The Doctor
The Doctor looked back, making sure Lee was following behind. Reassured by the sight of Lee smiling back at him, he faced forward. Another smile shot through his memory, pulling him in. Rose. She ran to him, smiling her smile. She grabbed his hand, said she would never leave him. The look on her face as she was sucked into the void. The pain of loosing her. Never again would he make that mistake. Of loving one again, just to loose them. Of course, he had lost them before, but never had the pain been this great. He pulled himself from the painful memories, realizing he had come to a halt in the trees.
"D-d-d-doctor?" Lee stuttered, concerned. The Doctor shuddered a little.
"Oh. Sorry Lee." He said, and then began walking again. He hoped this plan would work. For Donna. For Lee. For him. He needed to know he left at least one of his companions happy. They found Donna's house with relative ease, and knocked on the door. Wilf answered, and his face broke into a large grin.
"Doctor!" Wilf said, and ushered them in the front room.
"Donna's in 'er room. She won't hear us." Wilf added.
"Well, Donna's the reason we're here. I need to see her." The Doctor said.
"But, but you said 'er head would explode if she remembered ya!" Wilf said, concerned.
"I know, just… I'm going to fix it." He said. "Oh, and this is Lee, Donna's husband."
A look of confusion crossed Wilf's features, and then he led them to Donna's room.
"Hello Donna!" The Doctor said, his features breaking into a smile as he remembered all they had done. Donna's head whipped around, and it looked like she was about to say something snappy, but she didn't. For once. Her features contorted with confusion, then slowly recognition. She smiled widely.
"Doctor!" she said, and then passed out. Lee caught her before she hit the floor, and then he and the doctor lifted her to the bed. The Doctor pulled up a stool, then gently pressed her temples. He closed his eyes, and stepped into her memories. He walked slowly through the halls of her mind, picking bits of the astronomical knowledge hidden in the corners and pockets. He came back to reality, and noticed that it was much darker outside. Lee was holding Donna's hand and caressing her hair.
"Y-y-you've b-been out f-f-for f-f-four hours." Lee said, slowly.
"Well, I'm done now. When she wakes up tomorrow, she'll remember everything, except the knowledge." He said wearily. "I'd better go. My song is about to end."
"Th-thank y-you D-doctor." He said, smiling sadly. The Doctor got up stiffly, and then walked away toward the comforting blue box. He still had a lot to do before he died.
