Oddly, I'm a little disappointed to find this setting to be the all-too-real SF, though with the extra wackiness that's going on, I'm sure I won't be disappointed for very long.

This chapter goes by a little quickly. I like how Amanda's changed since the intro, but I'd also like to see a little more time with her, to get a real sense of why Diego is so taken by her.

Likewise, I don't get a very good sense of Hatcher. I mean, he's kind of cool, just showing up and disappearing and seeming to know what's going on, and randomly helping Diego out. But who is he? I was a little lost in the action scene, didn't get a good feel for how fast they were moving, or just how dire their situation was.

The stuff going on around that scene was very good, though, and this story is getting very thick very quickly. Suggestion: That last scene, I would open it with something more like, "The room was cold, and dark except for a multitude of glowing monitors" and then launch right into the dialogue. You don't need to set the scene quite that much; not knowing exactly what we're dealing with will make the shadowy robot-things that much more sinister. :D
