The Doctor rubbed his forehead, as his hands drifted down lazily over his eyes. "Headaches again?" A voice behind him piped up. It was his new companion Lyra. She wasn't human like his other companions. No, Lyra was Swelastian...Well...Half human. Her mother was human, her father was Swelastian. She looked pretty human though. You know, besides the light blue hair, and purple eyes. There was only one problem. Her being Alien, there wasn't much of the stars he could show her that she didn't already know, so they were on earth most of the time.

The Doctor just nodded at her words, as they sounded kind of fuzzy in his head. "You know you should probably get that looked at. By a real Doctor, I mean" She pointed out, and he glared at her. She knew as well as he did, that Time Lords didn't normally get headaches.

"I'll be fine really." He promised, opening the door to her home planet. "I just need some rest."

She nodded as she was partway out the TARDIS door. "Alright, but before I go," She started. "Tell me what happened to your last companion." She asked with a serious look on her face.

The Doctor played with the end of his new jacket, and ran a hand through his new black hair. "Clara? Well...She couldn't quite handle regeneration." He said with a clinch in his tone, and just looked down. "Said she needed some time to think and take a break. When I came back, I didn't quite get the timing right...She...Became an old woman, and died of a heart attack. Died waiting for me."

Lyra felt it was a touchy subject, but needed to know a bit more. "Couldn't you just go back in time and get her?"

The Doctor shook his head. "It's a fixed time, she spent all those years without me, I can't change that."

Lyra nodded, looking down now also. "You should get your rest," She said after a long silence. "Get better Doc." She stepped out of the TARDIS, and said her goodbyes, watching the TARDIS fly away.

The Doctor sighed, thirteen lifetimes seemed too long sometimes. "Something wrong dear?" The voice came from a younger(er) woman, blonde, rather sassy, had her own gun.

The Doctor turned to his wife. "Headaches again." He said affirming her thoughts.

Stop. I (your reader) thought River was dead?
Yes...Well...Spoilers.

River walked up behind him rubbing his shoulders. "You know there's only one thing that could cause those, right?"

The Doctor nodded, letting another sigh escape his lips. "What do I do?" He said turning to look at her new facial features. To him, it was odd. Almost like seeing regeneration, yet not at all. River had died at the library, but he saved her to a hard drive system. All he had to do, was re-download her to to another compatible body. Which, he wasn't quite sure why it took him so long to figure out.

River looked him straight in the eye with almost a glare. "You know what you have to do."

"I can't! You know I can't!"

"You're just to much of a coward to go talk to her!"

"And what am I supposed to say? 'Hey Clara! I screwed up your life! Want to go on another adventure?"

"Sweetie, I barely think that regenerating and getting her long lost sister killed off is hardly something you should blame yourself."

"I don't blame myself! She blames me! And we all know it!"

There was a silence for a while before River piped up. "The paradox you created for her is causing the headaches. Paradoxes for Time Lords is like a sickness, it always ends up with side effects."

"River, please don't make me do this." He pleaded

"I'm not making you do anything." She pointed out. "Besides, I'm not the one getting the headaches." She sassed, and walked out of the room.

The TARDIS hummed, as the Doctor slummed down into one of the chairs in the console room, running his hand over his eyes again. The headache would go away eventually, but he would keep getting them until he fixed this. When was he going to fix this? How was he going to fix this? Clara would end up dying instead of her sister, and things would be much worse...for him. He knew he was being completely selfish about the situation, but he didn't want to lose Sam, Dean, and Sherlock too. There must be something he could do.
