So we know that Harley definitely voted against someone else besides himself... And that person can't be Fern because then there would need to be 3 votes cast to let this add up. So Harley was the sole vote for one of the other 3 who were not eliminated. This means that PDF did cast a self-vote, and received a vote from someone else besides Harley.
