The Third brother seemed to be on guard duty on the entrance of this underground passage as it seemed to have been just some kind of small grove before.
Outside though he had found out that their enemies were slowly closing down on them and their location, so he was extremely pissed off.
With the thought that the traitor was finally showing his neck, he returned back to the underground passage, and without considering the situation at all he attack the Second, while screaming,
"You vile piece of shit! How dare you betray our brotherhood and bring those damn Vampires here to deal with us!"
The attack had been too sudden, as the Second brother wasn't even able to understand what was going on when the claw of the Third brother hit him square on his head.
It was only a physical attack, but the strength behind that attack was extremely terrifying, as in actual fact even completely deformed the guy's head shape.
