Why did Lux asked the boys to come in to the house?
One boy asked Lux where are her sisters, and she said they're coming.
And she asked the boys to come in to the house and the boys found out that they were dead.
Why? Did she not know that her sisters were dead? If so, why did she said that they're coming and she asked the boys to come in to the house? Is she trying to scare them? I really don't understand.
