Next up, Chell herself had a request. GLaDOS had proposed sorting out all of the books from old Aperture, but the girl had other plans. She refused to do anything else until she'd get some sleep. It was getting dark, after all.

The android has just given her one of the extended relaxation chambers. They looked a lot like a traditional sleeping space, after all. She'd promised to turn off the cryosleep systems, so she could sleep naturally.

She got back into her chassis, and went on sorting the many books and files they retrieved. She didn't have to sleep, after all, and shutting herself off for the night she found impractical. Especially when she could be doing science.

In the morning, when the girl finally got out of bed, the AI already had a plan worked her. She would go back to testing for about an hour, and after that they'd go hunting for leftover frankencubes.

Unfortunately for GLaDOS, the test subject had some requirements. First off, she had a request to make the test less lethal. She just delayed the reaction time for the turrets, and lowered the thermal discouragement beam's temperature, amongst other things.

Her second suggestion surprised her. She'd figured, now that she had an android body, she might as well test with her. Initially, the android was against it.

"You're just afraid to be on the other end for a change."

"You're wrong. I endured worse things after you put me in a potato."

"Nothing changed. You weren't the one solving the tests back then, you were simply watching. Now in what sense is that different?"

"In the sense that I feared for my life."

"My daily bread and butter. Well, I should've known that the 'most advanced AI known to man', is scared of some simple tests.", the girl said mockingly.

"Want to bet?"

"Want to lose?"

"It's on."

And so, they went on to their first test chamber.

She designed a pretty tough one, fitting for both the test subject's experience and the android's processing power. She did have to delete the schematic.

It was particularly annoying that she couldn't tell her partner what to do. Her programming restrained her from saying anything test-related. It didn't turn out to be that big of a problem, since, Chell tended to stay silent in the test chambers. That didn't stop her from snapping sarcastic remarks to her, like she always did.

This did result in her receiving a smack in the face. She wasn't expecting that one. The next test chambers, she was silent, too. It's funny how things work out.

She did have to create separate portal devices for both of them. Chell's portal device had two pink stripes running along it, with pink and green portals. She initially opted for just the regular orange/blue one, but that would've interfered with the portal she set up in old Aperture, which she definitely didn't want to set up again.

GLaDOS' gun had yellow stripes running along it, using yellow and violet portals. The two did have to get used to the colours, but it worked out in the end.

After a bit more than an hour (they'd gotten a bit carried away), they decided to move on to the next activity; Frankenturret hunting! They decided to keep their portal guns with them, for convenience.

"There! Over there!" The girl pointed at a catwalk above her with her portal gun.

The android shot a portal up to the catwalk, then beside her, then beside her, and walked through. The test subject followed.

"Just place another portal and drop it through."

The test subject's green portal was located right above an incinerator, a bit away.

She did as the android said.

"I think that's the last one."

The android laid her finger on the side of her head, indicating it was looking at its internal interface, instead of out her eyes.

"If the camera sightings are anything to go by, then yes, that's all of them. Stay on the lookout though, there might still be some left."

The girl did a small victory dance, followed by another remark from the android.

"Be careful. The catwalks can only hold up about 150 kilos of wheight."

This only resulted in the test subject jumping even more.

"As soon as you're done doing… whatever you think it is you're doing, let's get out of here."

"Alright, sure."

The android portaled lightly kicked another wall, opening it up, and connected herself again.

"I'm positioning your green portal back in the Central AI Chamber. Open a portal over there.", she said whilst pointing her finger at a nearby white wall.

After they got through the portal, the AI went back into her chassis.

"Although this is the last place I'd think I would say this, this was actually pretty fun so far."

"I'm glad you're enjoying your tasks", The AI said offhandedly.

A few minutes passed, the human sitting on the floor, and the AI still busy in her chassis.

"What's next, some more testing?"

"I think not. At least, not cooperative."

"Why not, you enjoyed that right? I think that was pretty clear."

If the AI could've blushed in her chassis, she would've been bright red. Her reactions concerning the solution euphoria had been…. Uncontrolled. In her chassis, concealing it was easy. She didn't have a bipedal body, and didn't need to support herself. That's why in the test chambers, she'd promptly collapsed at the end.

She knew how to control herself after the first few, but it was embarrassing nonetheless.

"You're talking about the testing euphoria. There's no difference between observing and actually doing it, concerning the euphoria. What you were seeing was the result of a poorly constructed bipedal figure, unable to support itself."

"You designed that body, right?"

"Yes, is that important?"

"Point made."

The human did have a point.

"…Anyway, your next task will indeed be, testing. On your own."

Before she could protest, the panel she was sitting on flipped up, launching her towards her green portal. The pink portal had been relocated to a test chamber.

In front of her now, was the biggest test chamber she'd ever seen.

"Good luck. You'll need it."
