Luna the silver white wolf took the lead. She was walking on front while the other five wolves started to slowly surround him.
He knew their hunting pattern well enough and recognized that they wanted to overwhelm him with numbers.
He could feel Luna's emotions, she didn't seem to agree to this approach but Titan and Knight seemed to be more agitated, perhaps the instigator for this event.
Although, Luna was the leader of the pack there were a total of six wolves. Sage and Nova being other female wolves while Titan, Darius and Knight being the male wolves.
With Luna declining their approach they had to prove their strength in front of her eyes and what's better way to do it than to challenge the one person who could get close to her, Samuel.
Luna might be going along with it as a sign to show them that they had no chance against him. He had already subdued their whole pack when they first arrived here.
