Task: Question Answering
Input (English): Passage: Nisa is a native princess of a northern Brazilian tribe who comes to Los Angeles to stop an American corporation from destroying her rainforest home. With her is tribal shaman Joa, who uses black magic to get past the company guards and see the chairman of the corporation, resulting in his arrest.
Left to fend for herself in Los Angeles alone, Nisa, with the help of Carmen, finds work in a Beverly Hills mansion as the servant of an uptight couple whose son, Jason, lives only to dance. After spying on Nisa as she dances provocatively in her bedroom, Jason takes her out to a club. She is rejected by Jason's friends, and he is berated by his parents for dating the help.
Nisa runs away and gets a job at Xtasy, a sleazy dance joint/brothel, as a dance partner for male customers. Jason's friends visits the club and want to dance with Nisa, but Nisa refuses to dance with them. One of Jason's friends becomes sleazy towards her and she knees him in the groin. Later, the friends tell Ashley, Jason's girlfriend, and she runs back and tells Jason his little girlfriend is a sleaze working at Xtasy. He becomes morose, turns away from his buddies and girlfriend Ashley and goes to Xtasy to try to take Nisa out of the place. A bouncer beats up the would-be rescuer and prepares to deflower Nisa, but Joa walks in and magically stuns the attacker, which clears the place.
The shaman then heads back to the tribe, while Nisa and Jason, now in love, prepare for a dance contest, hoping to speak out about the plight of the rainforest when they are showcased on TV.
They win the contest, but the corporation's head stooge, Benjamin Maxwell, kidnaps Nisa afterwards. Jason finds them and helps Nisa to escape but twists his ankle, ruining their chances of performing on the show. 
Question: What is the name of the person that twists their ankle?
Output (English): Jason.
