Hello and again welcome to the Aperture Science Computer-Aided Enrichment Center. We hope your brief detention in the relaxation vault has been a pleasant one.

The Vital Apparatus Vent will deliver a Weighted Companion Cube in three, two, one.

This Weighted Companion Cube will accompany you through the test chamber. Please take care of it.

The symptoms most commonly produced by Enrichment Center testing are superstition, perceiving inanimate objects as alive, and hallucinations. The Enrichment Center reminds you that the weighted companion cube will never threaten to stab you and, in fact, cannot speak.

The Enrichment Center reminds you that the Weighted Companion Cube cannot speak. In the event that the Weighted Companion Cube does speak, the Enrichment Center urges you to disregard its advice.

Please place the Companion Cube on the 1500 megawatt Aperture Science Heavy Duty Super-colliding Super-button.

Perfect. Please move quickly to the chamber-lock, as the effects of prolonged exposure to the button are not part of this test.

The weighted companion cube certainly brought you good luck. However, it cannot accompany you for the rest of the test and must, unfortunately, be euthanized. Please escort your companion cube to the Aperture Science Emergency Intelligence Incinerator.

While it has been a faithful companion, your companion cube cannot accompany you through the rest of the test. If it could talk - and the Enrichment Center takes this opportunity to remind you that it cannot - it would tell you to go on without it because it would rather die in a fire than become a burden to you.

Although the euthanizing process is remarkably painful, 8 out of 10 Aperture Science engineers believe that the companion cube is most likely incapable of feeling much pain.

You euthanised your faithful companion cube more quickly than any test subject on record. Congratulations.
