The Doctor leaned down and splashed some of the cool water into his face. It clung to his skin hungrily even after he wiped it off with the dirty towel. He turned off the faucet with a sigh and dropped the towel to the ground.

Straightening up, he looked forward at the man in front of him. His reflection stared back blankly. Dark circles surrounded his sunken in eyes, showing the tired ache he felt inside. He'd normally shake off the feeling and put on a happy smile, lying to himself and others that everything was fine. But now as he rubbed his eyes and gave himself a shake, his reflection merely copied him without a smile.

"C'mon," the Doctor sighed to the man in front of him. "You're supposed to smile now. You've got to be happy for Donna. You're supposed to happy."

"You're supposed to be happy," the image repeated dully.

A shudder passed through the Doctor and he gripped the sink in front of him turning his knuckles white. His reflection did the same, leaning forward till he was inches away from his own face.

"Stop it," the Doctor whispered.

"Stop it," the man in the mirror returned.

"You're not real," the Doctor kept his eyes locked with his reflection not daring to look away. "It's over now. You're gone, dead."

"You're gone…dead."

"No! I am me! You're not me! Can't you see?"

"Can't you see? You. Are. Me." His reflection shuddered and a hint of smile appeared. "Stop it."

"Stop it," the Doctor repeated as his eyes widened.

"Oh, look at that," his reflection sneered. "I'm ahead of you."

"No, no, no you're not here," the Doctor said as his voice shook.

"Did you really think… that I'd ever let you go?" His reflection smiled. "That you'd ever be free? You will never be free of me."

"No!" the Doctor cried. "This isn't real, you're just my reflection! When I close my eyes, you disappear!"

"I'm not just a face in the mirror. As long as you live, I'll still be here!"

"This isn't real, you're not real! This is just the end of my nightmare!"

"This is not a dream, dear Doctor," the man in the mirror laughed. "This 'dream' is the nightmare that will never end! I am here to stay no matter what you may lie to yourself. And I'll live long after you have gone."

"You'll never make it free from that burning prison within the diamonds!" the Doctor growled, his voice rising in his anger. "You're trapped and under my control!"

"You can't control me, I am you!" the devil in the mirror snarled back. "I live deep inside, each day you'll feel me eat at your soulless voice."

"It's over now!" the Doctor screamed.

"Not until you die, dear friend," the man murmured.

"If I die, then you'll die too."

"Not I, only you."

"No! I am the last of the Time Lords, the oncoming storm!" The Doctor reached up and placed his hands against the mirror. "I am the destroyer of worlds, the destroyer of you! I am—!"

"—the Doctor!" his reflection said in unison. "And yet you still lie that you're not me? We are the same, Doctor. I am you, you are me!"

"No!"

"You can't escape me!" the man in the mirror moved closer and pressed his forehead against the Doctor's. "I am the destroyer of worlds, the taker of voices. And soon I'll steal yours away and become whole once more!"

"NO!" the Doctor cried. Raising his fists together he struck the mirror, causing a cascade of glass to come raining down on the floor. The man in the mirror screamed with him in agony as his memory shattered.

Gasping the Doctor fell back and crumpled to the floor. His chest heaved as he gulped in heavy breaths. With his body trembling, he brought his hands up to his face and covered his eyes.

"It's gone," he whispered. "It's gone, it's gone, it's gone, it's gone, it's gone…"
