"Maybe I can help?" Buffy said quietly as she watched him pace. "I mean...I know some of the science behind it. Sort of. You're not a wackjob, Danny. It's real. A vampire is a dead body, possessed, animated and kept alive by a demon...of sorts. A wooden stake through the heart kills the demon. The body turns to dust because all the decomposition catches up to it at once...like a mummy first exposed to air. It turns to dust if they're not careful. Same concept? Maybe."

She started pacing with him, pulling her hair back with both hands as she did. "The problem is it's not all science. Some of it is unexplainable with science. You have to take it on faith and what you see."
