[A/N]

Hi there! This is my second ever Fanfic, and the reason I'm saying this is because this is a direct sequel to my first. Some things might not make any sense at all, without having read Humanoid.

Reviews are greatly appreciated, and enjoy this first chapter!


It was Monday morning. She was proud to think that. Before, she was never shown any evidence of morning. She could wake up in the middle of the night and still think it's morning.

That was different, now.

She was in her new bedroom, up in space. It had taken a long while before she really got used to that idea. It was easy to come to terms with the fact that your home is miles underground, it was still on Earth, after all.

But to live in space? That was a whole different approach. It had taken a lot of talks with GLaDOS to convince herself that, no, she won't go crash-landing back down to Earth.

And it wasn't like she was in a giant, well-equiped space ship, oh no. She was in a little shipping-container sized box, separate from all the rest. That's how it worked here, in the Aperture Science Sky Facility; boxes, upon boxes, upon boxes. None attached, all of them floating freely.

At first, it wasn't very uncommon that two chambers would crash into each other. She remembered how loads of them broke because of that. There was even one to almost fall back down to Earth; she ended up saving the day with her Matter Manipulator device, teleporting it right back up.

She remembered everyone celebrating that night, (night, they had nights now!) lots of people cheering, and some even dancing. Not GLaDOS, though. She was just, in her respective chamber, working on a way to fix it.

Not more than a week later, all of the chambers came equipped with suitably sized rocket thrusters, along with motion detectors to trigger them. Pretty simple, really.

Well, it was now, anyways. In her Human form, she would never have cared about any of that stuff. As long as it worked, she would be happy with it. Now that she was part of the Humanoid, that was different. She could download schematics of anything in the Sky Facility, and understand it fully, without even trying.

It had taken months for her to fully get used to the fact that she somehow spoke binary, now. That was pretty funny, now that she looked back at it. Her natural language processor wasn't working properly, and she ended up actually speaking in ones and zeros for half the day, until GLaDOS got it up and working again.

She was pretty sure that was just an elaborate prank, but the AI kept denying it. Today, though, she was going to prank her back, regardless.

She got out of bed, and almost walked out the door. The girl turned red at the fact that she almost walked straight out of the airlock, not wearing anything. She still wasn't used to the fact that she had an internal heater, so she couldn't really tell if she was wearing clothes, or not.

After putting on a blue jumpsuit, which was the standard in the new facility, she pushed the button to open the airlock. The first door opened. She stepped in, and the door sealed behind her.

On the ceiling above her, was an excursion funnel emitter, third generation. She stepped under it, and it immediately turned on. The light was quickly snapping between blue and orange, or push- and pull mode, so that she was suspended in a sort of hover-state.

"Destination?"

The overly-cheery voice of the announcer sounded over a speaker inside the emitter, so that it could be heard, even when inside the funnel.

"Central AI Chamber." The former test subject answered.

The big vault door in front of her opened, and the excursion funnel emitter moved forward to peek out of the opening. It then rotated towards the big, Central AI Chamber, and turned blue.

These excursion funnels moved considerably faster than the ones she encountered in the test chambers, and were only suitable for transport. Every box, or chamber was equipped with an transporter like this, but a few people were still very anxious about using them.

It is quite a weird sensation, being suspended by a translucent beam, right above the Earth. She used to have nightmares about them failing. Pretty much everybody did, at first.

When the former test subject arrived through the airlock, she looked around for a bit. Nobody there. As usual, GLaDOS was in her manufacturing workshop, probably tinkering with the android fuelling systems again.

She was determined to remove the breathing mechanism from all androids. She hadn't found a suitable solution yet, many of them required regular recharges, which no one liked to do.

She walked down the steps, and with a simple thought, raised the receptacle. The former test subject connected herself to it, something that seemed like a taboo all those months ago, and prepared to transfer herself into GLaDOS' chassis.

/Unrecognised Source./

The words appeared in her mind, through the receptacle. Looks like the AI has protected it. Everyone knows you can't change your designated serial number, which indicated to the interfaces who you were. Only someone with the serial number zero could enter the chassis, Zero being GLaDOS herself.

She'd have to find another way of pranking her, then.

"What are you doing here?"

The android came into the chamber through the airlock.

"Nothing. I just woke up, and came looking for you, why?" That was a lie. She knew where the AI was.

"That's weird…" The android responded, with mock confusion. "I got a message that someone tried to log in to my chassis. Now, who could that be?"

The other android began to chuckle. "Alright, you got me."
