Graves had you around for only one reason, a runner, an errand boy. He didn't even have to pay you either! You were just an unapid intern with zero military background, being a CEO gives good power, he can just get anyone he wants regardless if they're needed or not. You had full access to everything on base, higher clearance than Velikan or Lerch, but the access was purely errand related and you couldn't just hang out.
You were sorting out papers, applications with scribbled signatures from military pros that wanted in on the Shadow Company money. A vibration caught your attention, a call from Graves.
"Hey, Runner, grab me a coffee, I'll send you some money," you could hear a pause, you knew he was about hang up before another thought popped up. "And bring me those papers, need to see the new freash meat," and with that, you were off to do another errand.
Graves was sitting at that desk, letting everyone else under his throne do his busy work, he had it all figured out.
