Rose woke up screaming.
She sat bolt upright in bed, sobbing horrible, gut wrenching sobs. Her body shook, trembling with the force of her grief, her fear, her anger.
Ten was running. Running toward the sound of Rose, screaming. His Rose. Skidding around the last corner, he burst into her room.
"Rose!" He yelled, throwing open the door. She was shaking, her body wracked with sobs. In a flash, he was holding her in his arms, attempting to soothe her, forgetting about the regeneration.
She twisted out of his embrace. "Who the hell are you?" She yelled at him through her tears. "I don't know you! Where is the Doctor? Where is he?" She scrambled backwards, trying to get as far away from this, this man.
"I'm right here-"
"NO!" She cried out. "No, you're not, you can't be. My Doctor..." A choked sob escaped her lips. "No..." She whispered.
Her Doctor. Gone.
Rose collapsed, once again consumed with anguish. She no longer had the energy, the will to fight the man next to her, the one claiming to be her Doctor. She crumpled, no longer caring if his arms were around her or not. Her sobs started again, and she squeezed her eyes shut. Closing off herself. No longer letting herself feel the way his arms were tentatively wrapped around her. She trapped herself inside, trying to block out the nightmare she was living in.
She was so fragile in his arms, so small. She had closed herself off, the only movement being the tears that were flowing down her cheeks and the shuddering breaths she took. He pulled her closer, feeling a sharp pain pierce his chest every time she sobbed. What good was he? Not even capable of comforting the woman he loves, who, it turned out, loved him as well. He was the same, and different. He still loved her, but how could she love him back? He was a stranger to her. An imposter. This is what it feels like when the world comes crashing down. When the one you love doesn't know you, doesn't remember you. His own tears found their way down his cheeks and for the first time in all the 900 years of his life, he wished he could transform back. But there wasn't any chance that could happen now.
Rose slowly calmed down, her tears ceasing and her sobs turning into small hiccups. He was still there, the Doctor. Not her Doctor, but a Doctor nevertheless. She met his eyes, surprised to find them filled with an aching sadness. They studied each other for a while, neither breaking eye contact until he slowly laid her back down on the bed. "You should probably get back to, er, to sleep now."
She could feel it, her eyes slowly drifting shut, her body beginning to fall asleep.
"See you in the morning," she muttered, not quite conscious.
"That'll be fantastic." He murmured softly, and as he left, Rose's heart broke once more.
