Professor Filius Flitwick
1. Filius was prejudged and foredoomed from an early age because of his ancestral connection to a different breed and was both regarded and treated as second-class citizens by much of the wizarding community, by the time young Filius began attending Hogwarts School of Witchcraft and Wizardry, he was already used to being judged by strangers just because of that.
2. People used to underestimate him because he was really tiny and had a squeaky voice (still does sometimes), but they soon learned he was the best and most knowledgeable Charms master alive in the world.
3. Filius Flitwick loved being a teacher but because of the prejudges against him he didn't think it was possible.
4. He knows he shouldn't have had favorites but he did actually, have a few of them and they all ended up being troublemakers.
5. When Albus Dumbledore told him that he wanted to make a werewolf student of Hogwarts he didn't hesitate to agree. The same thing happened when Dumbledore wanted the same student to become a teacher.
6. He did ask once Helena Ravenclaw about the diadem she told him, she didn't know he didn't believe her but he never mentioned it again.
7. He was hurt more than he was willing to admit about the fact that Dumbledore didn't ask for him to join the Oder both times but at least he was able to help the second time.
8. He only learned of the Order's existence when Voldemort was reborn the second time.
9. Lily was a very beloved student of mine through different from many others he did found the Marauders quite funny.
10. He couldn't believe the fact that Lily and James were dead and he could believe even less the fact that everyone thought Sirius would betray them and, in the end, he wasn't disappointed.
11. He really shouldn't have been surprised that Remus was able to teach Harry the Patronus Charm so young after all Remus was a great student and became a great teacher.
12. Filius loved decorating Hogwarts during holidays especially Christmas as it was his favorite holiday.
13. Albus' death was devastating for him because Albus was one of his closes friends.
14. Flitwick had a good relationship with his colleagues at Hogwarts but he had dislike for some of the DADA teachers he didn't consider good enough to be teachers.
15. He did hate the fact that he taught many Death Eaters it made him feel responsible for every crime, they committed but he was proud to have taught Order members.
