The Doctor and Clara watched Mrs. Gillyflower open the door to reveal a perfect setup of a husband and wife sitting at their afternoon tea; a setup made of real people, immobilized and on display under a large glass dome. Men appeared behind the Doctor and Clara and women appeared from inside the house, approaching threateningly, as if possessed.

"Clara, spontaneous flying lesson . . . you can fly!" the Doctor whispered. He grabbed Clara under her arms and jumped into the air.

She was too heavy and he couldn't fly high enough in time. A man grabbed Clara's ankle. More men grabbed her and dragged her down. The Doctor struggled but they were too strong.

"Doctor!" Clara shouted.

"I'm not leaving you!" the Doctor growled.

The men caught him and pulled him down, struggling with all his might.

The Doctor leaned against the wall, his mouth wide open. Struggling was pointless. He could barely move, let alone pull the chains hard enough to break them. When there was nothing to do, there was always one thing to do. The Doctor pushed himself off the wall, struggling to balance with his stiff joints. He closed his eyes. He concentrated on the air around him. Stiff and stale air, just like him. It still worked, and so did his mind. The chains clanked as he slowly floated without moving his arms or hands, until his toes touched the floor lightly. Even his toes came off the ground.

The Doctor opened his eyes at a sound outside his cell. The door burst open and a man covered in dripping red poison, just like the Doctor, stumbled inside, screaming. If the man was frightened before, the sight of the Doctor floating in the middle of the room, his skin crimson red, his mouth hanging open, and some of his joints bent awkwardly must've terrified him. The Doctor, horrified, held out his hand to the man as he collapsed, terror finishing the poison's deadly job.

The Doctor floated for hours, nothing else to do. The chains seemed to feel lighter the longer he stayed. He slowly lifted his stiff arm and the chains wavered almost as if they were floating too. He maneuvered the chain into his hand. With a slow upward shake, the chain swung out and flopped back, almost weightless. His flight energy and control of the air was moving into the chains. He continued swinging the chains, learning the feel and trying to figure out how to take control of this new ability.

The Doctor suddenly stopped playing with the chains, noticing a faint rubbing on the door. A panel at the bottom of the door opened and a bowl of stew slid inside. The panel closed as the Doctor eyed the food suspiciously.

"You didn't think I'd forgotten you, dear monster? Hmm?" the young woman said who had rescued him from the refuse pile.

The Doctor dropped to the ground, starving, letting the chains fall with a loud crash.

The chains flew where the Doctor wanted them to go. He spun around the room in the air, flipping the chains without moving his hands and whipping them out as far as they could go before jerking to a stop. Days, weeks, he wasn't sure how long he'd been practicing, but it was long enough to get close to mastering this new side of flying. As long as the chains were in his hands, they moved how he wanted them to, until their connection to the floor stopped their momentum. As soon as he let go, they dropped like rocks.

He turned to face the wall, holding one chain with both hands. He pulled it tight and yanked on it. The air around each chain segment pulled on it. He felt the strain in the bolts in the floor. He couldn't pull harder. He wasn't strong enough yet. He jerked the chains in anger and threw them outward.

The Doctor spun around when he heard someone jiggling the handle of his cell door. His rescuer never touched the handle. It must've been someone new. He floated to the ground, letting the chains rest silently. He laid down by the sliding panel at the bottom. It opened and he shot his hand out, hoping to grab an arm. He let go and pulled his hand inside, fearing he'd grabbed a neck, as the person quickly backed off with a cry of surprise.

"All right, mate. You just stay calm now!" a female voice said after a short pause.

The Doctor held a chain and flung it against the door in response.

"I could open this door. Would you like that?" the voice asked.

The Doctor rattled the chains more softly, realizing violent and frantic banging might scare her away.

"Thought you might. But you and me has got to come to an arrangement, savvy?"

The Doctor sent the chains against the door again.

"Now, you stand well back. Do you hear me? I don't mean to harm ya'. But you try anything funny and I'll leave you here to rot. Is that understood?"

The Doctor knocked the door twice and decided to stay on the ground after witnessing the other man's reaction to him.

"Right."

The door slowly opened and the Doctor was delighted to see Jenny.

"Doctor?"

