There is no way that is going to happen, another fire would be too predictable. This time someone is probably going to drown instead... No wait I got it they are going to freeze to death. The librarian was introduced as the Ice Queen, so that's probably a subtle clue about how she is going to kill someone you are banging when she gets jealous
On a more serious note, did the last Josy render actually unlock for everyone? I beat the normal and hard difficulties during the last free roam, got the message that it is unlocked, got the phone icon to show an exclamation like something new was available...but nope still unclickable padlock icon saying had to beat the fighting game.
EDIT: Nevermind...did not notice the scenes under mixed. So apparently you have to beat the brawl game on normal every single free roam in order to unlock everything. That's somewhat confusing and annoying.
