Kallie's immediate family is already pretty well-defined, but you never know. Her father is a former stormchaser turned meteorologist; her mother is considerably older than her husband and is a retired aircraft inspector. While Kallie doesn't have any siblings, I'd be down for twisting things into cousins or the like! People or people with parents or whatever who'd know hers are welcome as well, of course. |D;;

She's in college now, tying up her second year of studying athletic training, so classes with her, living on the same dorm floor as her, etc., are all open. Considering she works at the campus' health center, it's possible those who would have any reason to go there for some reason may have seen her line-facing around. As an added bonus, her hair has recently started going pink, which is... noticeable, I suppose.

She's also indeed one of many who have attended the generically-named Locke High. Back then she kind of kept to herself though, if not necessarily an outcast- she was involved in cross-country and/or track, so there's that. She's also pretty much totally disinterested in romance/sex, so while it's a possibility she might have had a boyfriend at some point, it was probably short-lived and full of fail.

SO, YEP.
