Chapter 9: The Doctor's New Companion

Author's Note: The time has come! Test Chamber Seventeen is my new favorite chapter. Now, on with testing. Also, I do wish to apologize for such the long wait. As I saw my followers climb up, I knew I needed to finish this chapter.

The Doctor strolled into Test Chamber Seventeen with confidence. He had survived everything GLaDOS threw at him. His thinking was methodical and efficient. The Chambers were no match for the Doctor. He couldn't see much of this chamber, but there was a sign on the floor showing a person holding a cube with great affection. Above the sign was a cube, similar to the Weighted Storage Cubes from earlier, but had a pink heart on it instead of the traditional Aperture logo.

The Doctor ignored GLaDOS' explanation for the Companion Cube, grabbed it, and sprinted through the test chamber, avoiding laser beams along the way. He noticed something in the wall, an opening. He crawled through it, into a cramped storage room with horrible graffiti written on the wall, with obsessive messages like "The Cake Is A Lie" and "They Took The Cube Away". He looked at the Companion Cube. Of all of his companions, the Doctor hated it. The worst Companion ever, that is what the cube was. He was furious at his cube, until he locked his eyes on a door…

Meanwhile…

GLaDOS stared at the blue box. It was labeled Police Box. She thought of it strange. The Doctor walked out of it like it was a house, yet the box was tiny, only slightly larger than an average phone booth. An even bigger question rose to mind, "How did it get here?" GLaDOS swiveled wondering. It was ridiculous, not knowing everything. The box just materialized out of nowhere right in the middle of her chamber. HER PRIVATE CHAMBER! Only Blue and Orange were allowed here, and only with special permission. GLaDOS just stared at it, wondering its purpose and functions. The Doctor was in Seventeen now, it was time to kill the Doctor…

Back in the Chamber…

The Doctor sensed a low hissing coming from the chamber vents. He peered outside into the chamber itself and noticed a greenish yellow gas. It smelled of neurotoxin. The Doctor grabbed the Companion Cube, ran to the door, and unlocked it with the sonic screwdriver. He ran through, glancing behind to only see neurotoxin spread out behind him. GLaDOS was trying to kill him.

The Doctor realized that the whole story of Aperture was not in the chambers, but behind the scenes. Nothing but grey and blue painted the structures. He noticed white portal surfaces in various places. He leaped across to various points using the gun. The Companion Cube stayed by his side. He noticed that neurotoxin was spraying through the vents into the large room. It was definitely time to escape.

The Doctor spied a very peculiar door. It said GLaDOS on it. There was his goal; he needed to be there, because his bowtie, coat, suspenders, and other clothes were there. It also housed something even more important: the TARDIS.
