I kind of spun the prompt "favorite" so that I can talk about my favorite character, Valerie, listing some of her favorite things.
Favorite
Valerie's favorite animal would have to be a dog. If she had to choose a specific breed, she'd probably have to say a German Shepherd, or maybe a Labrador Retriever. The breeds were known for being loyal, and were also the two most commonly used (so far as she knew) by the police force, which meant that they had to be good at sniffing out trouble. Maybe, when she moves out and gets a place of her own, she'll get a German or a Lab and train it to sniff out ghosts to help her with her ghost hunts.
Valerie's favorite thing to do in her spare time – other than ghost hunting, obviously – is martial arts. The activity kind of goes hand in hand with ghost hunting, but at the same time it's something completely different. It helps her to build her physical strength, sure, but it also allows her to build her mental and spiritual strength, too.
Valerie's favorite season is the spring, because it's a time of rebirth and growth.
Her favorite place to go to relax and hang out is the park in the middle of town, when there aren't ghosts attacking it, anyway.
Her favorite ice cream flavor is black raspberry, her favorite color is red, and her favorite pizza topping is just plain cheese. Her favorite subject is chemistry. Her favorite book is the entire Harry Potter series, but her favorite movie is Avengers. Her favorite music genre is pop-rock, but if prompted she'd have to admit that Fall Out Boy is her favorite band.
Valerie's favorite person is Danielle, because the girl showed her a different side of the story, the other viewpoint of her chosen lifestyle. Danielle also brought out a different side of Valerie, a protective side she thought she'd already discovered via her determination to protect the town, but it turns out that was something else entirely.
