"I... guess so. I mean, we could brute-force it, but that tends to only work if you know how many 'doors' you need to take to get out of the loop," Simon replied. He pointed at the doors, going clockwise from one end to another. "It's simple math, when you think about it; Take the amount of doors there are in the hallway -- minus the one you used to enter, which I [I]hope[/I] will let us out again --, then multiply it to the power of X, where X is the amount of doors you need to take to get out of the hallway. Of course, since we don't know how high X is, it might as well be infinite. Not to mention the possibility of there being some secret to it before it will work at all, in which case we can try our entire lives and never get past this room. And the fact that this place is disorienting as all hell." He fell silent for a moment, then continued. "Either way, that seems like a bad idea; let's go back outside. ...I'm sorry, but do you still know which door we originally used to enter this hall?" 

On the way back, Simon spoke up again. "On the topic of strange science-fiction things: That reminds me of this game I once read about. Well, it's not so much of a game as it is a playable book, but details. Anyway, it had a really strange concept of time travel. In short, time was drawn like a tree. As you went further up the tree, more and more options became available. In some cases, you'd need to see an event in one timeline to even be able to change one in another. Which makes sense, when you think about it; how else would the character in question know what to do?
It also once mentioned that the way we normally see time -- as either a single line or a series of disconnected dots -- was similiar to a tree in 2-D. If you look at a tree in that fashion, you'll only see randomly placed dots. When you go to a higher dimension, however, you'll see that everything is connected, and that the future can even influence events in the past, much like how lower branches can be moved by pulling a higher one. ...To be honest, thinking about it too much makes my head hurt -- ignoring the fact that my head keeps hurting today, period. Does it make any sense to you?"
