Lilly:"Do you even remember us?"

Billy:"Our father trusted you."

Lilly/Billy:"But you went behind his back and killed us and Charlotte! His children!

Lilly/Billy:"Until you finally understand the pain you caused us and so many others!"

Lolbit:"I did it?"

Billy:"Is he finally dead?"

Lilly:"I'm happy. He's dead."

Billy:"We have gotten our revenge."
