Ya, he realises hes on live tv and just said the truth which looks bad. He tries to cover with his talking points but he was never smart to begin with but now his brain is oooooollllld.

https://rumble.com/vk6mkh-rambling-incoherent-biden-rants-about-aliens-and-the-man-on-the-moon.html When Don Lemon says he's had the vax, Biden says, "Are you OK?" What I see is Biden having a moment of clarity. He knows the vax is killing and maiming. The look on Biden's face is worry. His body language: head pointed askew and downcast, he doesnt wana look straight on with him. His jaw has a look of disgust. Eyes displaying worry as his sentence ends. The tone of Don Lemon's "yea" is quiet and resigned. He registers the seriousness of Biden's body language and vocal ques. Biden then realises he done fucked up on live TV and scrambles for damage control, "No, no it works, or, you know..." at this point he's panicking and tries to throw out tried and true talking points, but panic and cognitive decline are too much to overcome.
