"So you didn't tell me who's Cave."

"He was my grandfather. He founded this facility back in 1953. It was making…"

"1953? Shouldn't he be dead?"

"He is. But the Aperture Science employees resurrected him inside a computer, which means that he's sending messages to us literally from beyond the grave!"

"And how much nightmarish is GLaDOS?"

"Pretty much. She had that failure cake fixture. She teased me all the time while I was at the headquarters for the first time."

"So… should we go?"

"Where?"

"Right out of the facility!"

"I'd say no, but you're pretty cute, so yes. But first… where did I put my Aperture Science Handheld Portal Device?"

Wheatley wasn't listening. "Science. Again."

But Chell didn't search for it for long and said:

"Let's go."

But, unfortunately, she couldn't shoot a portal at the broken ceiling.

"The stupid metal walls… I think we might as well go through the door."

The door was as stupid as a normal door called a gate, but for Chell and Wheatley, that was absolutely normal. However, Cave was not as level-headed.

"They obviously don't know that they are going to meet the Pest Chambers of Death. I must inform them."

An Aperture Science Random Informer would like to inform you that you're now approaching the Pest Chambers of Serious Injuries. Please turn back now and cake will be served. Immediately.

"Cake? Don't be GLaDOS, Cave. Wait. Serious injuries?" Chell stopped just before she was about to fall into the spiky floor and put Wheatley down on the floor.

Oh no, you've mentioned Gladys. As I am a computer myself, I can't cry, but if I could, I sure would. That horrible night of 1986… The Combine all around… omnicoder's Portal Timeline… If only I knew we both would turn into computers… And then you… Passing through tests without a single mistake… And then killing her… And then… Oh no, not this again…

The stupid nature force affected Cave again, and some other voice Chell didn't recognize came on.

Important message arrives. You failed in your life. Please go back. I promise, there will be no cake. Shutting down and putting Cave on after an important message. Error: could not put Cave back on because the whole headquarters are decaying and nature is coming everywhere.

"GLaDOS! Now I'm really doomed. But wait… can I place a portal there? Yes!"

Chell shot a portal where appeared to be a floor, and carrying Wheatley, went through.

Now she – and Wheatley too – could see where they are, as they saw an infamous Test Chamber Sign. It read "Pest Chambers of Death – Chamber 01 out of 50". Underneath this sign there were some schematics that denoted that you could be shot down by the turrets or fall on the spikes. There was also a number 1 next to the turret schematic.

"One turret? It might as well be. And for the biggest failure of all time, I could even go backwards the chamber and see the turret not seeing me."

Chell, you must be stupid. It's a test chamber sign. And test chamber signs always appear at the start. Now I'll reprogram the elevator to go backwards.

"Of course. How could I forget. So, Wheatley? The elevator must go to the maintenance area. Come on."

"No," said Wheatley, "maintenance areas cause me phobias."

"Then go your way. Here's a rail. You should know your way to the Companion Cube Run. I'll wait for you there."

Then Chell stepped into the elevator and went down to the maintenance area. The elevator also was kind of stupid, but that's what the whole headquarters are. And then Cave came along.

Don't worry, I'll lead Wheatley to the Companion Cu… (garbled) Test Chamber Seventeen. And as you go, I'll tell a story. Don't worry if I rephrase Wallace Breen, but that's it. "Welcome. Welcome to Test Chamber Seventeen. You have chosen, or been chosen, to relocate to one of our finest remaining test chambers. I thought so much of Test Chamber Seventeen that I elected to establish Companion Cube Run here, next to the Aperture Science Wall Failure so thoughtfully provided by our employees. Doug Rattmann has been proud to call Test Chamber Seventeen his home. And so, whether you are here to stay, or passing through on your way to the maintenance areas, Welcome to Test Chamber Seventeen. There's more love here."

"Yeah. Just as the time I met Doctor Freeman. He said he had killed Breen. And he told me something about "our benefactors", here wonderfully replaced to "our employees". I think Cave has just proven himself to be GLaDOS. Really."

(garbled) And then He made a time machine… and travelled into the unknown… (garbled)

And then GLaDOS-ified voice came again.

Sarcasm sphere self-test complete. YOU'LL DIE!!! HA HA HA HA (garbled)

"This whole thing is just failing. Ugh. Almost there. The Turret Run. Better not do it here…"

As garbled mixes of Cave, Breen and GLaDOS continued, Chell made it into the elevator that leaded to Test Chamber Seventeen.

The Vital Apparatus Vent will deliver (boom) The 4th Millennium (boom) a mathematical error (boom) Aperture Science Handheld (KABOOM!!!)

The whole facility went down and turned black again (save for the faint light of the tinted glass rooms) as Wheatley was already in the Chamber Seventeen. This time he fell from the rails into the part just above the Aperture Science Wall Failure, still active. And the Companion Cube was delivered.

"That was my love… But it's no longer. I'll find that core. And I'll find Doug. I'm almost sure of it."

And that time, beneath the Aperture Science Wall Failure...

„Oh no... Why I had to incinerate my Companion Cube..."
