A.n. This is another one that I've been looking forward to and I'm very excited about it.

"So where are we going?' I asked after I had stumbled my way to the console room from the kitchen. The Doctor looked at me with a minorly manic look.

"I've no idea," he said and smashed the mallet on something.

"Why am I not surprised?" I teased as he placed my hand on a lever.

"Hold that down. The TARDIS just started flying herself after we got an emergency signal."

"So, did we receive an emergency signal or did the TARDIS equivalent of the check engine light come on?" The Doctor leaned around the console to give me a withering look. I shrugged slightly.

"Neither. More like when you get texts when you live in an area that's under a storm warning."

"So, she's warning us of bad weather" I asked with an eyebrow quirk.

"Well," he trailed off so I arched my eyebrow higher. "More like something occurring that could tear apart the fabric of space and time."

"And, of course, we're flying to this thing." I sighed before smiling. "You know I used to have a sense of self preservation." The Doctor came to a dead stop and looked at me. I grinned wider.

"It was very small," I admitted just as the TARDIS shuddered to a halt.

"Can I take my hand off this lever?" The Doctor nodded so I pulled my hand off as he wandered over and pressed his lips to my forehead.

"I will finish teaching you how to fly this thing," he promised, and I smiled softly.

"Maybe not while the potential for the universe to tear apart is still happening," I suggested and headed for the door.

"Allon-sy then?" he asked as he rested his hand on the door knob. I nodded and he threw the doors open.

"it kind of looks like a submarine," I said while tilting my neck to the side slightly.

"It also looks vaguely familiar." At the Doctor's words I studied it closer to look for historical similarities. As I looked at it, I got a strange twisting feeling in my gut, as if all my internal organs had been scrambled.

"Emma," the Doctor said sharply with concern. I tore my gaze away and blinked at him. The twisting feeling decreased immediately as he reached up and caught the blood that had started to trickle out of my nose with a few rhythmic strokes of his thumb.

"I was looking at the ship and I felt wrong. Like nothing was where it was supposed to be," I explained while keeping my gaze glued to him. He paled slightly.

"Looking at you makes it stop," I said before I could think better of it and blushed immediately.

"You could-. "

"I will not stay in the TARDIS," I protested before he could finish.

I still hadn't told him about the message from the other universe, about how I had died in that other world because I had stayed in the TARDIS. Somehow telling him didn't seem like a good idea.

"You could at least let me finish," he replied dryly. I shook my head.

"Never." I gave him an innocent smile. "So why didn't the TARDIS park us on the ship?"

"She was going to, but I wanted to see what it was first. That's why you were holding down the lever. Bit of a manual override."

"I thought it was so I'd stay out of the way," I said as we stepped back towards the console and the Doctor actually looked hurt.

"Never," he stated fiercely. The TARDIS gave me a mental shoulder shove as if to say, 'You think I'd let him do that!?'. I grinned as the TARDIS started up again.

"So, what was vaguely familiar about it?" I asked.

"It looked like-." He paused. "But it couldn't- "He cut himself off again and stared forward like he was trying to figure something out.

"Do you think I'll be able to make you finish a thought before I'm done traveling with you?" I asked teasingly. He laughed and entwined his hand with mine.

"Well you do have forever," he said softly with a hand squeeze. I squeezed back as we landed again.

"Split up to cover more ground?" I suggested as we reopened the doors and stepped outside.

"No. Not if there's the chance you could develop that feeling again." I reached into my pocket, dug out my phone and wiggled it between my fingers.

"I promise to call if the weird feeling comes back." He still looked skeptical. "Come on, the fate of the universe is at stake. The faster we fix it the better, right?"

"The instant you feel weird you call. Not a few minutes later, the instant." He still looked a little put out by what he was offering, but clearly my logic had won him over.

"Deal," I agreed bouncing up on my toes to kiss his cheek. "I'll call in twenty minutes to check in as well okay?"

I wandered around the submarine aimlessly until I turned a corner and slammed into a blonde girl.

"I'm so sorry. I didn't know there was anyone else here!" I cried as I scrambled up from the floor to help her before I froze in place.

"It's alright. I didn't know anyone else was here either," Rose announced as she took my still outstretched hand. My stomach swooped weirdly when she did, enough that if not for the fact that she dropped my hand and the feeling went away instantly I would have called the Doctor.

"You're Rose Tyler, aren't you?" Rose took a step back and her face hardened into defensiveness.

"How do you know who I am?" She asked cautiously. I understood her hesitancy because it was always a little alarming when someone knew who you were before you knew them.

"I'm Emma. I travel with the Doctor," I said and instead of relaxing like I expected she tensed up further.

"No, you don't. I travel with the Doctor. There's only one Doctor," she said a little bit mockingly and I bit my lip so that I wouldn't snap at her.

