He has a short tempered, he doesn't really open up to anyone, and calls people nicknames like "loser" "nerd" and stuff around that. He isn't good at expressing emotions and he normally gets angry easily. His normal tone when talking is aggressive, but just like any human, he can be calm when her wants to be. He shows that he cares in his own ways, not much by words, but more action wise. He also uses sarcasm and humor a bit.
