His brother's reaction was a bit... rude in my opinion, but I suppose that is cause of his age.
He could've at least said something nice tho, like that's fine, I still love you, etc. Not just 'can I go and play on the x-box'.
He came out to his kid brother in front of a camera crew. How would he not resent Tom for essentially using him as a prop in his documentary & putting him on the spot for the sake of personal narrative?
Edit: And why is this coming out, years later, with zero precedent? So attention seeking.
