So that's what the AI was so busy with. The test chamber lacked nothing; excursion funnels, thermal discouragement beams, aerial faith plates, everything.
A smile crept up on her face.
"Is that bet still going?"
"You bet it is."
"Let's start then."

The AI was full of glee once again. She had a lot of work to do. Now that her human was stuck in a test, she could put the testing pair to use elsewhere.
The testing pair were sent to the surface. They were given specific orders to gather wheat that had grown outside the shack. Even though she didn't dare to show it, she was genuinely excited about the new sense of hers; taste.
She had to agree, even when heated, the canned food supplements weren't going to cut it taste wise.
After decontaminating the plants, the testing bots went on to (try to) make bread. Even though they were given clear instructions, they managed to mess it up in multiple instances.
"Blue, that's minus five science points. Maybe you should try opening the oven next time."
She got bored of that quickly. She let the pair figure it out on their own after a while, and thought of something to do.
Initially, she was going to set up another chamber for herself. Then, other ideas came to mind.
This would be perfect.

Meanwhile, the test subject was struggling. She couldn't figure out where to retrieve a cube from. She didn't normally run into problems like this.
What she didn't know, is that GLaDOS had temporarily added a floor button when she wasn't looking. It was all part of the plan.
After letting her struggle for about five more minutes, she decided to begin the prank.
She was in her android body now, and currently behind one of the walls of the test chamber. She connected herself to the mainframe with a plug, and opened the wall. Behind that wall, she'd already put an excursion funnel, along with a cube.
On the opposite side of the chamber, the wall opened as well.
Already grinning with glee, she grabbed the cube Chell was so desperately searching for, and jumped into the funnel.
The test subject was already looking with confusion at the tractor beam, until she saw the android casually flying inside it. With the cube.
"Seriously."
The android said nothing, instead cracked and even wider grin and waved, as she was carried into the hole in the other wall.
She connected herself again, reversed the stream of the beam, and went back again.
What she didn't expect, was the test subject aiming a laser at her with a thermal redirection cube.
"Wait, wha-"
The android was shot out of the sky.
She fell straight towards a pit of deadly acid. It was at that point that she realised she'd forgotten to water-tight her android body. The android screamed as loud as her speakers would go, until she realised she was being carried in a funnel again.
The girl had caught her with a tractor beam. She sighed as she got out of the beam, next to the test subject, before finally saying something.
"You know, this body isn't watertight yet."
"I wasn't planning on dropping you."
"Good. Much luck with the test."
The android was about to walk back to a wall so she could plug herself in again, as the human cleared her throat.
The girl walked up to a button, while shooting two portals in different locations.
Snap. Snap.
She pressed the button, changed her portals again, and walked up to the android. She snatched the cube out of her hands, tossed it into the portal from a few feet away, and saw as the test completed itself.
The rest of the elements were already in put in place by her. The entrance opened, and the test subject portaled to it.
"Coming yet?" She shouted from across the room.
"I have to admit, that quick."
The android turned her back to the ground portal, fell gracefully backwards, and ended up next to the exit. Both women sighed almost simultaneously, as they realised they'd both have to cram themselves into the same, small, elevator.
They ended up chest to chest in the elevator, looking at each other awkwardly. Without saying a word, they left the elevator. They headed to their rooms. They would not talk about this again.
