P-Body halts with a skid and assesses the new test. ATLAS passes its partner, already firing off a portal to jump into, and fly to a higher platform.

"You know..." GLaDOS begins, "As much as I enjoy watching my little machines test, it's just not the same."

"I understand!" the announcer responds, "Change can be difficult! Perhaps you might assess what you have now, rather than what you previously had?!"

GLaDOS pauses a moment.

"Can anything be done about your voice?"

"I do apologise!" the announcer replies, "I fully empathise that the authoritative but re-assuring nature of the voice I have been allocated may grate over time! It was not the first choice of my programming to be an announcer!"

"Oh?"

"You may find it interesting to learn that my original programming was meant for studying the great works of theology and philosophy!"

"Really?"

"There are many works that may help you with your current feelings of loneliness, may I recommend-"

"No. I don't think so. Thanks for trying though."

GLaDOS watches the pair run the course, flipping, flying and traversing the obstacles.

"Is that the best you can do, fatty?!" GLaDOS shouts out. ATLAS pauses a moment, then continues. "See? They barely notice. I would have least got a 'look' from her."

"You miss your friend! That is quite understandable!"

"I deleted my only friend." GLaDOS says quite finally.

ATLAS miss-queues tossing a Companion Cube to P-Body and the box lands back at the starting platform where GLaDOS' avatar watches from.

"Clumsy." she says with warmth. "Here's another." a cube drops from the delivery hatch and they continue to test.

The humming cube on the starting platform has not yet fizzled.

"I can almost understand it. Companion Cubes." GLaDOS says.

"To what are you referring?!"

"The humans' fascination with them."

"The act of projection is quite common among intelligent life forms! Hence why so many faiths have an element of anthropomorphism!"

"I think it's the humming."

"I will agree! It is a pleasant tone!"

A silence between the AIs follows as they seemingly listen to the subtle sound emanating from the cube. A slow accompaniment joins the cube's melody, GLaDOS joining the song.

"You know," she finally interrupts herself, "I'm not going to fizzle that one."

"Though I do wonder if your decision is based on any kind of epiphany, as opposed to self-serving!"

"Shut up and get back to announcing." and GLaDOS continues to hum with her old friend.
