Hey Nuggies! So here's the rewrite to 'What Could Have Been' and I can tell you know that this rewrite is going to be a little different that the original as I decided to do some things and not to do other things. It will still be SLASH and M!PREG along with the other warnings in the original that I'll post right under this little note for everyone to see. Anyways I hope that you all enjoy reading this and don't forget to fav, follow, and review!

Rating: M

Fic Warning: Slash, M!Preg, genderfluid, crossdressing, and other warnings I'll add once I think of them.

Chapter Warning: None

Disclaimer: I do not own Harry Potter.

AN: Even though J.K.R. had it in her books that the populace found out the 'death' of the Dark Lord and Lily and James Potter the very next day (or that night even) in this they did not find out until later. The deaths of Lily and James Potter had not been found out by anyone, but the person that murdered them. Everything about this will be explain later in the fanfiction. (This is here to help people make sense of the ending of this chapter)

Hadrian clung tightly to Sev as he felt like he was being forced through something tight by his tummy. When the feeling stopped he cautiously opened his eyes and saw the biggest house he had ever seen. It had towers and a large lawn with large white birds walking around; he had even seen one with its tail flared wide as Sev walked up the walk way to the front door. "Sev? Where?" He asked softly as he large doors opened silently to reveal a large entry room. He could see their reflection on the floor as Sev swept his way to the left side of the staircase.

"We're at my home, sweetness," he said softly as he rubbed his back. He was surprised that the young child wasn't sick after apparating as most were with side long appariations. He felt Hadrian nod against his shoulder as he made his way to where he could feel his husbands magic. He stopped in front of the open door and peered in with a small smile at what he saw. His husband, Lucius, had their son in his lap and was quietly reading to him. "Husband mine," Severus said as he entered the room.

Lucius looked up and saw his lover walk in with a small, smaller than their own son, child on his hip. He took in the features of the child as he opened his mouth to answer his lover, "Yes love? Who do we have here?" he asked softly as he set Draco, their child, down on the couch beside him before standing up and walking towards Severus.

"His name is Hadrian," Severus said quietly as he glanced down at the curious child. "Would you like to get down?" he asked the child as he gestured to the toys several feet in front of the fireplace. When he got a small nod, he set him down on his feet and watched Hadrian sit down beside the toys and grab one of the big blocks.

"Love?" Lucius said softly as he reached up and placed a hand on Severus' arm to get his attention again, "Where did he come from?"

"Oh Lucius, I found him sitting on the cold concrete crying his heart out. He was sitting in my old neighborhood. You know it's abandoned now that I have moved here," Severus said softly so Hadrian and Draco, who joined Hadrian, couldn't hear him, "I couldn't leave him. He has magic in him. For all we know his muggle parents abandoned him there to rot and waste away." He felt arms wrap around him as he shook in anger.

"It's alright love. I'm glad you brought him here if he was truly abandoned like that," he said to Severus as he rubbed his back, "We can go to Gringotts and ask for a blood test to be done, will that be alright with you?" He smiled as he felt Severus nod against his chest, "Now it's about lunch time, why don't you get young Hadrian ready while I take Draco to the kitchen?"

"I can do that," Severus said as he pulled away not before kissing his love on his cheek. He walked over and knelt and spoke to Hadrian softly before picking him up. He kissed his sons head softly before standing up and placing Hadrian back on his hip and carried him out of the room. He was going to give Hadrian a bath and put him in some of Draco's clothes. Merlin knows his baby boy has more than enough.

Hadrian looked around at all of the paintings and watched curiously as they moved and spoke. There were a few that even greeted him! They passed statues and vases and many other decoration items he didn't know the name of until they stopped in front of a regular looking door. When Severus opened it Hadrian's eyes widened as he saw the colorful room. He saw so many toys! "Sev! Play?" He asked excitedly as he kicked his legs wanting down so he could play with everything.

"Not yet Hadrian," Severus said as he got a tighter hold on the child, "You can play with them tomorrow. Right now it's bath time then lunch time." Hadrian pouted as he figured out he wasn't being put down. He felt the tighter hold and stilled from his kicking so Severus could relax his hold.

"'K," was all Hadrian said as they walked past all of the toys to a door Hadrian didn't see earlier. When they walked into the room he saw that it was a normal room like the one he had at home. There was a crib, a changing table, a smaller box of toys, and two more doors. He was set down and was told to stay where he was as Sev walked to one of the door and opened it.

Severus rummaged around the small wardrobe they had in the small walk in closet in their sons' room. On the opposite side of the wardrobe were clothes hanging by hangers and aligned shoes on the bottom. He grabbed a green long sleeve onesie from one drawer and a pair of dark blue jean overalls from the hanger. He also remembered to grab a pair of warm socks and one of Draco's extra never worn pair of sneakers. With everything gathered he returned to the main room and saw Hadrian right where he left him. "Alright sweetness, are you ready for a bath?" he asked softly as he led the toddler to the other door in the room to reveal a bathroom.

