Damien can be nerved quite easily, as he is seen to be blushing or sweating due to small factors. He's aloof, however, and holds a dark personality that can only seemingly be lifted by William.  Damien is shown to have deeper feelings for Will that go beyond friendship, and puts Will above everyone else. He usually blushes when around William. When William is kidnapped and put to sleep by Angela Wytte, Damien was the one who was able to break the spell by giving him a "true love's kiss."
