Before the game begins, can you clarify this a bit more?

Because of the odd setup, the town victory condition is to avoid the lynching of the jester. The jester being the last person standing will automatically trigger this, and to avoid any unlucky final-round mess-up, the jester's vote will be a negative tiebreaker, meaning that someone with the jester's vote on him will always "lose" the tie (ie. stay alive).
