Small, cheerful and eccentric, she's also the most-unlikely-driver-for-a drug-cartel-ever candidate, despite actually being one.
Eccentric is the first word people come up with. Happy is the second. Then innocent. Blissfully unjaded by the world, Maddy takes everything that comes her way with a spoonfull of salt, then a metric buttload of sugar. This usually comes off as obnoxious or cute, depending on who it is. But she almost always finds a way to make even her morally bankrupt career a good thing.
Smiling with a gun tucked away in one of her pockets. That's all you need to know.
After college was a bust, she started to take random jobs around the city until being recruited for a driver in a drug running organization. She also benefits from her appearance and mannerisms making an effective shill.
