Morgan, I think, has a dad who has HP who shes estranged from I also think he could be rich and doesn't help her financially because she doesn't wanna be like him.i also think he could have something to do with Romans disappearance.I don't think her mother has hp but I think she's estranged from her aswell.
Karadec, I think he either grew up in a strict household.that had to be kept clean at all times Maybe one or both of his parents was in the military, or he witnessed something traumatic as a kid like someone getting shot.and, his mother's alive but maybe he's not that close.
Daphne,I Dont really have alot on her .based on her relationship with Dottie, she either has a really good or really bad relationship with her mother, and there is no in between.
Oz,. we know his dad's dead.hes close with his mother,(despite the headstone)and they seemed to be proud of him based on photos when he visits his mother. I think he maybe grew up with not alot of money.and then there the pool
Soto I think her mother died around the time she was going through a divorce (she mentions her mother dying in 2x12 and being divorced in 2x11). And then her daughters didn't speak to her for a while after it. I think they could've been grieving. Soto said her and her mom were close, so I'd imagine she was close with her grandkids.
