Graves was an insufferable, ignorant man. Yes he was handsome, and had a charming southern accent, but that didn't deflect his raging need for control.

Ever since you were tasked by Shepherd to work with the Shadow Company, Graves had constantly found a way to piss you off. He would talk about how successful his company was whenever you were in earshot, making sure to let you know he found your company pathetic.

Eventually you had enough, and decided to have a talk with him.
