Spoilers for the beginning of Portal 2.

I had one last view of the sky
Before She dragged me back down
Underground, and into storage.

There was Art in my room to view
And experience spiritual refreshment
As only an A.I. could dream up.

When at last he woke me up
That cheerful ball of chattiness,
Even the Art was in darkness

And so I go around again, on
Paths familiar and unfamiliar
But this time in company

Whatever lies ahead, behind or beneath
And however far we need to go,
The sky remains, above.
