Sergei continued walking towards the castle in the middle of the deepest forest because he was sure the werewolf he had been hunting for all along was there. He saw so many corpses of werewolves and bodyguards strewn on every road he took.
He retreated quickly because a werewolf suddenly attacked him. Sergei didn't notice the werewolf's presence and forced him to take a few steps back.
"Surprising isn't it?" someone asked Sergei.
"He is your prey, Ollien?" Sergei asked his sister back.
Ollien smiled and walked closer to Sergei, then started preparing to kill the werewolf. She didn't want Sergei to kill her prey, and she told her brother not to get in her way.
"He's yours and I just wanted to watch it," said Sergei, giving Ollien a chance to act.
Sergei also will not spend a lot of energy dealing with the werewolves he meets because he will face their leader.
