Probably the reptilians. Or maybe it was Bigfoot.
On the other hand, it could be that someone was infected with a highly contagious disease, didn’t realize it, and showed up to an event where everyone got way too close and it spread like wildfire. But really, how likely is that? Probably Bigfoot.
Yes it COULD have been that, BUT someone that was that HIGHLY CONTAGIOUS would NEVER have gotten past the testing or gotten in at all SO your scenario is actually very UNLIKELY!!
Perhaps my tin foil hat was on too tight today. I’ve been looking under every rug since the Biden-Wallace tag team match.
