The TARDIS landed with a familiar whirring sound. The Doctor held onto his homemade weapon tightly. He had to admit that he was a little nervous. There were so many things that could go wrong. He mentally shook himself. Now wasn't the time for doubting. He had to be strong.

Clara's fingers lightly traced the switch he had told her to press. She didn't look afraid at all. It worried the Doctor just how much faith she had in him sometimes. With as high of a pedestal as she had put him on, the only possibility was that he would fall hard.

He pushed those thoughts away quickly. He could worry later. Now, he had to focus. Sherlock and John were both holding bottles of vinegar, ready to attack in an emergency, although the Doctor wanted to avoid killing if at all possible. Both of them were calm, as if they weren't about to fight an eight-foot reptile armed only with vinegar.

The plan seemed simple enough. The Doctor needed to get close enough put the hook into her skin, or possibly around her neck or arm. Clara would flip the switch, sending a jolt of electricity through the wire and into the Raxacoricofallapatorian, effectively knocking her out. Clara would then shut the electricity off so they could drag her onto the TARDIS. From there, it would only take a minute to drop her off on her home planet.

The Doctor pushed open the door. He walked as silently as possible, approaching the old building. Even from outside, he could smell the rot and formaldehyde. The door had been left open carelessly. After checking to make sure Sherlock and John were with him, he entered cautiously.

There she sat in all her glory. She wasn't a Slitheen, the Doctor could instantly recognize. Even with her back turned to them, the differences were there. The grip on his hook tightened as he continued to step closer.

"Oh, I know you're there," the alien called out in a bored tone. "I can smell you, you know." She turned to face them. A bone chilling grin spread out across her face. Her eyes were large and black. The Doctor could feel the two men tensing beside him.

Without thinking, the Doctor ran at the alien. She was too stunned to move as the Doctor looped the hook around her neck. "Now Clara!" he shouted.

That's where it all went to Hell.

The alien lunged for the Doctor and grabbed onto his arm. His eyes widened in horror before the electricity hit him. His muscles spasmed as pain shot through every nerve. He tried to call for Clara, but his mouth wouldn't work. Somewhere in his mind, he was vaguely aware of himself falling.

Just as suddenly as it started, the pain stopped. His two hearts struggled to keep beating. The Doctor crawled backwards a few feet before collapsing. "Clara," he whispered softly as he blacked out.

XOXOXOXOXOXOXOX

"Clara, shut it off!" John shouted.

Sherlock's grip on the bottle tightened as he watched the scene before him. The Doctor crawled away from the Raxacoricofallapatorian, who in turn was staggering away from him. She grabbed the hook and threw it to the ground, snarling menacingly.

Clara was suddenly at his side, wielding a kitchen knife. "Doctor!" she cried out as she spotted him. She charged towards him recklessly, but the alien was too distracted to notice. "Oh, Doctor!" She knelt down beside him and placed her free hand on his face. "Please, wake up! We need you."

John had opened his bottle. "This counts as an emergency," he said before taking off towards the alien. As he moved to throw the bottle's contents on her, she regained her composure and knocked her arm into his. The bottle flew out of his arm and shattered on the ground, the vinegar inside spilling harmlessly onto the floor.

It took Sherlock a second to react. He opened his own bottle and rushed towards the Raxacoricofallapatorian. She grabbed John's arm and pulled him into her. "Take another step and I'll break his arm," she hissed.

Sherlock froze in horror. John groaned. "Sherlock, just kill her," he pleaded.

The alien's grip tightened. "Throw down the bottle," she demanded.

Sherlock complied without hesitating. The alien smiled smugly and placed another hand on John's shoulder. There was a sickening snap as she twisted his arm. "No," Sherlock screamed as John cried out in pain. It took all of his will not to rush forwards, but he couldn't risk it. The next thing the alien snapped could be his neck.

"Ooh, I like this one," she crooned. "I think I'll keep him."

John had stopped struggling against her grasp. The situation seemed hopeless. "John," Sherlock whispered. His voice shook with fear.

The alien began to back away slowly, her eyes focused on Sherlock. From the corner of his eye, he could see Clara moving with the knife in her hand. He focused on the Raxacoricofallapatorian and gave no sign that he could see her.

"Oh, sweetheart," she sighed. "This is pathetic. You really thought you humans could kill me? I'm Dadre Poss-Ann Treffory-Kile Amorian. I'm one of the most wanted Raxacoricofallapatorians in the universe. You don't stand a chance."

Clara was behind her now. She plunged the knife into her side. Dadre screeched and let go of John. Sherlock ran to him and grabbed his waist. He pulled him away from the alien as she turned to face Clara. Blood poured from the wound as she removed the knife. Dadre brought up her hand. Clara flinched slightly, but she held her ground. She raised the knife again, but before she could stab, Dadre shot a claw-like dart into her side. Clara's face paled as she fell to the ground.

Dadre turned again to face Sherlock. "Well, I would love to stay and continue this, but I really must be going. Don't bother following me. Your friends are in danger." She pressed her hand to her side in an attempt to stop the bleeding before running past him and out the door faster than what should be possible.

"Sherlock," Clara gasped. She had managed to crawl back over to the Doctor, who was still unconscious. "You have to help him," she pleaded. "His hearts are failing."

He let go of John and ran to her side. She was much too pale and weak for the size of her wound. "You've been poisoned. Don't try to move," he said as calmly as he could manage. He reached down and lifted the Doctor over his shoulder. "Don't move," he repeated. "I'll come back for you."

"Get him to the TARDIS," Clara panted. "I know what to do."

Sherlock nodded and turned to John. "Can you walk?" he asked.

"It's just my arm that's broken," he responded. His voice was weak. There was blood covering his arm, but Sherlock was too tired to identify where it was coming from.

"Come on, then. Into the TARDIS."

Sherlock managed to carry the heavy Doctor inside the blue box and lay him across some seats by the console. John sat down next to him. "Get Clara," he said weakly.

Sherlock nodded again and raced back into the abandoned building. Clara hadn't moved thankfully. She was still holding onto consciousness. Sherlock gently scooped her up and carried her to the waiting TARDIS.

"Take me to the console," she panted. Her eyes searched the buttons and knobs. "Other side," she said. Her voice was failing her. Sherlock brought her around the console. Finally, she seemed to find the button she was looking for. With weak fingers, she reached out and pressed it. "Emergency protocol," she explained before passing out.

The TARDIS door slammed shut as the ship whirred to life. Sherlock sat next to John, still holding the unconscious Clara as they were taken far away.
