Well, take this for example. When I went to the elevator version of my town with Lucifer, he didn't know that it was a bad sign that the sports equipment was gone. He probably would've guessed that the robot guards and dogs weren't nice, but he wouldn't have known who made them, or just what makes them dangerous.

[pause] I mean, it wouldn't be a big deal for you, but if people were around you, you'd want to know that the robot dog will only tear you apart if you say the word "trouble," right? Nobody but me knows that.