"I'm pretty sure you were there when the metacrisis happened," I said. "You got stuck in a parallel world when the Cybermen invaded Earth. You came back when the Dalek's had the Reality Bomb. You went back to the parallel world with Ten Two."

"So, does that mean I'm not in the parallel world anymore?" She asked as all the defensiveness eased out of her and I shrugged.

"I'm not really sure what's happening currently. I imagine we'll have to ask the Doctors," I said. "I'm guessing your Doctor is also wandering around to try and find something?'

"Yeah. Yours as well?"

"Against his better judgement. Do you have a way to communicate with Ten point Two?" I asked. Rose unclipped a walkie talkie from her belt and I nodded. "Okay I'm going to call my Doctor and see if we can pool our resources," I said as I fished out my phone and typed in the number. Rose snorted.

"Since when does the Doctor carry a phone?"

"Since I got shot," I answered before I realized how that sounded and winced. I gave her a sheepish smile at her baffled face. "Long story."

"What's wrong?" The Doctor asked instantly with a touch of panic in his voice as he picked up on the first ring.

"I think I figured out why the TARDIS freaked out," I said.

"Are you okay?" There was a lot more concern in his voice now, so I nodded even though I knew he couldn't see me.

"I am perfectly, one hundred and ten percent fine." I heard him release a huge gust of air in relief.

"Emma you scared the hell out of me." I winced again as I realized that I'd called about ten minutes into our agreed upon twenty.

"Sorry."

"What did you find?" I looked over at Rose and tried to decide how to explain it.

"I found Rose. Or well we found each other I guess," I said. Rose still looked very confused and judging by the noises the Doctor was making he was just as confused.

"Listen I don't know anymore than you do. Do you want to meet us somewhere, so we can figure it out?" I asked and looked at Rose pointedly who nodded and took a few steps away to radio Ten Two.

"I'm already on my way to you," the Doctor said, and I fingered my TARDIS key idly.

"Right we'll just stay here then. See you in a few." Rose wandered back over after I had put my phone back in my pocket. I gave her a friendly smile.

"Ten Two on the way?" I asked, and she gave me a curious look.

"Ten Two?"

"It's going to confuse me less. Tenth Doctor point Two. Ten Two," I explained with a shrug.

"Yeah he's coming. He tracked your cell phone signals," she said. I took the opportunity to study her before the Doctors showed up. I'd heard a lot about her, but somehow the Doctor always skimped on the details. She looked close to my age, though the math worked pretty perfectly on that, but also a little bit older somehow. Then I remembered that my estimate might be a little off because time moved a little faster in her parallel world just as the Doctors arrived at the same time through different doors. Ten stiffened slightly at the sight of Ten Two before his eyes landed on me and relief flooded his features.

"I told you I was okay," I said as he slid up next to me and grasped my elbow to gently turn me to face him so that he could see I was alright. I looked at Ten Two and gave him a wave. "I'm Emma by the way."

"How did you get here?" Ten Two asked and Ten frowned harshly.

"I was about to ask you the same question." I glanced between the two Doctors and then looked at Rose.

"This is trippy as hell." She laughed, and I stepped forward with my hands raised. "Doctors let's not fight. We're here to share information. Ten Two why don't you start?"

"Ten Two?" He repeated with a frown and pointed at himself. I nodded and pointed my finger at Ten.

"Ten." I moved to point my finger at Ten Two. "Ten Two." Ten laughed loudly and Rose shrugged.

"It will make it less confusing," she said. Ten Two shot her a look like she was betraying him before he started talking.

"It started yesterday when Torchwood picked up some readings that were very similar to the ones the dimension cannons put out when they were still in testing. We were monitoring them when they suddenly spiked and this submarine appeared in orbit over Earth. Rose and I volunteered to go check it out because it looked like something that we'd found blueprints of in the Cybus labs." Ten hit himself in the forehead.

"That's what seemed so familiar about it," he said self despairingly. "Do you have a copy of those readings?" Ten Two nodded and Ten bounded over while pulling out his glasses and they both bent over a few sheets of paper.

"Would you care to explain what a dimension cannon is while they're busy with readings?" I asked Rose and she looked at me in a little bit of surprise before she nodded.

"Yeah of course," she said and gave me a quick explanation on what a dimension cannon was and how they worked.

"And they haven't worked at all since the Reality Bomb happened?" I asked after she was done.

"Not in the slightest," she said with a guilty sideways glance towards Ten that made me think she had tried to come back at least twice. Hopefully Ten Two had swayed her away from that notion because Ten had sent her back to that world twice for a reason. Whether or not Rose realized it, Ten would never be able to live with the guilt if he dragged Rose away from her family. Though that couldn't quite explain why Ten was looking at her as little as possible so I made a mental note to talk to him about it later.

"We've mushed together," Ten said as he slid his glasses back in his pocket. I raised my eyebrow up at him.

"Mushed together?" He nodded and slid his fingers together and wiggled them around. "Yes, that visual cleared everything up thank you."
