Announcer: WARNING: core overheating. Nuclear meltdown imminent.
Wheatley: I let him keep his job. I'm not a monster. Ignore what he said though, just keep on testing.

Wheatley: Might as well, you know, give you the tour.
Wheatley: To your left, you'll see some lights. Of some kind. Don't know what they do... ...but very sciencey anyways.
Wheatley: And to your right, there's something huge hurtling towards--- OH GOD RUN! YOU'RE NOT SUPPOSED TO BE THERE!
