It became apparent that after everything that happened in your Fifth-year with the Goblin Rebellion, Sebastian killing his uncle and you sealing away the Ancient Magic that now lay dormant under Hogwarts—the next two years should have been a breeze.
But unlike what you'd hope to believe, there is always much more drama—and despite accepting your choices, one of which you decided to not turn Sebastian in, life wasn't just going to go back to "normal."
You're Sixth-year was left to basically pick up the pieces—to fix friendships, to try and forget, but instead it just made you more aware of how much it had affected everyone and over time, everyone grew apart.
Now it's your Seventh-year—things are looking better, everyone even seemed almost normal again, all except for Sebastian. Truthfully, everything hit him the hardest, the guilt and the anger still bubbling inside him, but you were almost positive that you saw him smile that day he was asked to be the captain of the Slytherin Quidditch team.
It was hard to watch from the side lines—seeing Sebastian slowly become himself again, while you felt stuck, but it wasn't until one fateful day, when you both got paired up in Potions class, that you both had to either play it cool or finally confront the elephant in the room.
