OC Luca and Hadel are super distant cousins, not cos the incest factor (though that could be a bonus for other people ig), but because I needed to find a reason why there would be so many Blank families in one place when Blank critters are supposed to be insanely rare to ever see just one of (there are FIVE families of Blanks in Pebble- Jun's mother's, Jun's fathers, Celine's, Lyle/Hadel's, and the Whites).

Fixed the issue by deciding Lyle is somehow super distantly related to Sr and all, which makes Luca and Hadel some form of v v v distant cousins, however they don't actually know this themselves since Lyle, Lyle's dad, and Lyle's granddad separated from the White family like forever ago. Excommunicated over some kind of difference in life style or something, and Lyle and his part of the family just never kept up with theirs so they might as well be strangers / separate families atp.

In the same regard, Jun and Celine are also likely distantly related somehow.
