"If it is, then I'm as unaware as you are." Jack confided, as he remembered reading that book too. "Although it is quite an illuminating story, it wasn't the most helpful with determining just what the 'Christmas spirit' was, for my studying. I found it more to be Mr. Scrooge's fear of death motivating him, which is a common theme among mortals and humans. Especially their fear of having a bad one, as opposed to a good one. So his desire to suddenly enjoy the holiday and make it merry for others seemed rooted in a need to have a 'good' death eventually, rather than to honestly celebrate the season and regain his lost sense of wonder."

Don't mind Jack, he's not meaning to lecture. "I found "The Gift of the Magi" only slightly more helpful, though when trying to reproduce the results via testing on the presents themselves, the results were inconclusive."

Studying? He'd been studying Christmas? And experimenting on it, testing it, subjecting it all to science in an attempt to understand.
