history: There was this giant spider in my room. I'm afraid of spiders. I went to get something to get it with, and I came back. The spider is now missing.
current: Oh great. There was a big spider in my room, so I went to get something to scoop him up with (or flatten, I hadn't decided between the two yet). I come back and he's disappeared. 
next: oh oh, so now you don't know where your enemy is hiding.  Sounds scary.
