Everything at Aperture had a place. Walter the rabbit lived in a green grass paddock with nuclear waste to eat. Wheatley had a little storage bin a few floors up from the Aperture Science Relaxation Center's trailers that Test Subjects resided in when not testing, or being tested on their ability to sustain long periods of forced relaxation.

Really could have waited couldn't you?"

Wheatley sighed. He'd go and find Doctor Handy instead.
