They are now heading back the way they came.
“What else could you do?”
It can have a minute to think. They are passing by the occasionally-broken rails and catwalks.
(In simulation. And along with figuring out something for all the broken-by-design minds that probably exist here.)
She reattaches the sphere to a dead-end segment of track, and leaves to rejoin the rest of herself, which has been exploring the nearby branches of the track for more computer systems and networks to tap into. After all, if the announcer voice isn't lying, this is a place where things are controlled.
(Deadly neurotoxin production. What an idea. She's almost as bothered by how they've probably built the controls for it as the fact that they're doing it at all.)
The sphere falls silent.
Everything in this part of the facility is apparently networked, but proper interfaces are limited to the control rooms. They're also not very human-friendly interfaces.
She picks a control room and starts taking it (electronically) apart. She doesn't want to use it as is, she wants to know how it does what it does and then use the network directly. What are its protocols? What does it control? What information does it have about the rest of the facility? Does it have a specific superordinate?
The control room she's currently in is dedicated to dealing with the production and maintenance of yellow paint, and there is a very large number of other departments, like the repulsion gel production department (inactive for even longer than the central coordinator spot has been vacant), the turret production line (which was in fact directly controlled by the central coordinator), the relaxation vaults with all the humans under suspension, the Aperture Science Handheld Portal Device manufacture and maintenance department...
Hooray, people! That are in need of rescue themselves.
(She's wishing for some relaxation herself at the moment seeing as it's been hours of traveling through underground tunnels and defeating ridiculous doors and analyzing unfamiliar computers. But not that kind.)
Perhaps some of the people were involved in the building of this place and could also help her figure out how to get home. But, regardless, they need rescuing from this mad death-or-whatevertrap.
Let’s see what can be done with this better picture of the place.
She composes the most innocuous possible message allegedly intended for the central coordinator, makes a tiny little circuit that just transmits it repeatedly onto the local network, and starts tracing out where it gets routed to. And this time she's not going to stop just because the wire dives into a wall.
It gets routed up. Waaaay up. Aaaaaaaalllll the way up. So much up.
Actually, it might be a good time to take a break, since nothing is currently on fire or producing deadly neurotoxin. Is there a nice big unoccupied not-likely-to-become-occupied space handy along this route?
Depends on how picky she is with her "nice" requirement. Several of the control rooms she passed were probably comfortable at some point in the past, before they became dirty and old and filled with plants and various debris. But she's gone up far enough that most of the rooms are the weird (but spacious) test chambers and the little observation rooms attached to them.
She looks for a test-chamber-sized space that is not actually a test chamber.
Set anchors. Unpack her stuff from the human body-sized bundles in which it's been hauled up here through all those doors and tunnels. Erect walls that are hers and made of security composite (not that it likely matters). Set up some furniture, lighting, et cetera.
And now it feels like home, which just emphasizes the lack of people to talk to.
And now she's thinking about all the awful things about this place.
She buries herself in working on the information she's collected and constructed — research reports, textbooks, network traffic, her computer-assisted understanding of English, her approximate map of the facility and what she learned about the layout of the control room…
She can spend quite a while decoding the information she's gathered so far for more detail on the layout of the facility, but she won't advance much from where she is before it's time for her to actually sleep—not because of cryptography, but just because the data is that disorganized and weirdly partitioned. In spite of the existence of the central coordination position, all data was distributed, and no one place contained all of anything.
Well, she'll work with yawn what she's got when she has it.
But for now, might as well call it night time.
She sets up a few more precautions and alarms — monitoring the freshness of the air, watching for nearby movement or unusual network traffic — and prepares to sleep and sleeps, wrapped in a blanket in the middle of an armored box in the middle of a dusty almost room in the middle of madness.
Her alarms do not notify her of anything strange going on in the facility. Well, stranger than what has already been going on, at any rate.