He reached toward her with a groan and lunged awkwardly, not used to being on the ground with his stiffened joints.

"What's happened to you?"

The Doctor grunted in response and glanced at his regular clothes on the floor.

"Can't you speak?"

The Doctor groaned. Jenny cautiously reached up and tapped his red face. It sounded like wood.

"Right. We're getting out of here," she said as she began to pick the locks on his shackles.

The metal finally came off his wrists. He was finally free. He floated and let Jenny pull him out of the room and down the spiral staircase. Without the use of his limbs it was difficult to do more than float and drift. They snuck through the building and down halls. They passed an elevator on its way up.

"Come on!" Jenny whispered, walking faster.

The Doctor pushed forward, helping Jenny pull him a little faster. The blind lady who had rescued the Doctor stepped out of the elevator, tapping with her cane. The Doctor held his breath and Jenny continued walking. Hearing two people breathing but one pair of footsteps would make the girl suspicious. The woman walked the opposite direction. Jenny pushed the door open at the end of the hall and pulled the Doctor through. The Doctor allowed himself to breathe again as they walked down the next hall, bathed in red light.

Jenny stopped and looked through the window to the vat room. The Doctor looked over her head and they watched as a rack holding six people was lowered into a vat of bubbling red poison. Jenny looked at the Doctor with an exclamation of horror. The Doctor remembered vividly when it had happened to him. They had to stop the horrible things Mrs. Gillyflower and Mr. Sweet were doing. The Doctor struggled to raise his arm and pointed down the hall, pulling Jenny's arm. She turned away from the window and followed him.

The Doctor lowered his feet to the ground in front of the antidote booths and reached for the handle with stiff and unusable hands. He groaned, frustrated that he couldn't open it.

"What is it? You want to go in there?" Jenny asked.

The Doctor groaned loudly in frustration. Jenny opened the door and helped him as he stumbled into the booth. She gave him his clothes and he grimaced at the pain of moving his arms to hold them. He managed to pull the sonic screwdriver out of his coat pocket and looked at it happily. He buzzed it at the controls inside the booth as Jenny closed the door on him.

A green light bathed him, rejuvenating his body. His joints unlocked and his skin softened. He closed his mouth for the first time in days and his red skin faded to pink and back to a healthy pale peach color. He changed out of his lab rat clothes and into his normal clothes.

The Doctor jumped out of the booth, good as new. "Ah! Missed me?"

"Doctor!" Jenny said in excitement.

"Jenny! Jenny, Jenny, Jenny!" He ran away and jumped into the air and flew madly back and forth down the hall, flipping and spinning. After using only his mind to fly for so long, using his arms and hands felt like super boosters. "Just when you think your favourite lock-picking Victorian chambermaid will never turn up!" He flew toward her ran into her, dragging her feet backwards, and kissed her. "Jenny!" he said when he finished.

As soon as she recovered her footing she slapped him. He fell against the wall as his feet landed hard on the ground. He rubbed his jaw. "You've no idea how good that feels! Right! Mrs. Gillyflower! We've got to stop her!" He walked toward the door. "And then there's Clara. Poor Clara. Where's Clara?"

"Clara? Doctor, wait!" Jenny said.

"Can't. Clara. Got to find." With a wave of his arms the Doctor was shooting toward the door.

"What happened to you? How long have you been like that?" Jenny asked.

With another wave of his arms, the Doctor flew back to Jenny. His feet touched the ground and he slid to a stop in front of her. "Days. Weeks. Don't know. Long story."

The Doctor and Jenny walked through the Sweetville courtyard at night, searching for Clara.

"Are we talking about the same person?" Jenny asked, "About that Clara?"

The Doctor flew to the nearest house and peeked inside the door.

"Doctor!" Jenny called.

The Doctor flew to her and laid an arm around her shoulders. "Couldn't see much from where I was, but I think she survived the process. She must be here somewhere." He flew to another house and checked inside.

"But Clara died. The Ice Lady . . . . Doctor?"

The Doctor flew back. "Well . . . it's . . . er . . . . It's complicated." He flew away again.

The Doctor scanned the antidote booth with the sonic screwdriver. "Okay, I think she's about done. I know who you think she is, but she isn't," he said to Vastra and Jenny as he opened the door, "She can't be."

