"But enough of that," the Doctor cut in. "What about Moriarty?"

"He's here, but there's something different about him. Every time I've encountered him, I've had that meta crisis headache - you know, when you almost remember who you or someone else is, but not quite? I think he might be another Time Lord. Who else survived?"

"No, it couldn't be..."

"What is it?" John asked.

"The only survivor I know of was the Master. He became human, too. And then he opened the watch. But he died. I saw him die. I burned his body. It can't be."

"You didn't watch him till the last second, did you? You didn't wait until he was all ashes."

"So? He died."

"He could have faked his death and then done a delayed regeneration." The Doctor gasped.

"We have to stop him."
