The Doctor awoke slowly, his double heartbeat pounding in his ears. He attempted to move an arm to feel his head, but found his arms and the rest of his body constricted and stuck against a hard metal surface.

"Well," a voice rang out. "You finally joined us!"

He opened his eyes and looked around. He was in a metal prison, bound to the wall in a Zygon nest with Osgood, who was next to him, Kate, McGillop, and the Master. He stared at the blond Time Lord in shock. "Are you real?"

"No." He said sarcastically, glaring at him. "I'm the duplicate in the Zygon nest!"

The Doctor stared at him, the remark flying straight over his confused head. "There's a Zygon out there!"

"No kidding."

"Doctor, what happened?" Kate said, eyeing him seriously, trying to make sense of the situation.

He looked around. "I don't know. I upset Clara and-"

"You upset Clara?" The Master broke in. "What did you do?"

"Well, I was trying to tell them that the fake you was a Zygon, and I kind of burst in on the wedding rehearsal, and said some things that I deeply regret saying…"

"When's the wedding?"

He blinked. "Tomorrow."

"TOMORROW?" The Master strained at his bonds violently, glaring darkly at the Doctor. "Doctor, this is going to be the one time I ask you for help. Get us out of here!"

Kate was mildly startled. In the days that she had spent in this cell with this mad man known as the Master, he had never had such a dangerous glint in his eye. Whoever this girl was, he must really care about her.

"Maybe…" The Doctor looked around, searching for possibilities. "Have you tried everything you know of to get out of the nests?"

"Everything.' McGillop confirmed. "There's no way out."

"Can you get us out of here?" Osgood whimpered to his right. "This place scares me."

He looked over at her, giving her his most charming smile. "I will get us out of here. Don't worry about it." He looked down, and saw the tip of his sonic screwdriver poking up through the mess of pink substance. He pressed his chin against his chest, straining downward with his mouth open.

"What are you doing?" The Master growled.

"Trying to reach my sonic." He said, his voice coming out funny as he strained for the tip of the tool. "If I can reach it, I can reverse the molecules and set myself free."

"And us!" He reminded him, banging his head against the metal wall.

"Have faith in me!" He closed his teeth around the end.

"I am hesitant to."

He tugged on the screwdriver, jerking his head upward slightly. It was somewhat stuck amidst the bonds of the Zygon next. He jerked again, this time harder, his neck starting to hurt from being in such a cramped position for so long. This time, the tool flew out of the pink stuff, causing his head to jerk back violently and bang painfully against the metal surface he was bound to, nearly losing his grip on the screwdriver.

"Stupid." The Master hissed.

"I got it, I got it." He mumbled around it, attempting to press the button with his teeth. He was successful, and the familiar buzzing went off, accompanied by the green light.

Suddenly, the bonds fell away, and the Doctor fell to the floor with a resounding thud, his sonic skittering across the metal surface.

"Ha ha!" He cried, brushing strands of the Zygon nest from himself as he lay there. "That was far easier than I thought it would be!"

"Well don't just lay there!" The Master hissed. "Get us out!"

"Of course!" He grabbed his sonic and jumped to his feet, looking absolutely ridiculous with his burnt clothes and greasy hair, and of course, the goggles. He pointed his sonic at the Master's nest, and activated it.

The Master tried to stay on his feet as he was released, but failed miserably. His legs wobbled and gave way. He fell to the floor, his head spinning. He was weak from lack of food and water, and also from his numerous escape attempts, all of which had failed. He stared at the gray floor, panting heavily, his body adjusting to no longer being confined in one position.

"You all right?" The Doctor asked as he began to free the others.

"Yeah, yeah. I'm fine." He mumbled as he stood to his feet, clutching his blond hair. He stretched his stiff muscles, which were sore for being in one position for so long.

Once everyone was free, the Doctor addressed them. "Now, I can teleport all of you out of here using the teleportation device on my sonic-"

"Wait." The Master interrupted, remembering something.

The Doctor looked at him. "What?"

"You take them and get out. There's someone else in here that I have to free."

The Doctor gestured at the iron bars that lined the one side of their cell, which showed no indication of a door. "How are you going to get past these?"

"Easy." He walked up to the bars. "Like this!" Without thinking, he fired a blast of electricity at them. The bars blew apart, sending pieces of shrapnel and iron flying in every direction with a loud clattering that echoed around the corridors.

"Well, that's one way." Kate commented.

"Shh!" The Doctor hissed. "Do you want to get caught?"

"No, but do you have a better idea?"

"…No…"

"That's what I thought." He stepped through the hole he had blown, looking back at them. "Take them and go. I'll be fine till you get back. And, at all costs, stop the wedding." With those parting words, he vanished down the corridor.

Clara looked up from her spot on the couch as the TARDIS door opened. She had hoped that she would see the Doctor, but it was only the Master.

"The Doctor will not be attending the wedding." He said.

"Oh…" She sighed, trying not to sound too disappointed. She had hoped that the Doctor would forgive her for what she had said, but apparently this was not so. She supposed it was for the best. He did say that he didn't want them to get married.

"Oh, come now." He took a seat next to her, draping an arm about her shoulders. "It's his fault. This whole Zygon business has just got him so paranoid. Besides, he was getting in the way."

"I guess you're right." She sighed, remembering all the times he had barged in on her plans. "But he never meant any harm."

"You think so?"

"I know so." She snuggled closer to his shoulder. "It just won't be the same wedding without him."

The Master ran down the corridor, seeing another cell up ahead. Upon reaching it, he peered into the dark interior.

The sight made him seethe with anger.

The girl that they had met in the park hung trapped in a Zygon nest, her head hanging, obviously unconscious. The only way he could see that she was alive was the faint rise and fall of her chest, which was not considerable.

He gritted his teeth. She had been in there for days on end with no food or water. A five year-old wouldn't be able to stand such treatment!

Trying to be more discreet than last time (it was a wonder that no Zygons has come looking for him), he tugged on the bars hard, and they bent with the force he put into it. He stepped inside the cell and approached the girl.

Her blond hair was in bad condition, as was her flowery dress, which was visible somewhat through the pink substance. Her dress was tattered and her knees were bruised, as if she had been running from something, most likely the Zygons.

He tugged at the nest, and it fell away quite easily after a few moments of pulling. Apparently, she had been unable to escape the nest, even when the bonds were this loose.

He gathered her small body up in his arms, holding her close to his chest.

Her eyes flickered open at this movement, and her voice called out weakly. "Wha…"

"Shh." He silenced her. "You're safe now. I've got you."

She smiled dazedly at him. "You're that funny man from the park." With that, she drifted back into unconsciousness.

The Master looked at her for a moment before stepping out into the corridor. Now that he finally had the girl, he could get out of here.
