Wow! Thank you so much to LRW, ShadowDragon1553, EmeraldTulip, Bye Felicia, and AlienGhostWizard14 for your comments and interest in this story! Was not expecting it!

Okay, so as you can probably tell, this is not a one-shot anymore. More ideas came, so now it's gonna have more chapters than intended.

A few things before we start. First, take note of the year Leo was born. It establishes the setting of this universe a little better. Second, take everything you know about the Davenport mansion - the rooms, the layout, the location, etc. You have it? Good. Now throw all of it away and imagine a beautiful, modern house that befits a billionaire. Construct one in your mind, and whatever you come up with, that will be Donald, Tasha, and Leo's house.

Lastly, as noted in the revised summary, this AU will crossover with multiple other fandoms. Before a chapter begins, it will be noted which fandom will be included, if any. This one happens to have a character from NCIS. If you've seen the show before, you'll know which one. If you haven't, don't worry; knowing her is not really necessary. This AU version of her was featured in a fic I wrote ages ago, where she and a number of others are also superheroes.

Apologies for the long intro. Hope you guys enjoy this one!

Past, Present, and How to Build a Home

When Leo Alexander Davenport was born on March 24, 2144, one thing was for certain: he was going to be spoiled. Although he was far from being the first child born to superhero parents, being the son and nephew of the team who had made much contribution to saving the world and eventually its acceptance of superpowered individuals gained him importance. The hospital room was usually crowded on his first day with well-wishers and close friends, the majority being either superheroes or high officials in government agencies of some countries.

It was a general consensus that the baby boy was adorable, and though it wasn't said it was clear that his protection had become a priority not only for Donald, Tasha, and Douglas but also for their friends.

As the months went by, the affection his parents and his uncle had for him only increased. Even now, as Donald held the five month-old, making what had got to be the silliest of faces to make him laugh, his love for him as his father was only getting stronger. Donald really wouldn't have thought that things would turn out this way for him and Tasha. When they were young, the three of them were told that because of the system installed in their bodies, it would be impossible for them to have children.

Not that they wished to have any at the time. They had only known horrible lives due to the scientists that imprisoned them. They didn't want any of their kids to be subjected to that.

However, years afterwards, after they were rescued and sent to families that loved them, things did get better. They gradually began to entertain the idea of starting anew and maybe one day getting married. Having no children was not such a problem. Actually, to Donald, all that mattered was being happy with the girl he had fallen in love when he met her again when they were teenagers. Douglas teased him to no end about his crush on Tasha, but he was positive that his younger brother quite liked the idea of his very close friend and big brother ending up together.

Then, after the biggest mission of their lives, Tasha went off the grid to take a break from the admittedly rattling ordeal. She was gone for years. When she came back, Donald found out that she had married someone.

It broke his heart in an unspeakable way, but he pretended to be unaffected by it. She was happy, and though she was with another man, he was glad for her.

He was working through these conflicting emotions when things turned for the worse for Tasha. Her husband left her. She preferred that, though, especially after she found out that he wasn't the man she thought he was. He wasn't Henry Jones, an unassuming, clumsy police officer who had lived in Florida his whole life. He was someone…horrifying.

He had fooled her into falling for him, and after he had vanished when she discovered the truth about him she was left disgraced and hopeless.

What am I gonna do, Donald? Tasha had cried to him a month afterwards. What are people gonna say when they hear about this? I'm supposed to be one of the smartest humans in existence. How could I have been so stupid?

He looked at her sympathetically, hating what that man had reduced her to. It wasn't your fault, he had consoled. He tricked you. There was no way you could have known. Tasha, don't be so hard on yourself. You can just start over. He smiled a small smile then joked, Look at the bright side. Legally, you're single again. Being single is fun, right?

Tasha sniffled. She hesitated for a moment before looking him in the eyes. Her lips quivered as more tears came to her eyes. I'm pregnant, she had said, her voice barely above a whisper. I don't know how this is possible, but I am. I wanna keep the baby, but…how can I do this alone? What if he comes back to take him or her away from me? I can't do it on my own. And, how can I explain to my child what happened to their father? What their father is? How would they understand? And the agency – what if they take my kid away from me? This…this is not what I wanted.

It saddened Donald to watch her break down in tears. He was so used to seeing her being strong and taking charge of any situation. Yet, at that moment, she was left feeling weak and helpless.

It kicked up something within him, something audacious and rather bold. He wanted to see her happy, and he was going to do whatever was necessary to make it happen. Then marry me, he had said.

Tasha stopped crying. What?

I said marry me. He took a deep breath before explaining, I don't want to be alone either. Tasha, I can take care of you, you and your baby. The three of us can be a family. I can protect you, too.

Donald…

No, I know this is a bad time to bring this up, so don't give me an answer yet. Just take your time and think about it, he said. Then, sincerely, he noted, How I feel about you has not changed. I still love you. All I want is to see you happy, even if you decide that that means not being with me. But, if you could, just give me a chance. Please.

Donald doubted that Tasha entertained his proposal at first, and the more he thought about it after their conversation the more he felt foolish. But then, a week after, Tasha came up to him again, tears absent from her eyes that time. What if I never love you back the same way you love me?, she had asked sincerely. I don't want you to live the rest of your life with a woman that can't return your feelings. You don't deserve that.

