Y'know, the friend I got stuck there with reacted pretty much the same way. You'd probably get along with him really well, he's a huge nerd. I say that lovingly, of course. He's never built a sweet sewer lair, though. Well, as far as I know, anyway.

[SIGH, nerds. ]

Most of the robots were still online and kept the place... well, not clean, but it wasn't a complete disaster. They had a whole busted space station to work with, which was abandoned by the same dude.
