I think Peter's first thought would be "I...I'm still alive?" And his second thought would be "Why? Why, God? Why won't you let this torment end? What do you possibly have to gain by refusing to allow me to finally move on from this misery? I can't keep on going like this. I just can't. But you won't let the pain end" and then sobbing quietly for about ten or fifteen minutes.
You're probably right about Ace's thoughts. Right after the Ack, he'd probably get up from wherever he was - in the mangled remains of the car, from a hospital bed or from the shallow grave he'd been dumped in - and continue on to whatever his destination before the crash had been, even if he'd been in a coma for a while.
Thoughts on the Talk To Me video: I also noticed the constant shining of Ace's shoulder armor. I did miss Gene's crotch moves because I was focusing on his facial expressions at that moment, which seem to be a cross between Animal from the Muppets and the acting style of Donald "Ogre" Gibb from Revenge of the Nerds.
The Youtube comments point out Ace's wink and kiss move towars the second half of the video, which is high quality. I also like Ace's patented head shake move, which he does often enough that I assume he's counting off in his head how long he needs to wait between spasmodic head jerks. Gene may have only given him permission for so many.
