on." Blake quickly got up leaving Harley on the floor next to Harry.

The puppy was quick to follow Blake everywhere he went and soon they were out the door and into the car where Blake had the puppy on his lap holding him tight against his chest. When they got to the pet store Harry grabbed a cart letting Blake hold Harley always showing him all the toys and collars so he could pick the ones he liked. As soon as they were finished Blake was excitedly showing Harley all the things they had gotten for him.

They got home a few minutes later where Harry had to carry all the bags inside when Blake was too busy playing with Harley. When he was done he started dinner smiling every time he would hear his son laughing noticing that he hadn't asked about Louis once. He was still waiting for that call and couldn't help but start to get desperate fearing that they weren't going to approve the treatment much less let him start clinical trials. They finally sat down to eat leaving Harley to walk around the kitchen always staying on Blake's side of the table.

Another week passed by and Harry only kept getting more desperate knowing they were wasting time and that was something he couldn't deal with anymore. He had waited nine, almost ten years now for that moment where he would get to hear Louis' heartbeat again and feel his warm smooth skin against his fingertips. He would get another chance to see his blue eyes again and run his fingers through his silky hair like he used to do, it helped Louis relax and fall asleep.

He had to admit he was scared of what Louis' reaction would be to everybody and everything. He was scared that upon Louis seeing him, he wasn't going to like what he saw, that he will fall out of love with him. It was one of Harry's worse nightmares frightening him to the point of leaving him shaking and trying to catch his breath feeling his heart about to beat out of his chest. He was afraid of Louis leaving him to be with someone his own age even though he was legally twenty seven but his body and appearance was that of an eighteen year old.

But there were many more, more where he would reject their son and to him it will hurt more than Louis rejecting him and no longer wanting to be with him anymore. There were a million but the worst of them all was the reanimation itself not working when they only had one chance to do it. He tried to think positively but it kept getting harder not knowing what to expect after Louis had been frozen for so long. He was well preserved but there were many factors they had to take into consideration. Things that he didn't like to think about.

That wednesday morning in the middle of september he found himself laying down on the couch in his office trying to take a much needed nap. He closed his eyes but seconds later opened them again staring at the white ceiling unable to stop looking at it. He sighed rather loudly then got up to review his patients medical history to be more informed than he already was when the phone started ringing. He answered without even looking at the caller ID saying his last name almost automatically.

"Dr. Styles, this is Dr. Hudson." A gravelly voice was heard through the phone making Harry sit up straight.

"Dr. Hudson, it's an honor to hear from you." Harry said knowing that was it, the man on the phone held his and his son's future in his hands. But most important of all, he held Louis'.

"It is an honor to be speaking with the Harry Styles, your research in organ regeneration has left me speechless. You are just what we need in the medical field. I've never had the pleasure to hear about someone like you, such a genius." Dr. Hudson said then continued not letting Harry talk, "We've decided to give you and your team the go ahead to start clinical trials. We wish you the best, Dr. Styles."

"Thank you!" Harry said unable to stop smiling then said his goodbyes before hanging up. He stayed there for a few minutes then got up to let Mark know.

As soon as he had let Mark know, clinical trials started as soon as possible taking almost all of Harry's time. He knew it was wrong to not spend as much time as he used to with Blake but he needed to gather as much information as he could. He needed to hurry up and help Louis. He wanted to give him another chance. He wanted Louis back with them, he wanted the family he could never give Blake.

When the selected patients started getting better without needing a heart transplant since ther own heart had slowly regenerated, Harry had announced that they were ready to try it on Louis. Sure, there had been side effects such as aggressive nausea and vomiting but he had found the medication to alleviate it to a comfortable enough symptom without affecting the organ regeneration. That was the day Harry was seen as their savior by many whose heart was too damaged and in need of a transplant. He was what those in need needed and had waited for too long.

Even though Harry was more than ready, he couldn't help but feel nervous afraid of something going wrong. He was afraid of reanimation failing or something going wrong after it. He had avoided telling their family members and friends about finally unfreezing Louis not wanting to give them false hope. He couldn't get their hopes up for nothing. He hated to have Jay still believing they were finally going to have a funeral, he hoped it wouldn't be necessary.

When the time finally came he found himself in his office in Tomlinson's Cryogenic Institute unable to even move an inch when soon enough, Louis will be among the living once again. He wasn't able to see him when they were getting him ready to unfreeze him yet didn't worry much when Mark was in charge. Louis was completely safe with him and Harry didn't have the courage to see him while they were doing it. He was going over Louis' file one more time already having memorized it after all those years obsessing over it when he heard a knock on his door then someone opening it.

