I really didn't want to mention it, but the scene when J meets Mickey and Mickey hugs him...he did more of the self-regulating movements again. He does the jumping around, and then really stiffens and arches his fingers/hands. Others have noticed this before, and I have definitely noticed the tensed finger motions before. I really hope they have his regular checkups and have noticed these things enough to mention to the doctor. It could be nothing, it could be sensory overload/processing, or something he will slowly grow out of (possibly solely based on nervousness/stress), but it happens in so many of these videos when they insist on these forced interactions with characters and people. I feel sorry for him that he has to have every interaction filmed and dumped into these vlogs. Not diagnosing anything or insinuating he has a major problem because nobody can do that from a vlog clip, but because his every move is filmed then these private moments are constantly displayed for everyone to see. Ugh.
