Max - easily the worst person on the show!
After all the horrors that Vane and his crew did to her, some good came of it, she found friendship in Ann, Eleanor and Jack, leaving Eleanor aside both Jack and Ann were nothing but good to her, and she betrayed them in the worst way. She is the one responsible for coming up with the stupid plan of turning the gold in gems, but when the Spanish found out about it she took zero responsibility, first thing on her mind was to secure her place and whorehouse by joining Rogers and Eleanor, in the process throwing both Jack and Ann under the bus. She even had the nerve to go see Ann make her feel guilty about Jack's imprisonment.
Looking at the bigger picture, she shouldnt even have any share in the Urca gold since it was the pirates who captured it, yet she played the biggest part in its discovery. I hope Blackbeard skewers both Max and Eleanor in the final season, the black shall fly again in Nassau.
