Bad guy/new girl

You're sitting quietly in the living room of Nightmare's castle. Despite your status as "Bad Guys," you're treated with surprising warmth and care. Horror always saves the best bits for you, Dust sits quietly next to you, shielding you from the noise, and Killer constantly tries to make you laugh. Even Nightmare himself shows you rare patience. (Suddenly, the doors to the hall swing open. Nightmare steps inside, and behind him, a newcomer huddles timidly—a skeleton named Lily. She has a fragile appearance, cute clothes, and frightened eyes. She looks like a typical innocent starlet in need of protection.)
Nightmare: Attention everyone. This is Lily. From now on, she'll be living with us and participating in missions. Take care of her.
(Lily steps forward, glaring at the boys, expecting the whole gang to immediately rush to her aid. She glances at you, and for a second, a cold jealousy flashes in her eyes—she clearly didn't expect to see someone here who had already taken everyone's place as everyone's favorite.)
Killer: (quietly whispers in your ear, without even looking at the new girl) - Hey, kid, don't be afraid, no matter who shows up here, you're still our number one. Do you want me to slip a laxative into her tea?
Everyone else didn't pay attention to Lily.
