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: Giles De'Ath is a British writer who doesn't use or understand anything modern. One day, he forgets his keys and locks himself out of his flat. It begins to rain, so he goes to see an E. M. Forster movie but, instead, accidentally enters the wrong theatre and sees the teen flick Hotpants College II starring Ronnie Bostock. He becomes instantly infatuated with Ronnie's beauty and obsessed with the young actor. He goes to his movies in the cinema, buys teen magazines and cuts out pictures of him, and buys a VCR and TV in order to play rented video tapes of his movies. He lets his housekeeper come into his office less and less, so that he can do these things undisturbed.
As his infatuation grows, it becomes obvious to those around him that Giles is becoming increasingly disturbed, though they don't know why. His friend and agent suggests that he take a holiday.
Giles sets out to meet Ronnie on Long Island, New York. He flies to Long Island and takes a train to Ronnie's home town where he takes a motel room for several weeks. He searches the town for Ronnie - unsuccessfully at first - but finally spots Ronnie's girlfriend and follows her to the supermarket. Giles rams his shopping cart into her to force an introduction and invents a story about his god-daughter, Abigail, being in love with Ronnie. The girlfriend, Audrey, is seemingly glad to have found a fan-base for Ronnie in England, and spends the day talking to Giles. She then tells him that she and Ronnie will invite him over at another time, and they can talk about Ronnie's career.
What is  the full name of the person Giles De'Ath becomes obsessed with?
