~ Onward to the Past ~
Sherlock paced the room they were in, his mind racing a hundred miles per hour. "Right. I need you to bring me to yesterday, before Clara went missing. I wasn't there, so I can find her and tell her to go right back to you and stay there."
"I can't do that, Sherlock, it's risky. If she finds her way back to me, then all of this will never have happened. I could destroy an entire timeline, and then forget it even happened. We wouldn't be able to help anyone. "
"Ok, then, I can tell her to wait for us somewhere. That way you won't be destroying the timeline, only altering it. If I do this correctly, she could be waiting for us somewhere, right now."
The Doctor toyed with his sonic screwdriver. "Fine. Just make sure that I don't see you while in the past."
John held up his hands, "Wait a minute. Am I going too?"
The Doctor and Sherlock looked at one another as if silently communicating. Finally they said in unison, "No."
Sherlock eyed the Doctor and Clara from around a shop corner. They talked for a while, and then the Doctor handed her a map. Clara set off in the direction of the food stand. He went around another way, hoping to get there before her.
Sneaking up through an alleyway, he saw the stand and searched for the brunette. There was no one. "Perfect," he muttered, and put a grin on his face as he made his way to the man tending the food. "I'll make this quick," he told the alien, and punched him in his ruby colored face. Sherlock bound, gagged, and then dragged him into an empty store. Patting the alien's head, he smiled as he remembered wondering where the Avalonian who hadn't showed up for his shift had gone. He took the cap off the poor man's head, and whistled all the way back to the stand. Clara was there, poking around the odd fruits and vegetables. "I was wondering if I could get one of…" she paused as she took him in; a towering, dark haired human. "You're from Earth!" she smiled, handing him a purple apple.
"Yes." He took the apple, smelled it, and dropped it into a white paper bag.
"That's funny," she said, taking the bag, "I don't think I've ever met another human on an alien planet before."
"Listen, Clara. The Doctor sent me here."
She dropped the bag on the ground and stepped away. "How do you know my name? And how do you know the Doctor? I was just with him."
"Clara, it's very important that you listen to me. You can't go back the Doctor; you need to stay somewhere hidden for two days. Do you understand? It is very dangerous for you if you don't do exactly what I say."
"Where do I hide?" she whispered, moving aside for two Avalonians to view the fruit section.
"It doesn't matter, but at noon the day after tomorrow, you need to be standing here, at the food stand." He left her his scarf, and headed away from the food stand, into the alley.
The TARDIS appeared with a whooshing sound as usual. Stepping inside, Sherlock shivered, something he rarely did, and stood next to the Doctor at the console. "So… how is the fabric of time and space?"
"Still intact, since you and I and John are all here. The concept is a bit... wibbly-wobbly."
"It's mind boggling. Can you believe I've never really known that feeling until now?"
The Doctor smiled. "There's a first time for everything."
