In the trailer, who did Soren say strikes the final blow?

Ok, I went back and heard it carfully and it was Ezylryb. But Soren called him Lyze, plus that's his real name. Ezylryb: An old Wiskered Screetch Owl from the northern kingdoms, he was a talented warrior and later becamse a ryb at the Ga’ Hoole Tree. His real name is Lyze and he has became a famous owl in both the northern and southern kingdoms.This movie will be quite different from the book series. It's going to be a little bit different from the books. Movies are like that and I know why movies are different from the books that they are based on. Since books are copy writed by the authers, there can be no way for a movie to be exactly the same as the books. In other words, the people who make the movie will have to get the auther's permission in order to copy write from the book to the movie!
