I tend to listen to certain songs when writing about particular characters or places, so here I've compiled a list of people and places in "Daybreak". I think you should be able to find most of these on Youtube, if you're interested in hearing them, but there's one or two that aren't up there.
Some peoples' change frequently, depending on how I perceive the character. Luke's has changed at least four times this last week.
So, here is the list. And yes, all the characters show up at some point or another.
