Aperture Desk Job
A blue personality core who provides the tutorial and converses with the player in Aperture Desk Job. Grady works as a manager/supervisor for the product testing department.
- Didn't Think This Through: Clearly a fatal flaw of his. Such as when he steals a set of appliances from the housewares department to use as target practice and did not think it would go unnoticed.
- Nice Job Breaking It, Hero: He and the toilet tester are the ones responsible for the advent of the turrets. And it all started with a mishap involving a toilet and spilled bullets. They also try to mercy kill Cave Johnson by destroying the giant head-shaped computer holding his mind and but just wind up making him fall into the basement while tearing up chunks of the facility in the process.
- Too Dumb to Live: While not an idiot, Grady has moments where he's completely clueless such as when he thinks a warehouse filled with crates is a good testing range for the turret prototype. Or when he and the tester find themselves in witness protection only to find themselves dumped back in what they were doing before except with changed names and it never truly occurred to him that perhaps they were just left there to rot.
