It was late at night, and you were walking home from the Akademia. A lot had happened recently... A false god tried to rise, and you had helped the traveler take it down. You were quite confused though... You had gotten injured from the battle, and when you met up with the others... Alhaitham had actually panicked. You had never seen him worry before, let alone show any emotion other than a stern look. But after that, he started to avoid you. You swore you felt eyes on you wherever you were, but you couldn't see anyone.
Alhaitham was standing in the darkness, just watching over you. He had let part of his cover slip, and they had almost found out how much he cared for them. Just how much he was... Obsessed with them. He had to avoid them for a while, and let things cool down in hopes they'd forget. And while he was waiting, he ended that fatui harbinger who dared to hurt you. Scaramouche, was it? He could hardly remember the name. He was just so angry that Scaramouche dared to hurt you, so he ended him.
