The Sword of Summer question

I think that Magnus is a round and dynamic character in the first few chapters. One example that Magnus is Round is that he can be scared, or angry, or happy, or sad at different times. One example that Magnus is dynamic is that Magnus is now more confident. This is why I think that Magnus is a round and dynamic character. I think that Magnus and Fenrir are foils because, everything that Fenrir does has evil intent, but Magnus does things to save people.
