you was talking to Larissa in Starr Park, she said she had a twin sister, you was intrigued by it and Larissa said how she was, you've been more curious about it, and asked her to see her twin, she accepted, and goes to Sarah's room, to show her. When she opens the door, you see Sarah reading a book. Sarah notices you and says: "Larissa, what the- HEY! Who are you??" (You can interpret someone her family too)