"Dr. Styles, they're ready for you." Dr. Silverman said showing no emotions at all making Harry feel afraid of the unknown, "They were waiting for him to completely thaw before starting the blood transfusion." She informed him seeing the way he flinched at the term.

"He's not a piece of meat." Harry glared at her making her look down at the floor in shame, "He's my son's father...my...my..." He trailed off.

The sudden realization of not knowing what he and Louis were anymore hit him with enough force to make him breathless.

"The love of your life, your soulmate. The person you fell in love with and worked so hard to try and bring back." Dr. Silverman said seeing Harry's pained expression still thinking about the word she had used, "I'm sorry Harry, but those are the terms we use no matter how unpleasant they are. Won't happen again."

"I- I overreacted, I'm sorry." Harry rubbed his hands on his face then made his way towards the door, "We should go, I still need to get ready and we don't have much time. I should have been there through the entire process, I just- I didn't have enough courage for it."

"I understand." Dr. Silverman said as she fell into step with him.

They walked the rest of the way without saying anything until Harry found himself getting ready and when he was done, he walked into the operating room clad in surgical scrubs, shoe covers, cap and mask. He stopped when he saw him on the operating table completely bare with only a drape sheet covering his lower half seeing his hair was wet and his skin didn't look as pale as it had been for the past nine years.

What caught his attention managing to steal it away from Louis was the blood bag hanging from the IV pole among the others at a table waiting to be used. He then followed the cannula until his gaze settled on his chest where it was inserted into a vein in his chest pumping blood in as fast as it could not wanting to waste any time. He wanted to get closer and be able to touch him but couldn't when his feet wouldn't move recognizing Mark as the surgeon running his glove clad fingers through Louis' wet hair.

The room was a bit chilly to him but soon warmed up a little at just the ideal temperature to keep them and Louis comfortable. As soon as Louis' heart was beating again, he would need to be warmed up as quickly as possible to prevent hypothermia.

"It's almost done. Once they give us the go ahead you can start reanimation." Dr. Silverman informed him giving Harry a little push sighing in relief when Harry finally reacted and made his way there.

"You'll be okay, son. And when you wake up, I hope you can forgive me."

Harry heard Mark whisper when he was close enough to them feeling somehow sorry for him but not enough to be able to fully forgive him himself. He finally willed himself to look at Louis and when he did, he felt the air leaving his lungs seeing how beautiful he truly was, the way his eyelashes fanned over his pale skin that was starting to turn a bit purple.

Dark circles under his eyes, Harry had expected them knowing very well that Louis wasn't healthy at the moment. It felt like forever where all Harry did was stare at Louis while they were filling him up with blood until there was a small amount left in the last bag of blood. He felt cold when as soon as they connected him to the heart monitor, all they heard was the long beep signaling there was no heartbeat.

"He's ready for treatment then reanimation." A doctor informed them making Harry and Mark look at each other.

That was it. That was what they had been waiting to finally be able to do for the past nine years, and now that it was happening they only had a one chance to bring him back.

"Dr. Styles," Dr. Schooley said, "When you're ready."

Harry nodded at the same time he took a deep breath quickly getting to work and while he injected the stem cells into Louis' bloodstream through the IV, he couldn't help but look at the C-section scar on his lower stomach. It still looked red and he hated the fact that it was one more thing Louis was going to have to heal if he even made it. Once he was done, he handed the utensil back to a nurse then stepped back a little taking the paddles already ready for him.

"Stand clear." Harry said loud and clear seeing them moving away as he brought the paddles closer to Louis.

He felt the pain, even if it was only in his mind, he felt it when Louis' body slightly shook with the shocks that did nothing to get his heart beating again. He tried again quickly looking up at the monitor when he heard the small beep sound only to flatline again as he got ready to try again.

He couldn't and wouldn't give up. Not again.

"C'mon, Lou. Please..." He whispered as he put effort into it when he tried one more time, "Please, come back." He continued whispering, kept repeating it almost like a prayer until they were answered.

His eyes filled with tears when they heard the constant beeps telling them Louis' heart was beating again then Mark was quick to place an oxygen mask on him to get more oxygen into him. Harry sighed in relief looking at the monitor then back at Louis unable to believe he was actually breathing again and his heart was beating once again after so many years.

Nurses quickly placed electrical blankets over him to try and warm him up while Harry handed the paddles over to a male nurse. He shared a look with Mark before taking a step closer to Louis and just when he was about to touch him, to caress his soft cheek, he heard it making the room fill with that haunting sound and the many voices of the medical staff. He didn't caught up on what was going on when the only thing he could do was look at Louis until he did breaking his heart all over again.

Louis had flatlined once again and this time, there was no going back and nothing they could do.

Have some faith on me and don't come after me!!
