Great tutorial and it was well presented. ^^ Although I had to search up this guy, despite that I used to be a massive Harry Potter geek and read all the books, I cannot for the life of me remember this guy in the films.
lol. He was in the beginning and somewhere in the middle of the Half blood prince also when The headmaster was killed he was there, the chase when Harry, Ron, and Hermonie were captured looking for the souls of Voldy in the Deathly Hollows part 1. And then at the battle in the last movie.