"I was right, then. You and Clara have unfinished business," Vastra said.

Clara fell out of the booth into the Doctor's arms.

"Hello, stranger," the Doctor said.

"Doctor?" Clara said weakly. She reached up and tapped his nose.

"Uh-huh," the Doctor said. Holding Clara's arms, he floated her into the air just like his chains and set her gently on the ground.

"Whoa! What was that?" Clara exclaimed, "I felt sort of . . . anti-grav."

"Ah! Yes, that was me! I learned a new trick," the Doctor said excitedly. He floated into the air and pulled Clara after him.

She didn't feel heavy anymore. She waved her legs, looking at the ground, excited, but nervous. The Doctor turned and flew, pulling Clara with him, but she was pulling back, slowing him down.

He grunted. "Stop dragging!"

"I'm not doing anything!"

The Doctor stopped and faced Clara, studying her. "People are very different than chains. People have a mind of their own. I guess I'll have to work on it, and you too."

"Sure, but let's get out of here first."

The Doctor flew them back to the ground in front of Vastra and Jenny.

Clara noticed them for the first time. "Hi." She whispered to the Doctor, "What's going on?"

"Haven't you heard, love? There's trouble at t'mill!" the Doctor said in a Northern accent. "She's a lizard," he said in his normal voice.

"No, Clara. If we follow straight after her, she'll shoot Ada on the spot," the Doctor said.

"She wouldn't!" Clara exclaimed.

"She would!" The Doctor grabbed the chair out of the smashed control panel, lifted it over his head, and spun to face Clara. "Chairs are useful!"

Clara smiled.

The Doctor charged the window and thrust the chair through the glass. He climbed through the window and floated outside. He looked inside and Clara came to the window. He took her hand as she climbed into the window. "All you have to do is believe you can fly. Imagine you're weightless. Imagine the air is holding you. And then it will."

Clara took a deep breath.

"I will hold you, but I can't go fast unless you help me. Are you ready?"

Clara nodded. The Doctor floated her off the windowsill and pulled her beside him. He turned and flew away, but Clara was holding him back. He felt her struggling to stay calm. When she realized she was safe she felt lighter. The Doctor flew faster toward the factory. Clara slowly dragged less and less. The Doctor looked back at Clara and she was smiling. The Doctor smiled and flew rapidly toward the factory.

"Don't worry, Clara, I've smashed through glass before!" the Doctor said as the building approached.

"You've . . . . Wait, what?!"

"It wasn't a window . . . . And I wasn't carrying a passenger . . . . And I was falling."

"Doctor!"

The Doctor sped up and zoomed straight toward a window. He raised his fist and punched the window, smashing cleanly through. He swerved inside the building and spiraled up the staircase, propelled by his momentum. He flapped his arms and couldn't keep it up any longer while carrying Clara. He skidded to a stop on a landing and they continued running up the stairs after Mrs. Gillyflower.

"Now, Mr. Sweet, now the whole world will taste your lethal kiss!" Mrs. Gillyflower finished.

"I don't think so, Mrs. Gillyflower," the Doctor said. He snapped his fingers and pointed.

Vastra and Jenny took their cue and appeared on the landing above, veils over their faces and holding the flask of venom that was supposed to be in the rocket. They pulled back their veils.

"Very well, then. If I can't take the world with me, you will have to do," Mrs. Gillyflower said, "Die, you freaks! Die! Die!" She pointed the gun at Vastra and Jenny.

"Put down your weapon, human female!" Strax ordered from the opening of the chimney above, aiming his advanced weapon at Mrs. Gillyflower.

The mad woman shot at Strax, who fired back. The blast broke the railing Mrs. Gillyflower leaned on and she lost her balance and fell through the center of the spiral staircase. The Doctor leaped after her and caught her under her arms. She struggled for a moment before letting him lower her gently to the ground. Clara, Jenny, and Vastra followed them to the first landing on the staircase.

Mrs. Gillyflower stepped away from the Doctor, her head hung. "Why did you save me?"

The Doctor knew what she was up to and gripped some rope in his pockets. "Everybody deserves a second chance."