Her honesty surprised him initially. However, after pondering over it, he responded, If we can remain really good friends throughout, I'll be okay with that. As long as the two of you are with me, it'll be fine.

Tasha took a moment to process it. Then, she smiled at him.

It was a somewhat chaotic wedding. Since both of them allowed a few months to pass, dating throughout that time so they could get a chance to really know each other better, Tasha was eight months pregnant on their big day. It was meant to be a small occasion, but a friend's loose lips had caused the attendance of many acquaintances. It was rather stressful, but it was a joyous event nonetheless.

Not long after that, their son was born.

Even up to now, Donald believed he had stayed true to his promise. He had done his best to love Tasha and Leo. Not that it was hard: Tasha, contrary to what she had been afraid of, had been generous in reciprocating his affection; and Leo had been a constant source of joy for him. The boy loved him very much, and he knew.

As he playfully lifted his son up while they relaxed on the couch, he heard two sets of footsteps cross the living room. "Honey, please don't toss him," Tasha said as she stood by the door with her best friend, Kate.

"I'm not tossing him," Donald said with a grin as the five month old let out a high-pitched laugh. He looked at his wife after sitting his son on his knees then said patiently, "I know, babe. You told me don't do it because you don't want him flying high up in the sky. I listened to you."

Tasha smirked. "Not only that, but I also just fed him. He might throw up on you," she said. Upon seeing her husband frown at their son, she chuckled. "You think you can manage?"

"Oh, uh, yeah. Of course," Donald said as he watched the little boy nibble on his own fist, covering it with slobber. He smiled at her. "Just have a great time with your friends."

"Okay," Tasha said. She hesitated a little and took a long glance at her son, but in the end she chose to go. "Bye, baby."

"Bye. Have fun," Donald told her. To their mutual friend, he said, "Bye, Kate. Thanks for picking Tasha up."

Kate smiled. "Of course. See you later, Donald." She closed the door behind her. Soon after, both women were gone.

Donald turned his attention back to his son. "It's just the two of us left, buddy," he told him. "That's okay, though. Daddy's still here with you. You wanna come with me to my office to help me finish some paperwork? Hm? Does that sound good?"

The five month-old found the hem of his father's shirt more interesting, but he seemed to have no qualms about that plan.

Donald chuckled. It still floored him to think of the future he had now. It was far from how he thought it would be when he was younger. He was respected, a hero to the world around him, a husband with a beautiful, smart, and kind wife, and a father to a very happy child.

You're worthless. You'll never become anything. No one cares about you.

The smile on Donald's face vanished as that voice from the past rang inside his head. Those words were difficult to get rid of because Dr. Fox, one of the scientists that dealt with them when they were younger, said those to them so many times that they had engraved themselves into his, Douglas', and Tasha's memories.

Worthless, useless, and unloved. Even after all the hard work of his and Douglas' adoptive parents to get them to ignore those sentiments, sometimes they would come up. At times he would believe them. Maybe that was why he would usually overcompensate. He had moments when he would try to replace self-deprecation with egotistic thoughts. He didn't mean to be overconfident, but it was the only solution he could find to overcome those negative lies.

As if knowing what he was thinking, Leo stared at him, nibbling on his other fist carefully, watching how his father was going to combat the nightmarish thoughts.

A shadow of a smile pulled on Donald's lips. He pulled the little boy up to his feet, and then, looking him in the eye he told him, just like he had many times since he was born, "You're worth many things. You will become something. Many people care about you." He took his son into his arm in a warm embrace. "Daddy and Mommy love you very much, Leo," he told him before kissing him on his chubby cheeks.

Little, slobbery hands reached up to his face, and Donald knew it was his son's way of showing him affection, letting him know that he loved him, too.

The front door swung open then, and it sent Donald on alert. However, seeing that it was only his little brother, he fell back at ease. "You know, we installed a doorbell for a reason," he said as Douglas raided the fridge.

"Hm, desperate times," Douglas muttered as he took out a few containers. "I'm starving."

Donald grinned. "Do you ever not eat?"

"Try running at the speed of sound every day. You'll understand." Douglas was already in the middle of eating when he finally noticed his nephew. He grinned when he saw the little boy watching him with interest. "Hey! I didn't know you were up, little man!" he said as he made his way to them. Taking the five month-old from his brother, he cooed, "Hey, buddy. How are you doing?"

Donald frowned as his younger brother embraced the baby. "Oh, uh, Douglas – you may want to be careful with—" But Leo had already thrown up before he could finish his warning. Donald was inclined to apologize, but a grin came to his face instead. "You know, this reminds me of your party when you graduated college," he said as his brother looked down at his spit-covered arm with disgust.

Douglas glared at him. "Yeah. You threw up on me, too. Mom told you to quit drinking Dad's stuff, and you didn't listen," he said. Frowning at his nephew, he said, "You really are your father's son, aren't you?" He huffed but took the child with him to the kitchen anyways to clean up the mess.

Donald chuckled. His son's life was definitely going to be interesting with a family like them around, that he was sure of.
