Given the task definition and input, reply with output. In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: In Spring 1989, sisters, Alex, and Annie Morrell, finish prep school and return home to start college. Their mother, publishing heiress Anne Scripps, welcomes them in her New York mansion. Anne has recently divorced her husband Tony, and is still struggling with the divorce. Nonetheless, she is happy with her new boyfriend, much younger Scott Douglas, a volatile-tempered young man whom she marries only months after their first meeting.
From the start, Alex is uncertain if she should trust Scott, having heard stories about a possible violent past. When Anne announces that she will be having a baby, Scott is distrustful to notice how Alex reacts with doubt about the news. To get rid of her, he claims that he has found marijuana in Alex's bedroom. Alex denies the accusation, but Anne defends her boyfriend, who forces Alex to leave the house.
Shortly after Anne and Scott's baby, Tori's, birth in June 1990, Scott gets violent and beats up Anne for inviting Tony's family for the baby's coming out party. Alex and Annie encourage their mom to leave Scott, but Anne forgives him after a couple of months. By June 1991, she and Scott are a happy couple again. On Alex's 21st birthday, Scott lashes out at Anne again when he finds her smoking in the same room as Tori, and then throws a guest, Stacey, off the stairs. Enraged, Alex dares Scott to hit her, and the police interrupts their fight, only to have Scott lie about the situation. A similar occurrence takes place at a formal ball, where Scott pushes around Anne in front of her friends. As they leave, the fight continues in the car, and Scott eventually throws her out while speeding.
Who does Scott Douglas throw out of the car?
