Given that it isn't really Pence but Sam(check flight logs and call signs, at some point planes with 'Pence' aboard change their call-sign to SAM239, the evidence is there for anyone that want's to look it up) and he is following a script(amazing actor...).

If a video of Pence's confession is released there is however a good chance that it would actually be him from back when he was still alive and before he had been execute for treason...
