“I think this is planned, so they can claim all his stupid mutterings are jokes.”
When I watch, and listen to the crowd I get this:
The crowd started tittering because they thought Joe made a joke when he said “720 years”. Joe had no clue he had said that, and so thought the crowd took his remark prior to the ‘720’ as a joke, which is why he said he was serious and not joking.
What you have is Joe with dementia and the crowd is catching it from him.
Any “crowd” that goes to worship this demon skinwalker is already demented.
