Andrew is an engineer, twin, Pittsburgh native, and all-around good egg. He would probably be a good ally in a zombie apocalypse because he's very handy, but might not be able to shoot someone in the head if they were bitten.
According to Julie, his greatest talent is "diplomacy that would make even the greatest of Kennedys envious."
He is an ENFP-type personality who enjoys scuba diving, D&D, rock climbing, and outer space.
