A/N: Hey guys, thanks you so much for reading my story. Also, I would greatly appreciate it if you could review. This is the first chapter out of a fic that I expect to end around 15 chapters, but in order for me to continue writing this fic, I'm going to need some encouragement and constructive criticism to keep me going. I will let you know that this story starts out with the 12 Doctor, if that isn't clear fairly quickly, then review and tell me so that I will fix it :) Happy reading!

"Clara? Clara?!" the Doctor ran through the streets of Barcelona searching for his young companion. He had just seen her round the next corner, her flowing red dress flapping in the slight breeze. The thought of the attention grabbing garment caused him to mumble to himself, earning a few strange glances from the surrounding natives.

"Clara, you know you shouldn't wander off, that's what gets us into trouble. You get captured by some vengeful alien bent on blood sacrifice and I end up saving the whole solar system because you won't leave after I break almost every bone in my body trying to rescue you!"

"Doctor!"

"Clara?" he yelled back as he shoved his way into the center of the developing crowd.

"Doctor…" Clara's voice betrayed her fear and confusion as did her strange predicament.

Clara was flickering. Almost like a hologram stuck at the end of a tape, not quite sure what to turn into. She stared at her hands and watched them go in and out of focus. When she spoke again, her voice was as garbled as her image.

"Doctor... why am... not here... you need to… something, she stopped and disappeared completely for a few moments, "Who… you? Wait… am I?" Then she was gone, leaving only her stunned Doctor.

"CLARA!" the Doctor screamed as he realized that she wasn't going to reappear. He began to pull his sonic screwdriver out of his pocket to scan, but realized that he didn't need to. He could feel the temporal energy radiating from the spot where Clara had stood and he could see the bystanders starting to disperse with confused expressions, as if they weren't really sure what had just occurred. Clara was gone. Someone had messed with history, and now she was gone.

The Doctor dropped his screwdriver back in his jacket and staggered away towards his TARDIS, feeling his loss, just like he had felt so many others. He had loved Clara like a daughter, they had been through so much together, but she never existed. How did this happen? H abruptly spun around to go back and scan the area, but fell to the ground and as his knees hit the marble walkway, he felt the tears force their way out of his eyes against his will.

At this point, the Police had been alerted to the man stumbling about and crying like a drunken idiot, muttering under his breath. From where he knelt in the road, he could see people pointing, so he began to rise from the street, but only made it a few steps before collapsing again on a bench to regain his composure. The policeman didn't seem to sense his grasp on reality and took him by the arm a little too roughly, not expecting his cooperation. The Doctor yanked it away, but lost his balance and fell off the walkway onto the street below at the exact moment, as chance would have it, that a cart came barreling down the street.

The impact threw him forward about 20 ft. and as he hit the ground he felt every bone not broken on impact, fracture and break, from what he could tell, he wasn't going to make it. He took an agonizing breath and considered for one selfish moment not regenerating. But he knew that wouldn't do any good. He could still save Clara!

He heard someone, probably a medic, ask him how he was and ask for a stretcher. The doctor laughed at the medic's optimistic inquiry then noticed the faint glow that started in his hand

"No need." He whispered when the stretcher arrived and allowed the regeneration energy to envelop him, knowing that when it was through, he would be a new man, with the same regrets.
