This fan spent a little bit of time making him or herself a companion.. cube.
Now, without further ado, I leave you with a few quotes from Portal’s GLaDOS.
GLaDOS: Area and state regulations do not allow the Companion Cube to remain here, alone and companionless.
GLaDOS: There was even going to be a party for you. A big party that all your friends were invited to. I invited your best friend, the Companion Cube. Of course, he couldn’t come because you murdered him. All your other friends couldn’t come, either, because you don’t have any other friends because of how unlikable you are. It says so right here in your personnel file: “Unlikable. Liked by no one. A bitter, unlikable loner, whose passing shall not be mourned. Shall NOT be mourned.” That’s exactly what it says. Very formal. Very official. It also says you were adopted, so that’s funny, too.
GLaDOS: 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.
GLaDOS: The Enrichment Center reminds you that the Weighted Companion Cube will never threaten to stab you and, in fact, cannot speak.
