How do you think Sebastian would react after getting released/escaping Azkaban and finding out MC was pregnant when he got sent away?

Alright so i thought this was gonne be way harder. But i jumped on this so fast.

Warnings: A little angst. Implied depression/ptsd.

Obvious implied Sebastian × MC , implied Ominis x MC.

10 years. Its been 10 years since MC reported Sebastian for Solomon's death, getting him sent to Azkaban and ripping his heart out in the process. 10 years, and he was finally getting out. He thought about this day countless times. Though about getting to see MC and Ominis again. Thought about getting the revenge he deserved. Thought about ripping their hearts out. And now he finally could.

He may have to crucio a few people to get their location, but it was oh so worth it. His vengeance and hurt numbing him to others pain.

He walked up to their shared house. Oh how betrayed he felt. Is this why they sent him to Azkaban? The sheer idea of it setting him ablaze. They would get whats coming to them.

He peeked inside the window and was shocked at what he saw.

MC was braiding a little girls hair as she smiled happily, Ominis sat across from them.

In that moment all Sebastian could do was watch. His anger giving away to curiosity. Whos kid was that? Had they had a child together while he was rotting away in Azkaban?? The idea killed him and he found himself unable to breath. Not tonight. He can't do it tonight. But he resolved to come back tomorrow. He MUST have justice for what was done to him.

And he did return, the next night and every night after. But found himself unable to do anything but watch. Watch them from the outside while they were so happy together.

He did notice from all the watching that MC and Ominis didn't seem to be.. intimate. Their relationship seemed more like one of platonic soulmates. They were always there for eachother but not in the way MC and Sebastian were. But if that were the case then whos child is this? Who had MC had a baby with? Who would she? Other than Ominis, and that seemed to be very nuch not the case. The idea of MC with anyone else still set a fire inside him. After everything, even when she turned him in, he couldnt help but love her.

His thoughts were cut short

"Hi! Who are you?"

He turned around slowly to see the little girl hes seen every day for the past month

"Im.. and old friend of your parents"

"Nice to meet you! If you know my parents.. does that mean you know my dad?!"

He took a really good look at her face for the first time and noticed something.

She had curly brown hair and freckles all over her face. Brown eyes too. Curious.

"Ominis isn't your father?" He knew the answer to that already. Why did he even ask?

She laughed "no, of course not! Hes my uncle! He just stays with my mom to help out. She gets really sad sometimes"

He hated the idea of her being sad. How could he have ever wanted revenge? She didn't do this to him. He did it to himself. And he dragged her into it like he always did. He should leave them alone. Stop watching them. Let them be happy.

"Oh! My names Anne by the way! I just realized I never told you" she held her hand out to him.

Then it dawned on him. Oh merlin. How could he be so foolish. Anne..

"How old are you?" He asked taking her hand and shaking it lightly.

"Im 10!" She beamed.

It was like he was hexed. His mind swirling wildly. It can't be.. but it is.

"I.. i have to go. But it was a pleasure meeting you Anne"

He decided he would be back tomorrow. And not just to watch. He had missed enough. He wanted to be with his.. daughter. And MC, and Ominis. Every ounce of anger and betrayal gone. He would be back tomorrow.
