So, the original Kimmel died and they cloned him, he died again and they cloned him, and he died again, so they made clone number 4?

Yeah, very much like The Prestige, you see it?
Apparently we're on Jimmy 4 at this point, and you can kinda tell now that I think about it. Based on body language alone, Sal certainly seems suspicious (cocked neck, curled lip, etc.); and the Mexican Ed McMahon, there's just a whole different tenor with him - like he somehow
knows Kimmel 1-3 were drowned in a backstage tank.
Thing is, though, how can we be sure breakdown/grieving Adam is really Adam, right?
