That's fake as shit. If it was real the whole family would be considered completely dysfunctional. Going to this level of theatrics and filming what is probably a difficult moment of contention in your own family so that you can put it on the internet is psychotic.

If this was real the only way to view this video as terrible parents who screwed up a long time ago, and are now making a sick video of their son freaking out losing the only thing that was important to him.

A normal family that has an issue with one of its members would sit down and talk about it and address the issue, and figure out a way forward that would be best for the son. That is what parents do for adult kids who have problems.
