Reno and Falyn Snow are Sierra’s adoptive parents.  They’re pretty cool and laid back, and that’s obviously imprinted on Sierra a bit.  It’s uncertain, however, where she got the barefoot thing from.  Maybe somewhere out there in the void, her biological mom is a flower child nevernude.

These… may be the penultimate batch of character models of family members introduced during this storyline?  I know there’s at least one more to go from a character nobody’s ever seen before, but there may be some others who might’ve already have character art drawn.
