First, shouldn't massive plot changes be the province of Gummies who is our resident Games Mistress?

Secondly... Uhm... so these beat cops, their patrol takes them to the nth floor of a hotel building where they just happened to overhear through two inches of wood? Officers do not patrol the upper floors of buildings, not unless there's a VIP worth protecting or the President's limousine is moving through the neighbourhood. Not only would these officers not be there, they'd promptly be sued and lose their badges for busting into a hotel room without probable cause.

Unless these were cosplayers dressed up as police... but seriously who does that?
