Original Commentary
Robert isn't the only member of the IT department, but he is the only one there who Brisbane feels comfortable talking with. There's probably a junior employee who goes out to fix things in person and a manager who spends his time managing (up on the top floor). So Robert isn't the only person there but he works alone usually - Terrence

Modern Commentary
I stumbled across an unused script that featured Brisbane and Robert that's tangentially relevant. Basically the company had a carpool program and Brisbane needed Robert's help searching for other employees in his area that he could carpool with.
My notes were that they'd get a free car and gas allowance. I'm not sure if that means "access to a company car" or "the company just buys a car if you promise to carpool".
That seems unusually generous. It would have been reasonable if they gave you a couple bucks a month to carpool and hopefully I would have gone with that if I had written the story out fully. But my notes say "free car" so what are you gonna do?

Well, the good news is that he found someone to carpool with. We'll pick that up tomorrow. - Terrence
