I think the discussion is over then.
I sincerely wonder what traits have been copied.
Mannerism, well look at little children, mannerisms can be there long before there is any label attached to the child.
So I don't see where the kid copied it. And how it is that the kid copied it willfully, though maybe not knowing, from an Aspie he never saw.
This is magic that goes beyond my wildest imagination.
So, I call it a day, unless you can make it clear to me.
