Task: Question Answering
Input (English): Passage: The film takes place over a summer by the seaside and follows three girls through a summer that will change their lives. The story is told by Keira St. George, a girl who is trying to decide what to do with her life. She constantly throws away her college letter without reading it, but her father always retrieves it, annoying her more. Her two best friends are Glory Lorraine a beautiful but somewhat bitchy girl obsessed with marriage, and Lisa MacDougall, an awkward, born-again, religious girl who is obsessed with sex.
Glory babysits for Keith Clark and his wife, who works the night shift four times a week. Keith is a 32-year-old husband and father, who loves to ride his motorcycle, gamble with friends and smoke pot. One afternoon, Keira talks to Gordon Gruber, who is a bit slow, trying to get information from him about Keith, who has taken Gruber under his wing. Gruber tells Keira about the pot growing in Keith's backyard. That night, Keira and Lisa decide to take some of Keith's pot. While leaving, they hear what sounds like Keith and his wife having sex. Sex crazed Lisa decides to take a closer look. When Kiera joins her, the two discover that Keith isn't with his wife but with Glory! Later that night, Glory arrives at the bonfire. Keira and Lisa tell Glory about seeing her with Keith. Glory defends her actions, saying she loves Keith and he loves her.
The next day, while Keira works at the food stand, Glory tells her more about Keith and her relationship with him. Wheels begin to turn in Keira's head, and after debating with herself, she decides to go to Keith's. He thinks she wants to buy pot, but she tells him she will "babysit" too. She convinces him to let her in. He tells her he's married and she's half his age, but it is obvious both are attracted to each other. She leads Keith into the bedroom. 
Question: What is the full name of the character who convinces Keith to let her in?
Output (English): Keira St. George.