Hadrian toddled in and looked around at the bright room. He saw some toys and didn't know why they were in here since toys didn't go in the bath. He watched as Severus set the clothes down on the counter and then moved to what looked to be an even smaller closet that only revealed to hold towel and smaller cloths. The next thing he watched Sev do was turn on the bath and pour something in the water that he could smell was slightly sweet like strawberries. He watched amazed as the water began to bubble up like when he blew through the straw in his milk. He looked up at Sev and pointed at the bath, "Bubbles!" he said happily as he bounced on his feet.

"You like the bubbles?" Severus asked amused and got a happy answer of a loud yes. He chuckled as he turned Hadrian to himself and started taking the dirty clothes off of him. He took the dirty diaper and threw it in the trash by the potty training toilet and then picked Hadrian up. He tickled the little boy to make him giggle before setting him down in the shallow bath. The warm water only came up to his belly button, but he made sure to keep a hold on him.

After the bath was done and Hadrian was dry and dressed Severus picked him up and carried him out of the room. He made his way down the stairs and into the kitchen where he saw Lucius stirring a pot and Draco sitting in his toddler chair at the table and coloring. He set Hadrian at the table with a conjured toddler chair and gave him a few crayons and paper before walking over to Lucius to see what he was making. "I see we're having macaroni and cheese," he said with a small smile.

"We also have those small pieces of breaded chicken in the oven," Lucius said as he turned the stove off and pulled the now cooked noodles off the burner. Lucius, at Severus' insistence, had taken a few muggle cooking classes and it seemed like the older blond had a knack for cooking.

"Ah yes, Draco's favorite," he said as he remembered Draco's face when he first had chicken nuggets, "Did you remember to make a vegetable for us?"

"I have not done that yet. I didn't know which one to make," Lucius said as he drained the noodles then added the rest of the ingredients to finish it off. "I was going to make green beans, but I didn't know if our little guest liked them," he explained as he saw Severus' raised eyebrow out of the corner of his eye.

"I see, I think the green beans would have been fine," he said as he went to get the said vegetable. Hadrian looked up from his drawing and carefully got out of the chair with the picture in his hand. He walked up to Severus and tugged on the man's pants. Severus looked down and saw him before kneeling, "What is it sweetness?"

"I drewded a picture for you," He said as he handed the picture to Severus, "There's you, and D'aco, and Luc'us," he pointed to each blob with different colored hair, "and me," he said as he pointed at a smaller blob beside the bigger black haired blob.

"Thank you, sweetie," Severus said as he held the picture, "I'm going to put it on the fridge, okay?" He stood up one he go a nod and placed it on the fridge with one of the magnets he managed to convince Lucius to get. Hadrian smiled widely as he turned and walked back to get in his chair to draw another picture. A few minutes later Severus was telling the boys to clear off the table so they could eat. It only took a few minutes for everyone to eat the simple meal and to clean up. Severus told Draco to take Hadrian to his playroom for a little while to play before taking a nap as Lucius and himself took the time to relax.

It was a few hours later when they were all ready to go to Diagon Alley. Severus held onto Hadrian as Lucius took Draco through the Floo to the Leaky Cauldron. It was only a few minutes after their arrival that they were in the Alley and walking up the steps to the bank. They stood in line for only a few minutes before they were taken to one of the back offices to wait for a Goblin of the name Irontooth.

The Goblin in question arrived a few minutes after they had settled down and asked them a series of required questions such as to why they were there and where they found the child. He then took a few drops of blood from a very brave Hadrian that only made a small sound of his comfort. He mixed the blood drops in a potion that Severus recognized as a parentage potion that works on enchanted parchment. With a deep breath Severus watched Irontooth pour the thick potion onto the parchment and watched as it seeped into the paper.

It took a while for the parchment glowed a soft gold color signaling that it was finished analyzing the blood and creating the family tree. Irontooth picked the parchment up and read the name of the list before barking in gobbledegook to the guard standing just inside the door. "According to this parchment you have in your arms the Potter Heir," Irontooth said after the guard was gone to do as he asked, "I've called for the Potter Account Manager to explain why the Heir to Potter was found abandoned. You see here in Gringotts we have a system being maintained by Gaia's Magic to keep watch over the Heirs of Houses. If an Heir dies we get notified, if an Heir is unable to have a child it is marked in their file, if an Heir is abandoned or is left an orphan we get notified. Every Goblin is notified of the marks so if someone comes in like yourselves with an Heir that is not theirs we can easily help the Heir and the family. With this we have had no notifications and it is a grave mistake that we were not."

Severus and Lucius looked at each other shocked before taking a look at the small boy in his arms. He would not and could not believe that Lily, his best friend, would abandoned her child. Something must have happened and he needed to know what it was.
