"Silo?" the Doctor asked.
"Silo," Jack replied.
"Silo for me," Martha agreed, raising her hand.
The Doctor grabbed Padra under his arms and flew toward the silo. Martha and Jack ran after them. The Doctor flew toward a gate guarded by watchtowers and men with guns. He flew over the gate, but Padra struggled and the Doctor almost dropped him.
"Show them your teeth first!" Padra shouted.
Every single gun was pointed at the Doctor as he flew down on the other side. He landed, set Padra down, and raised his hands.
"Show them your teeth!" Padra shouted, baring his teeth.
The Doctor glanced back at Martha and Jack running up to the gate and bared his teeth. The guards left him alone and turned to the two new arrivals.
"Show me your teeth! Show me your teeth! Show me your teeth!" a guard shouted at Martha and Jack.
They looked at each other before baring their teeth in wide smiles.
"Human! Let 'em in! Let 'em in!"
The guards opened the gate and the Doctor ran to Martha and Jack as they ran inside.
The Doctor slid the door open, ready to step inside, and fell into the silo. "Whoa!" He let go of the door and fell headfirst with a grin.
"Doctor!" Jack shouted, reaching for him.
The Doctor flipped over and spread his arms. He sped around the rocket, dodging the many walkways connecting it to the living areas.
"Now that is what I call a rocket," Martha said, her voice echoing.
The Doctor flapped his arms and flew back up. He directed himself toward the doorway Martha and Jack stood in. He flew straight up against the wall, flapping his arms hard. He tried to step on the air, but his feet slipped. He struggled to keep from plummeting. His feet caught the air and he steadied himself for a moment before stepping up to the doorway. "They're not refugees, they're passengers," he said.
Jack grabbed his arm and helped him up.
"Thanks," the Doctor said.
"How did you cope without me?" Jack asked.
"I just flew," the Doctor pointed out, annoyed, "Can you do that?"
"I dunno, but can you? You were having a little trouble there."
The Doctor stepped aside and motioned toward the open doorway. "Then you step off the edge. C'mon. See how much trouble you have."
Martha grunted with impatience. "Boys!"
The Doctor and Jack gave each other a look before focusing on Martha.
"He said they were going to Utopia," she said.
The Doctor and Captain Jack raced through the silo. Jack ran ahead of the Doctor, grinning. The Doctor grinned and his feet lifted off the ground. He flew alongside Jack, his overcoat blowing behind him like a cape. He turned on his back and folded his hands behind his head. Jack glared at him. The Doctor grinned, flipped over, and flew ahead, leaving Jack in the dust, looking cheated.
"We'll see you in Utopia," Atillo said.
"Good luck," the Doctor said. He hung up the phone and blasted into the air. He flew as fast as he could through the difficult, tight corridors.
Martha and Jack tried to follow, but he was way too fast. A door was closing ahead. He zoomed faster, but it was too late. He slammed into the door and whipped out his sonic screwdriver, buzzing it frantically. Jack and Martha finally caught up. Jack messed with the keypad, trying to open the door.
"Get it open! Get it open!" the Doctor yelled.
Jack finally opened it and they ran in. The Doctor flew ahead.
The Futurekind blocked the way. The Doctor flew over their heads.
"Doctor!" Martha shouted.
The Doctor stopped and looked back. The Futurekind snarled up at him. He had to get to Yana, but he couldn't leave his friends. He flew back and Martha and Jack ran back the way they came. The Futurekind chased them. They ran through the corridors and the Doctor flew ahead, but not too far.
Jack stopped by a hallway. "This way!"
Martha and the Doctor switched directions and followed Jack down the hall. The Doctor slammed himself into the locked door to Yana's lab. Jack worked on the keypad.
The Doctor looked through the window. "Professor!" He pounded on the window. "Professor, let me in! Let me in! Jack, get the door open!"
