Nathan, well that's how he introduced himself, made a run towards Oliver. He heard George's hurried voice, trying to guide his dear friend, not wishing him to get hurt.
Nathan sure was surprised of George's talent. Even though he is hanging upside down, who is still carried into air and got drugged, still got a clear state of memory and is smart enough to predict his moves. He thought, how good it would have been if they didn't meet in such situation. He really thought they would have recruited a skilled black pawn in their team with such great skills of George.
Tsk~ Nathan clicked his tongue in distress, and used a little more strength in his hands, Motioning his little sharp knife onto Oliver, aiming at Oliver's chest, " What a waste of talent little lamb, " He cussed as his knife swiftly went to hit it's aim.
