Ha ha. I'm glad you grabbed that. Most replay coverage of the debate doesn't show the other side's reaction. I was hoping someone else noticed Joe's surprise about the tapes!
That thought crossed my mind. But as someone whose father died of Alzheimer's, one thing I noticed is their inability to hide their emotions. I actually feel like it was an un-scripted honest flash of recognition, almost like he'd forgotten about "the tapes" and was just then reminded of them. Certainly, Joe recognized that Trump is making a very clear allusion to the fact that the tapes will be released. These satanists seem to be operating under the illusion that the evidence will never be released. I'm convinced much (but not all) of it will be released, and that is still terrifying to Joe and his friends. Joe just can't hide that terror anymore.
