they were raised on alpha farm which is more or less a commune and weren't exactly given order or structure growing up. more often than not, the kids did their own stuff with little help or supervision. carinah really resented that and while i imagine she probably tried to help raise her younger siblings she also wanted out so she tried to run away at 14 and left for good at 17. her mom then moved out of the commune the following year and whether or not he left with her or stayed at the commune or even went to live with carinah would be up to you. their mom would have died in 2010 as well.
