From his, albeit illegal, Earth visits, he gained decent information about personal and familial dynamics to some basic degree. It gave him both the capacity to transition as well as to assign a deeper relationship with the one, and only, chalcedony class gem he’s actually mostly trusting of. By technicality they’re siblings from emerging from the same kindergarten, but he moreso calls her that for the bond they have. As of right now she’s the only one that can tolerate him and his quirks.
White Agate belongs to @daikaiju-danielle (who is way a-okay with this~) She gets a lot of perks~ Nickname privileges is one of them!
