The Hel Academy base is covered with many formations.
It looked well protected, to say the least. It seems like they had the upper hand in the team competition. At the moment though, they didn't know what to do. They definitely saw Sam capturing three of their team members.
Those three were handling the offense for them and one of them is even considered a primary attacker.
The captain of the team is conflicted. They didn't know where Sam went, they only know the direction they spotted him. By now, he could have been anywhere. They also don't know the exact status of the three.
By now they knew that Sam managed to wipe out the people that attacked him at his base.
They believed this is going to be a payback rather than just him trying to deal a blow or two. It is much more than him trying to win the game. They became nervous.
The captain who had the responsibility of the team is even more.
He lost five people. All of them to Sam.
