I have the feeling that most fans (me included) don't seem to be aware just how abusive Jacques must have been in canon.
He's a literally a merciless, controlling, sociopath treated his wife and children as accessories that only exist to serve him, and his four victims each display one threat response:
- Freeze (Willow sank into alcoholism and depression)
- Flight (Winter fled the family to join the military)
- Fight (Weiss wants to become an honourable Huntress to take back the family name from him)
- Fawn (Whitley lacks the ability to escape, so became his father's "mini-me" to fend off abuse)
The scale of the abuse is never really revealed, and he might have never done anything physical, but Willow did place secret cameras throughout the house in case evidence was ever needed, which says a lot.
Imagine feeling so unsafe for yourself and your children in your own home that you prefer to be recorded 24/7 just in case something
MIGHT happen (which could be considered paranoia, but I'm not an expert).
That shit is not the product of just some basic neglect.
That's a fun one.
Alternavely, what if Doctor Doom was Jaune's father (or mother), or maybe even grandparent?
Doctor Doom is pretty much a king, and it would make Jaune something of a prince.
Imagine the reactions and interactions that could happen when they find out that Jaune is related to the world's biggest benevolent dictator of an incredibly prosperous, completely self-sufficient and technologically advanced country (it might be pretty small in size compared to the others, but that doesn't change the odds when you have Dr. Victor Von Motherfucking DOOM on our side).
