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: The music video for "Déjà Vu" was filmed by British director Sophie Muller in New Orleans, Louisiana on June 21, 2006, with parts of the video shot at the Maple Leaf Bar and the Oak Alley Plantation in Carrollton, Louisiana and Vacherie, Louisiana respectively. The footage features couture-inspired outfits, vigorous footwork and sexually-themed routines. The video simultaneously premiered on July 12, 2006 on MTV's show Total Request Live (TRL), and Overdrive, MTV's broadband video channel. It reached the top spot on the TRL, Yahoo!, and MTV countdowns. The "Deja Vu" video topped the UK TV airplay chart in late July 2006.
The video begins with showing Beyoncé against a green wall and Jay-Z sitting on a chair inside a dark room. Beyoncé and Jay-Z then start to simultaneously play imaginary instruments, mimicking the song's tune. Scenes of Beyoncé are then shown in several different rooms wearing different outfits. As the chorus begins, she is shown running around and dancing out in a large sugarcane field. At the end of the chorus, she dances in a red dress in front of a pond and in a large red dress out in front of a mansion. When Jay-Z's verse begins, the two are shown alone inside a room, Beyoncé is now barefoot and bare-legged, she dances seductively around Jay-Z, and leads to the controversial oral sex scene. Beyoncé is then shown wearing a green skirt and bedazzled bra while dancing around in sand. As the song progresses, she is shown dancing alone in a dark forest wearing a sparkling black dress as fireflies circle around her head. The song ends with Beyoncé leaning back in a pose as fireflies race away.
What is the name of the person who is shown dancing alone in a dark forest wearing a sparkling black dress?
