From what little I have read and seen.. it seems VERY obvious to me that they cross over into our world and attempt to save their series from being cancelled. I'm not joking. Consider everything that has been pointed out and talked about and look at the description for the last episode: "Knowing they are destined to die, the Dwarfers head to a mysterious address in London to plead for more life." I'm gonna punch someone really hard if this is the case. But if it's so.. I CALLED IT FIRST!! WHOO!!
