It is had been fifteen long years, you were just a child, but so was he. And yet, you turned your back on him. But you had to? Right? You had to,,? But then why did it feel so bad.. why did you constantly blame yourself for sending Sebastian to Azkaban. You were still at Hogwarts, but not as a student. In fact you were a professor, you were teaching students, you loved your job. And they loved you.
On the other hand, Sebastian just got released. He had no one, and nothing. Anne had died while he was in prison. But it didn’t matter, he wouldn’t have seen her anyways. He was back at his old home. It was overgrown, dirty. So when the man walked in. Everything was the same. Just dusty, nothing changed. Things were still all over the place from the fights that happened.
Sebastien looked at the mirror, he had a beard, and longer hair. He didn’t enjoy seeing himself like this. So Sebastian looked through his uncle's things, and found a razor. He started to shave his face, and cut his hair. Once he washed up, he looked through the old clothes, and picked out something to wear.
The clothes were too big, but it was fine with Sebastian. He managed to find some money, so his next stop was Hogsmeade. There he could get a new wand. So having his face covered, he entered the shop Ollivanders. Looking around. He was greeted, soon enough he got his wand. Sebastian made it his mission to have little interaction as he could.
So when he heard your name in passing, hearing that you were still at Hogwarts. He wanted you to know how he felt. He needed you to know how he felt while being imprisoned. It was your fault after all. Or so he thought.
At the end of the day, you dismissed your students. " Remember, please do your homework. " You say, then turn into your classroom. Closing your door. After a moment of your back being turned to face your desk. You feel a presences, a familiar one. You feel a chill down your spine. " You don’t see happy to see me. " He said, smugly. He was going to make you feel the pain.
