WATCH AT 2:12:00 0.25 SPEED
The camera is on the back of the last priest in red and you see W lean towards Laura and then almost SIMULTANEOUSLY W and POTUS turn to look at each other and POTUS seems to be saying to W with his steely look "You know what you have to do now so buck up and do it. I know it's the worst moment of your life but you know you are doing the right thing". W appears to acknowledge what POTUS is indicating and turns back forward and dreadfully waits for Laura's reaction.
BO, I've just watched this over and over at slow speed and I now believe that anon is 100% correct. W has flipped and is about to bring the entire house down. I wouldn't doubt that W will even admit to his father bringing him to Dealey Plaza as a young lad and gave him a front row seat to witness the moment that changed America forever.
