A/N Sorry for the late update been a busy week but here you go. Enjoy :)

Disclaimer: I own nothing other than Ari :D

Ari felt her legs give out and if the man withnher Doctors face hadnt beempn holding her she would have fallen. Slowly he moved her to one of the seats scattered around the console her whole body shaking.

"Please you have to help me, I have to get back!" She pleaded as she allowed herself to be seated. "He can not be left alone! Please, please help."

"Hey, hey its okay." The other Doctor said holding her hands as he hunched down before her. "I promise you I will get you back." He then gave her a smile before jumping up and spinning around on his feet before turning back to her. "So what do we call you?"

"Ari."

"Ari…lovely name. Right Ari tell me exactly what happened before you found yourself here."

As Ari told him everything he reached inside his jacket pocket and pulled out an identical sonic screwdriver and scanned her before flicking his wrist and looking at the results.

When she finished her story he just looked at her a moment before spinning around and moving around the console hitting buttons and tuning dials.

"So, a bright light, correct?" He asked looking at her from the other side of the console.

"Correct." She answered.

"Did you see a crack?" He asked his eyes going to Amy a moment before finding hers again.

"No just a light."

"Okay. Amy hold this button here." Ari watched the red head join the other Doctor and doing what he asked before he came and knelt before her.

"Right, I need to see what happened. I need you to think about what happened and I need you to try and remember every single detail. Do you understand?" He asked as he put his hands to her face his fingers gently pushing against her temples.

"You mean like this?" She asked as her eyes closed and they where both suddenly stood side by side on her TARDIS watching as her and her Doctor talked.

"Yes, exactly like this." He turned to look at her and frowned slightly but said nothing. When he turned back to what she was showing she saw him look up and she couldn't help but smile as he took in the glass ceiling. "Nice." He commented before looking at the two people by the console.

She didn't know what he was thinking as he took in his other self but she got an idea when he spoke again.

"What happened to him?"

"You really don't want to know." She answered before she moved forward with her memory the two people before them moving around quickly before she stopped at the point when the Doctor was trying to get the TARDIS back under control and she was thrown about and then light she remembered seeing flooded the TARDIS.

"Wait stop!" The other Doctor said and she held the memory as he looked about then turned back to her. "Okay so I want you to try and peel back the light."

"How?" She asked frowning.

"Well your eyes see more than you think, it's your brain that filters them and makes you see only what you need to, but the information is still there, stored away. So what I need you to do is filter through that information and find out where that light is coming from."

"Okay, bare with me." She said then let her mind open up as much as she could letting it fully remember what she had seen. As she did this the image of what she was remembering started to change, the light slowly dimming and changing before he told her to stop.

"There, see it?" He said pointing up. As she looked to where he pointed she didn't know what to expect to see but what she did she was frightening. The glass ceiling had a massive crack running right across it.

"What is it?"

"A crack, a crack in space and time."

"And parallels." She said and he turned to look at her.

"You're good." He said smiling, but those words only sent her memory back to the cell and to the man with brown eyes, and because they where viewing her thoughts the image around them changed.

"No." She whispered before she pushed him out of her mind.

When she opened her eyes he was staring at her.

"What was that?" He asked but she didn't say anything and just held his eyes. "Fine. Right I know what happened. Kind of." He stood and ran back to Amy and told her to let go of the button she had been holding.

Ari watched them for a only a moment before she let her head fall into her hands as her resolve started to crumble away. Fresh tears stung her eyes and though she tried not to, all she could think about was her Doctor left alone. She needed to get back to him before his own mind destroyed him.

"Hey, its okay." A strong accented voice said and she looked up to see Amy as she gently put a hand on her shoulder. "He will help you."

"But it might be too late." Ari whispered.

"Why?"

"Because." She paused and looked at the other Doctor. He was looking at the screen before him but she knew he was listening. "I can't tell you."

"Why not?"

"Parallel universe's can sometimes have events happen at different times, but they still happen or can happen. What has happened to my Doctor hasn't happened to your Doctor."

"How can you tell?" Amy asked looking at her friend.

"His eyes."

"Right." The Doctors voice suddenly interrupted and they all walked over towards him. "So this is what I think happened. Ari you where going to Abrion-Graamia." He paused and she nodded. "Well we, by pure chance, where passing through that very sector only moments before you appeared. Which would mean that somewhere close to or even on Abrion-Graamia there is a crack that you some how were thrown through."

"Like the crack on my bedroom wall?" Amy asked.

"The very same. Now if we could find this crack then hopefully we can get you back to your TARDIS." He smiled then was about to turn back to the console when Ari asked a question.

"So if this crack wasn't on this TARDIS, how did I end up here?"

"Good question" He said turning and setting the coordinates to Abrion-Graamia.

"One you don't have an answer to."

"No, not yet anyway." He replied looking sheepishly at her.

Ari laughed slightly and shook her head. "You're just like him at times."

"Really? Umm well I guess that is only to be expected."

"How so?"

"Well we must both be brilliant." He stated with a smile as he also fixed his bow tie.

"Well yes I guess there is that."

"Also the big headiness." Amy chimed in as she winked at Ari. "They must have that in common?"

"Yes." Ari said laughing. "Yes they do."

"Hey…" The Doctor said still bent over his controls. "One of us is not here to defend himself and the other is busy, so…just Shh!" He said placing a finger over his lips and looking at the two of them which sent both of them into fits of laughter. At that moment they landed and both Ari and Amy stumbled.

"You so did that on purpose." Amy accused the Doctor.

"I have no idea what you are on about." He said with a smirk before running down the steps to the doors. "Right then, let's go and find us a crack."

.*.*.*.

The Doctor stood staring up at the crack in the glass ceiling as he fought back the over whelming urge to just give into the thoughts running though his head. She was gone his mind kept telling him, she was never coming back and no matter what he did he would never find her. But he grasped hold of the single good thought within as though it was a rock in the middle of a stormy sea. He would find her and he will get her back.

However, with every passing moment and with every negative result he received he slowly lost the will to carry on fighting.

The crack she had fallen through was unlike anything he had ever seen before and no matter what he did he couldn't get any sort of reading off of it. As he ran another test he just continued to stare up at it as he waited, but when the results finally appeared they yet again came up negative.

"But its there!" He said running his hand through his hair. "I'm looking right at it, so you must be able to pick up something from it!" He shouted at his ship.

Picking up his sonic for what must have been the hundredth time he took another reading and then inputted the data into the TARDIS mainframe. As the ship started to analyse the results he turned and sat on the stairs his head in his hands as he waited. However before the ship had finished he heard a voice shouting his name and instantly he was on his feet and look up once again. The voice shouted again and he knew it was Ari.

"Doctor!" She shouted her voice fearful. "Doctor, please!"

Fear shot through his hearts and he did the only thing he could think of and lifted his arm yet again and sent different signals towards the crack with his sonic until suddenly the crack split wider.
