Damon didn’t know how the fight started, or when he started loosing it. He was surrounded by 10 of Klaus’s hybrids, knowing there was nothing he could do to stop them. He prepared himself for their attack, but for his surprise it never came, the hybrids were beheaded one by one, untill the only person standing there was the one who kill hybrid the hybrids. Damon looks and sees me, Aurora Mikaelson, his enemy who had just slaughtered 10 of her brother Klaus hybrids to protect him, her enemy.
