- In the opening scene our main character wakes up to find that someone is in her room—it's her sister.
- She wants to show Regan her cool clothes, including a vintage flapper dress and a blonde wig.
- The sister tells Regan that she's going to dress like this to prom, and Regan starts to laugh and call her Lia… but she is quickly corrected. Her sister wants her to call her Luna.
- It turns out that Luna is technically Regan's brother, who comes in at night to dress up like a girl.
- An opening with a twist indeed.
