There isn't a definitive answer to why Lilac, Carol, Milla, and Neera sleep under Hank's house as it depends on the specific story or universe they exist in. However, here are a few possible reasons: 1. Protection: Hank may have a secure and well-guarded house, offering the characters safety from potential threats while they sleep. 2. Camaraderie: The characters may have formed a tight-knit group or friendship and choose to sleep together under Hank's house to stay close and support each other. 3. Hank's hospitality: Hank may have offered his house as a place for them to stay, providing them with a comfortable and welcoming environment. These reasons are purely speculative, as each story may have its unique explanations for the characters' sleeping arrangements.
