Cody's weakened form came limping through the hoards of fighting wolves. Blood slicked his black coat flat against his body; his right ear had been torn right off, and countless slashes and cuts peppered his pelt, spilling rivulets of blood into his fur. His gray eyes were dull with the fresh wound that had been torn in his heart from learning that Willow had been a spy all along. But when he saw her, lying motionless on the other side of the clearing, his eyes flickered with fear. He felt his heart sinking like a stone in a lake, and everything else was blocked out. The battle seemed to disappear around him.
"Willow...?" he breathed. Despair seemed to yank him forwards, and he surged over to Willow's side. Tears sparked at the corners of his eyes, and he prodded her side frantically with his paws. "No... No no no, Willow, wake up..."
But he knew, deep down, that the wolf he had loved so dearly would never move again.
I never told you... that I loved you...
