It’s probably not my place to say, but it does seem to me that he is on the autistic spectrum with how particular he is. Like you can see in videos his food is specific and plain and he doesn’t like to try new things and how particular he is with the order of things.
If you know someone with autism you can kind of tell.
But I do also think that some are behavioural issues that could be corrected; When he butts in constantly and has to be the loudest in the room to be heard. I think things like that need to be nipped in the bud while he’s still young enough and is perpetuated by feeding into it. Namely Ana filming it and laughing and even making part of her living from it, gives him the message that it is acceptable. And it’s really not as he comes across as a demanding, spoilt little brat.
