And, as someone who's been a social worker for years...
HMMMMMMMMMMMMMMMMMMM.
Also, I'd expect this to end up in a short term residential trip to an opportunistic "let us help you help your kids" mental hospital and a diagnosis of ODD...probably all due to the parental issues, which will be completely ignored and unaddressed, especially by the parents.
I know everybody has their own 'if that had been my dad...' contribution, but if that had genuinely been my dad there the kid would be on life support and disowned from the ENTIRE family.
I love you dad.
