Our group's chosen NPC from the card draw was Sir Godfrey.  Spoiler:  he is a knight of a fallen order who was killed by Strahd.  I have been playing up the chivalrous side of Sir Godfrey, so when he first encountered Strahd he launched into a short speech about how he had sworn vengeance.  So of course Strahd said:  "I killed you too quickly the last time. A mistake I don't mean to duplicate tonight."
