Even when he struggled all his life to know the answer to the question of what made him different from others, why he was different and who he actually was, he never expected an answer so disappointing. He always thought something was very wrong with him and there was a demon inside him that controlled him and his actions but hearing that he was a werewolf was not what he wanted to hear.
Not because he thought that the demon inside him was more powerful or that what he actually felt and dealt with was commanding and should’ve been called something more ferocious but because he knew exactly how ferocious werewolves were. He had seen few movies to know that they were not looked at as kind creatures. He was disappointed because even though he knew his demon was something wild, he still hoped that it would be something softer. Maybe an angry angel or something. But not a werewolf.
