Reference:
Bear with me guys but this is a theory I have, that in my opinion, sounds reasonable.
Last round, Kesler87 was The Punisher. He had the power to kill twice the entire game. According to his post in the thread, he was targetting PPCLI.
Let's assume Kes sent in a kill for PPCLI (I don't think he'd forget, he's takes this game fairly seriously + this is the 100th game). According to the original post, Villain kills will resolve last. I'd assume that means they are last on the kill order.
If that were true, that would mean in addition to being Villains kill target, he was also role blocked by a Villain. My guess is PPCLI had/has a key role for the Villains and they couldn't risk him dying early OR they didn't want to lose 2 Villains in one round.
Just my theory.
