The first thought I have about Louis is the whole “incarnation of time” thing. It’s incredibly fascinating to me that he’s a personification of probably one of the most recognizably influential forces out there, and has no clue. Makes one wonder what happens when he figures it out, if he ever does. Since he is time, could he ever control it? Speed it up? Slow it down? Travel through it freely, like he was walking through a park?
Louis himself is a big ol’ sweetheart, most of the time. Not in that naively trusting everyone way, but the kind of person who doesn’t seem to have lost faith in humanity, which is so hard to find, usually. Especially considering he has a couple hundred years on everyone. It’s really nice working with a character that isn’t all hardcore or cynical all the time. (Don’t get me wrong, that’s fun, too. It’s just nice to take a break sometimes.) And the story we have going on between our muses (if you ignore Cora trying to kill Louis - oops) is really uplifting. :D
TL;DR: Louis is awesome. Love him.
