 John is the kind of person who generally does not get emotionally wavered by events that would drive others to the brink, but instead gets riled up and irrationally stubborn over ridiculous minutia, to the amusement or confusion of others. This is proven true on a number of occasions throughout the comic, as he is shown to react calmly and appropriately during some of the more traumatic events of their session, but loses his mind when he briefly loses interest in Con Air. He is very innocent.