"Thank you sir. I promise you'll regret it." She spun around as she spoke, holding the gun.

The Doctor flipped his ropes out, his feet coming just off the ground. One wrapped around the barrel of the gun and it shot diagonally, and the other slipped down Mrs. Gillyflower's dress and wrapped around the poisonous leech. The Doctor jerked the ropes and the gun flew out of her hand, sliding on the floor, and Mr. Sweet found himself flying through the air. He fell to the ground and tried to crawl away, but the Doctor held him with the rope.

"No . . . . No!" Mrs. Gillyflower growled, realizing she was defeated.

Ada's cane tapped as she made her way down the steps to join her mother and the Doctor.

"Even a third chance," the Doctor said, "Look at the world around you, Mrs. Gillyflower. It isn't perfect. Nothing is perfect. It can never be perfect. Perfection is something you choose to see in imperfect things. All our imperfections make us who we are. When imperfect beings live together in harmony with each other and with an imperfect world . . . that is perfect." The Doctor held out his hand. "Choose to see the beauty in imperfect things. Choose to see the beauty in yourself. I know it's there. You can live in harmony with people and the world."

Mrs. Gillyflower just looked at his hand. "What are you going to do to me?"

"Nothing. You can go home. Take Ada with you. She can teach you. She's blind, but she sees the beauty in everything."

Ada walked toward her mother, her cane tapping the ground.

"Ada?"

"Mama?"

"Yes, child?"

Ada embraced her mother. Mrs. Gillyflower seemed uncertain how to react.

A gunshot rang out and Mrs. Gillyflower stumbled back.

"Ada! No!" the Doctor growled, seeing the gun in Ada's hand.

Mrs. Gillyflower collapsed. "Forgive me, my child. Forgive me," she mumbled.

"Never."

"That's . . . my . . . girl," Mrs. Gillyflower said with her dying breath.

The rocket exploded harmlessly in the sky.

"Well, Doctor, what will you do with that thing?" Jenny asked, meaning the red leech pulling at its leash.

"Take it back to the Jurassic era, maybe. Out of harm's way."

Ada came toward the Doctor. He grabbed her arm and yanked the gun out of her hand. He shook it angrily in front of her, giving her a face, knowing she couldn't see it. He turned away in frustration.

The Doctor jumped back when Ada began violently beating the leech with her cane. He couldn't look away from the gruesome sight as she smashed it to pieces. "On the other hand . . . ." the Doctor trailed off, stuttering.

Jenny chased the Doctor. "But, Doctor, that girl, Clara. You haven't explained."

The Doctor walked to her. He opened his mouth, trying to think of an explanation. "No. I haven't." He walked back to the TARDIS. "Ah! Look at the muck in here!" he exclaimed, running a finger along the TARDIS, "Right!" He stepped inside.

Clara stood in her 'I want answers' pose, her arms crossed, her head tilted slightly, and a rebellious smile ready to break the surface. The Doctor walked past her, pretending not to notice.

"Doctor, what was that with the ropes?"

"The ropes?" he said, still pretending to be oblivious.

"You pulled that gun out of her hand and the leech off her. How did you do that?"

The Doctor spun around with a smile. "Same way I made you fly. I can make things fly now." He pulled the rope out of his pocket and held one end. His feet floated off the ground and the rope began to float from the base to the tip. The Doctor bent it with his mind, creating waves in the rope. He swung it around and snapped it out. "I can make it do whatever I want." He flew toward Clara and snapped the rope out.

It wrapped around her wrist and gently jerked her arm. It let go and tapped her nose. His rocket boots blasted and he shot off the ground. He flew around the TARDIS, flipping and spinning and doing tricks with his rope. He formed it into a circle in front of himself and flew through it. He whipped it out, catching the railing on the balcony and flew straight up. The rope tightened and he flew over the railing and landed on his feet. Clara looked shocked, never having seen him fly like that before.

The Doctor hopped over the railing and glided down to her. "I learned to do it with chains on my wrists while I was Ada's monster. I had nothing else to do." He held the rope out straight. "When I let go . . . ." He let go and it fell to the floor. "I have to be touching it." He picked it up again. "But I have a feeling . . . there's more to be discovered."
