his kids are probably going to be messed up now with what they have been told from their JW grandparents and now their new step dad.
I doubt he is mentioned much other than them going over there and what they did there. By all indications Dijana seems to be a good parent and her parents aren’t likely to want to bring him up with all things considered. Lloyd can’t help tame his abusive and manipulative nature and they’ll figure it out if the internet doesn’t get to them first. The best she could do for them is to create a stable and nurturing environment and let the chaos and dysfunction that surrounds Jabba the Hutt speak for itself.
I can imagine their primary complaint about their father will be his disinterest in their lives and his obsession with a religion he left years before they were born.
