Colonel Sebastian Moran isn't known to be sentimental. And he has only said the most sentimental sentence three times in his life time.
First, when he breathlessly held James in his arms after their first night together. It sort of just slipped out, and he couldn't stop it. Jim was curled close to the man, and just glanced up as he spoke. It was returned with an annoyed "Shut up." And the smaller form turning away from him.
The second time was when he stood on the altar, with a pair of smaller hands in his own. A proud smile had plastered on his lips, as he watched the man in front of him, whom had a confused, but still somewhat happy smile on his lips.
The words were whispered when he pushed the ring onto his finger. This time he did not reply at all. Instead he just turned to the priest as if though trying to ignore the colonel.
The third time, Sebastian held a smaller form in his arms. Jim's blood stained his hands and his clothes, but he couldn't care. Those large eyes which once had so much life was almost closed now, just about fighting to stay awake, to stay alive. He whispered it, despite that his voice were broken with sorrow. This time, a smile curled on the criminal's lips. One he had never seen before. "I love you too."
