Castiel does not feel the air himself, if only because he has not been conditioned to register or even think much of temperature. His vessel responds, but his mind is still very much that of an angel's. Even if he is cold, he does not realize it. Yet he still notices that Anna seems uncomfortable and he edges closer to her out of instinct. "I've never experienced love," he says bluntly. "But yes, it is complicated. Anger is...not thrilling. It too causes a discomfort in one's chest, but there is a sense of exhilaration for lack of a better term."
Yet, he supposes there are also positive emotions. Tilting his head to the side, he considers the fact that he enjoys waking to Anna in some form each morning. They still sleep sporadically and often, one is awake before the other, but there is something pleasing about the ritualistic sharing of coffee each morning. "I...like seeing you," he replied. "Our morning conversations are ones I find myself looking forward to. Despite the fact that there was chocolate in the cereal this morning, of course. I'm not sure I have the same fondness for it that you do."
He isn't certain why. He just knows its taste was not what he'd been expecting. "I'm not sure that can in any way be linked to an emotion."
