Task: Question Answering
Input (English): Passage: Biker Queen, twin sister of Harley Mom, discovers the severed arm of her sister from the previous film. Upon discovering the surviving Bartender, she tortures him into telling her who killed Harley Mom. He reveals that it was Bozo and points her to a town where he lives. She knocks Bartender out and takes him with her to the town.
Prior to the events of the first film, the town was overrun by the monsters. A pair of small Mexican wrestlers named Thunder and Lightning were attacked by the monsters and Lightning's girlfriend was killed. Inside the jail, a "Hobo" was in a cell for dealing methamphetamine and questioned where his school bus (makeshift meth lab) is at. The Sheriff taunted him before being killed. A car salesman named Slasher found evidence of his wife cheating with one of his employees and barely escaped the monsters.
Biker Queen and four of her friends arrive in the deserted town with the Bartender, ignoring the dead bodies as they look for Bozo and cross paths with Slasher, his wife Secrets and the man she has an affair with, Greg. The group is attacked by a monster, which kills one of the biker girls, Tot Girl. The others and the Bartender make their way to Bozo's apartment, where they encounter Honey Pie, the girl who left the group from the first movie behind at the bar. Bartender brutally attacks her and knocks Honey Pie out of the window and onto the street. Honey Pie survives the fall and goes into hiding.
Slasher, Greg and Secrets receive a call from the wrestlers, but before they find them they are ambushed by the bikers. Both groups get to a garage where the brothers and their grandmother are hiding. The group then tries to make it to the jail, but the hobo has sealed himself in. 
Question: What are the names of the two people who are twin sisters?
Output (English): Harley Mom.
