It's been a long time since Leo last hit the dungeon. Underworld's mission was so different than what he usually do.
It was noon when Chairman Daniel's men arrived at Leo's house. They were there to deliver the others license, for them to be allowed to go hunting.
Leo had a serious talk with them. He wanted to know more about each one of them. He first had a talk with the twins.
When they came to it, they were already inside the cave. The twins don't know who left them there. They grew up inside the cave, feeding on livestock. They never tried to leave the cave and live somewhere else, with humans nor think of doing it.
They said that they were having doubt at first, when Leo entered the cave. But, for some reasons, they felt that they have to and will follow that man.
They also said that, they were really happy, when Leo agreed to take them with him.
