There was only one small problem with this arrangement. Chelldon was not an employee of Aperture Laboratories. He was, for all intents and purposes, property. So was Wheatley, but the droid had a much higher clearance level than the Test Subject, who was not actually suppose to interact and potentially contaminate other humans without strict clearance.

Just because Aperture was still recovering from an attack was not an excuse for Wheatley to be lax in his duties, but to be honest, he'd been lax in his duties from day one with Chelldon. He routinely broke his quarentine, brought him to the medic, let him fraternize with the chief of Aperture security, took him to the cafeteria--

Still, the experiment of Wheatley, the rogue AI, and Chelldon was actually fairly telling. And that was the only reason anyone let it continue.

"Oooh, and look there! See that core with the legs? I should get legs!"
