"Daleks!" the Doctor growled. He stepped forward and walked into the air, arms spread. He stood between the Dalek and the people. "All right, so it's my turn! Then kill me! Kill me if it'll stop you attacking these people!"
"I will be the destroyer of our greatest enemy!" the Dalek exclaimed.
"Then do it! Do it! Just do it!" He beat on his chest with passion, sick of losing everything to the Daleks. "Do it!"
"Extermin-." It paused. "I do not understand. It is the Doctor!" It paused again, probably conversing with its master. "The urge to kill is too strong . . . . I . . . obey . . . ."
"What's going on?" the Doctor asked.
"You will follow," the Dalek ordered.
"No! You can't go!" Martha pleaded.
"I've got to go. The Daleks just changed their minds. Daleks never change their minds."
"But what about us?" Martha asked.
The Doctor looked back at the people of Hooverville before facing the Dalek again. "One condition! If I come with you, you spare the lives of everyone here! Do you hear me?" he ordered.
"The humans will be spared. Doctor . . . follow," the Dalek said.
"Then I'm coming with you," Martha said.
The Doctor floated down to her. "Martha, stay here. Do what you do best. People are hurt. You can help them. Let me go."
Martha looked at the Doctor as he watched the Daleks.
He stepped into the air to follow them, but paused and turned back. "Oh, and can I just say, thank you very much." He gripped her hand with both of his, pushing the psychic paper into her hand. He winked and jumped into the air and strode after the Daleks.
"That's not 'we'. That's just me," the Doctor said.
"I won't just stand here and watch you," Martha said.
"No, you're gonna have your hands full anyway. I'm sorry, Martha, but you've got to fight."
The Doctor jumped and flapped his arms and flew out the unfinished wall. He flew up the Empire State Building. He flew higher and higher. Wind and rain began to blast him and he couldn't fly straight up anymore. He spiraled around the building, pushing against the storm. He finally reached the base of the mast. He held on, panting, recovering from his hard flight. He buzzed his sonic screwdriver at the Dalekanium. The bolts were tight and it took a while, but he finally pulled the first panel off. He moved to the second and began buzzing.
His fingers were cold and stiff and the wind blew wildly. The sonic screwdriver slipped out of his hand and clattered off the edge. He jumped after it, but he would never find it in the wind and blinding rain. He swerved back up and climbed back up to the mast. He tried in vain to pull off the panels with his bare hands, yanking and clawing. He grunted with the effort and cried out to the sky.
"Is there another lift?" the Doctor asked.
"We came up in the service elevator," Martha answered.
"That'll do. You guys go," he said, running to the edge.
"What about you?" Martha asked.
The Doctor grinned. "I'll take my own way down." He spread his arms and fell backwards over the edge. He pinned his arms to his sides and dove like a bullet. The wind rushed around him. He fell and fell and fell. The skyscrapers finally began to draw close. He flipped over, spread his arms, and shot off through the sky. He barely had to work at all as he zoomed over the tops of the buildings. He curved back around and spiraled down the Empire State Building. He spiraled all the way to the ground and landed lightly on his feet. He waited for Martha, Tallulah, Frank, and Laszlo, a grin on his face and his hair an absolute mess.
"What do I need? Oh, I don't know. How about a great big genetic laboratory? Oh look, I've got one. Laszlo, just you hold on." The Doctor flew around, mixing solutions. "There's been too many deaths today. Way too many people have died. Brand new creatures and wise old men and age-old enemies. And I'm tellin' you, I'm tellin' you right now, I am not having one more death! Got that? Not one! Tallulah, out of the way." He flew down in front of Laszlo and put on a stethoscope. "The Doctor is in."
