Sebastien silently came in the library and nodded to witch. He came here often even before his unplanned trip so that he met most of the librarians. Not that he wanted to, they just started to jump out behind the shelves, asking did he need a help with something, and they did that so often that Bastien started to carefully open the books, waiting for them to jump out of its pages. He always said no, but they keep doing it and he couldn't do anything to stop them, at least anything which would not result in exclusion from the library, and this slytherin couldn't allow it. Sebastien needed the library, now more than the before. If there is a cure he will find it here, on this shelves. And there must be a cure, he couldn't let himself think otherwise.
He wore a long coat, not because he was cold, actually it was too hot underneath, but he wore it to hide his limping. He was still hurt but he needed to came back to London, and wizard library was his first destination. Sebastien thought he first need to fix himself and than find his brother, he's somewhere in London, he said it to him into Christian's last letter. The one he didn't have time to respond. They caught him a few hours later after he received his owl and send him back without answer, he didn't have time to write it, he was too close reaching his brother's goal. And when they caught him he wasn't in position for sending a letters, he barely lived.
Bastien went through the library searching for letter "W", he wasn't the one who was obsessed with werewolves, it was his brother, with werewolves and ways to kill them precisely. This one knew only primary things he learned on DADA classes. He couldn't just ask his brother for answers, it would be more easier but also more dangerous way. Christian would maybe started hating him, and he couldn't let that happen, there must be some cure.
His brother hated all werewolves because they killed their mom, and wanted to kill the whole group which killed her. Maybe even all the werewolves, he still couldn't count himself as one, although he was, Bastien knew it for sure, after his first full moon has passed. On the other hand, Sebastien didn't hate them nothing more than he hated the other people. They are fine as long as they leave him alone, same works for people, too. He didn't want to kill his mother's killer. That wouldn't bring her back, he would only risk his life for nothing, and he was certain she didn't want it. But, after what they did to him he wasn't so sure anymore. Sebastien can get over a lot of things, but torturing is not one of them. Or turning him into a werewolf.
He stopped in front of few books about werewolves, pulled them from the shelf and started walking till the nearby tables. Bastien sat for the last empty table and put the books on a chair beside him. He took the first one, 'Werewolves through the British history', written by some Irish author, and started reading.
