“The accountant”
AKA “Suits,” and various other (sometimes less-flattering) nicknames from various other characters.
A tall, rather inscrutable individual, if she does say so herself. Which she would. Because what else is there to be, another face in the crowd? Most people are horrifically transparent—but that’s for another time.
What matters now is that there’s a challenge, and this individual is going to dissect it. Anything less isn’t worth the trouble; it amounts to nothing that matters. But to get to the core of a being? Then something’s working.
Most people don’t particularly trust the accountant, which is below her concern. Gary is an exception, bless his simple heart. He’s a good lad.
