I wouldn't be surprised if the vote was for something next year while Astrid was always intended to be the winner this year. Lisette insults both Bert and Rodrigault if you vote for them, but is a lot more supportive about you choosing Astrid.

Besides, I feel like they wrote up the joke of "Astrid's advice winds up causing Ywain to hook up with the crazy Central Shroud elf" in advance.
