I don't know, but I raised two and it sounds like a rage scream to me. Absolutely fucking livid. I think he does it often- we saw the beginnings with the scream singing and the 'mine' shrieks. J$ has found his will, he can't articulate well- but volume he's got. Dim kept Gin from going right away, she was afraid to anger him, because Dim wants the control.
J$ has no self modulation because his parents don't understand the concept themselves. They either fake fawn for a camera or he doesn't particularly matter and disappears. I think Dim is a much less involved father than he pretends. He makes a show of his night/morning routine. That may be the only time they genuinely interact at all now that J$ has a will. Dim is always out the door for stupid shit. Gin just doesn't know what to do as the fearful weakling she is. We give her shit for being neglectful but it's Gin who reads and plays with him daily, she's just bad at it and gets overwhelmed easy. I think that's why she sleeps in, in truth. She was never meant to be a mother and has no real support.
I don't believe the narrative that it's mostly Gin's fault. I know, I know, even it looks that way.
My gut says otherwise.
This is all orchestrated by Dim. That live gave us a taste with the mask off. He's more of a rigid cold fish than he pretends. He cares about the money and his fame. He doesn't care about raising the kid.
He decided they would have them. He wants workers. That's why he tracks her period, she pretends it's because she's flighty. She isn't. He controls the situation and becomes a monster if his conditions aren't met. She has employed weaponized incompetence to keep him from his own control freak raging. That's what I think is actually happening here.
J$ knows this and he takes his anger out on her more often...but he feels
betrayed by Dim.
I could be totally wrong, but this is the internet so of course I'll make as many wild assumptions as I can.
