We have to remember that Glirdan had to vote early. I must get that in as it looks like I shall also have to vote early.
My guess is that he chose to vote for Gil because Gil is notoriously quiet and hard to decipher anyway. Lhuna voted for Glirdan pretty much on the basis that he was the only one to vote so far. Gil voted for Glirdan pretty much out of spite. It
might be a tremendous place for Glirdan to hide (the very first vote) but I am definitely leaning towards Glirdan's innocence; and possibly a bit of foolishness on the part of Lhuna and Gil. Wolvish? I cannot tell.
