Don

Don is the leader of strongest (if not the only one) local gang in New Ark, and holds control over entirety of the Slums.

Lust Doll encounter Don for the first time when they get in conflict with the toll guy. Disrespecting Don's men means disrespecting Don, and Don wouldn't allow that. He demands much greater sum than pathetic $5 Lust Doll refused to pay — $200.

Being unable or unwilling to pay, Lust Doll asked how they may work up their bet — and accepted grunt work. Don wants certain runaway pet back, and Lust Doll may bring her for him.

Lust Doll tried to warn Cassie instead, but Don, not trusting them completely, sent his own men to follow their steps, and just abducted Cassie during night.

Taking Don out is not enough, because he has whole New Ark's police on his side — who would gladly start the hunt over someone who attacked their man. In return for protection and non-intervention, Don keeps Slums under total control, preventing any unrest. As long as that alliance stands, Don is invincible.

But not everyone is happy with that. Officer Arlene wants to strike down on Don for a long time (though perhaps for... more than one reason), and is willing to help — as long as Don breaks his part of the deal, willingly or not. For that end, Lust Doll bribed local homeless to start protests, spoiling Don's standings with police.

With the help of their new neighbour, Fawn, Lust Doll prepared plan of rescue operation, and, with additional information obtained from other locals, Sammy and Lin-Lin, started infiltration operation. With Don's lair's security being at its lowest, Lust Doll managed to reach Cassie and leave with her, thus allowing Arlene to step in and arrest Don.

Interrogation went... a bit unorthodoxly, but in the end conflict was settled down non-violent, with all sides being satisfied — especially Arlene.
