Wherein we have a very informative exchange with an advancement artificial intelligence, that reveals most of the plot.

P.S.: Sorry for the slightly cracking audio. This is perhaps because I accidentally plugged in my Xbox 360 controller before recording (if you wonder what this has to do with my audio—that's a long story). Either that or my microphone is starting to fail me.
