"I'M FINE!" I argued back, trying to sit up.

4 hours River had been sitting at my bed side. I remember being in pain and crying, slumped against my bedroom door and then waking up in bed, River at my side.

"Sweetie your ill!"

"River." I sighed, laying back down, my tired eyes boring into her. "I know I'm dying."

"Hey, ignore what I said."

"But before that, I already said it to The Doctor, and I don't know why." She sighed at me. "What's the time?"

"Twenty past one."

I chuckled to myself. "Guess what?"

"What sweetie?" She smiled weakly at me.

"It's my 15th birthday."

"What? Why didn't you say!"

"Like you guys would care."

"Come on you!" She said, helping me out of bed, passing me some clothes. "I think on your birthday you deserve to do what you want. What do you want to do?"

"I thought I was too weak?"

"Do you want to spend your day all cooped up? Now what do you want to do?"

"I want to see Sadie and Charlie."

"Of course. DOCTORRRRRRRRRR!"

...

I stepped out of The TARDIS, refusing to let The Doctor, River, Amy or Rory come with me today.

"I'll be fine! I promise." I smiled to them. I was still weak but I was enjoying my birthday no matter what. "Go, I don't want to see a blue box for the rest of today!" I smiled, walking down the street to Sadie's house.

I knocked on the door, waiting patiently. The door flung open and before I had a chance to see who it was Sadie came flying into my arms, hugging me tightly.

"WHERE THE BLOODY HELL HAVE YOU BEEN?"

"Sorry." I smiled at her as she finally let me go, as we walked into her house, sitting on the sofa.

"You've been gone a week! Sarah's been round every day, she thinks were hiding you! She's been at Char's too."

Sarah was my careworker. She was nice enough but everytime something happened with the Daleks or Cybermen or at Christmas, she was insistant on us hiding underground.

"Here you go." She said, smiling, passing me a box. I slowly undone the red bow on top, opening it up. Inside was a gold key- oh fuck. It was the same one. The Goverhype key of life on a chain. "Do you like it?"

"Where did you find this?" I snapped.

"Er, er some market I went to with Mum last weekend, why does it matter?"

"Why this, of all the things you could get me? WHY THIS?"

"I just thought you'd like it, do you not like it?"

"No, it's great." I sighed, calming down and putting it round my neck and under my top. "Actually, it's just what I needed." Timestreams. I was guessing that when I visited myself in the past when the time came, I would have to bury this key for me to find again. I don't know why but there must have been a reason, and I wasn't gonna argue with the laws of time.

"HAPPY BIRTHDAAAAAAAY!" Charlie called, coming through into the living room.

"Hey you!" I jumped up, giving him a hug. "Ooh, I've missed you." I said, as we sat down.

"So come on tell." Sadie said, her and Char turning to me. "What's been going on? Where the hell have you been?"

I told them everything. About The Doctor and River, Amy and Rory, all the places we'd been to and then about the key, then talking to myself at Asgard, even the voices from The TARDIS. They wouldn't think I was mad, well maybe a bit, but these 2 would stand by my side no matter what. They listened to everything, and I bit my lip, scared to finish the end.

"...and well. I'm dying."

"WHAT?"

"I don't know if that's literally, or metaphorically but after that turn last night..."

"Your not dying!"

"I think I am..."

"Come home, you won't have to face all that."

"I can't leave! They need me, and I need them." I sighed. "I'm ill, dying. Like alien, timey wimey ill. I can't come back here yet, timestreams and all."

"Can't you tell them this? The voices, the key, Asgard? They could sort this all out."

"It's too dangerous, time lines have to be kept to, or the whole of reality could be in danger."

"What and staying with him isn't safer?"

"Please don't do this guys..." I sighed. "I'm really scared, and I don't even know what for yet..."

"Bet this turns out your parents were his long lost best friends from his planet or something..." Charlie muttered.

"Wouldn't be suprised Char, wouldn't be suprised."

...

"I can't believe your leaving already..." Sadie sighed, pulling out of a hug after a hug with Charlie.

"There's still things to do, and you know that."

The Doctor stood in the doorway of The TARDIS, a few metres behind us, smiling.

"Are you sure he's not-" Sadie asked, observing him.

"Yes Sadie, I'm pretty sure he is NOT a paedophile!" I said a bit too loudly, earning a frown from The Doctor. "I'll be back soon." I said, placing a hand on my chest, where the key was underneath before letting it flop down beside me again. "Bye guys." I smiled, walking into The TARDIS.

I headed up the ramp to the control room, River standing by the controls, Amy and Rory sitting on the stairs, all smiling at me.

"How was your birthday?"

"Great." I smiled. "I still don't feel so goo-" I came over all dizzy, starting to fall over, passing out, being caught by The Doctor.

"Mai?" I tried to answer, screaming in my head. "MAI!"

I blacked out.

'Your gonna find out very soon who you are, and he might hate you, but not for who you are, it's who you have to be.'

'TARDIS?'

'Yes it's me.'

'Why do I keep hearing echoes of conversations?'

'You just have to know these things.'

'I'm dying aren't I? But am I dying as a time traveller? Like I heard before?'

'Yes, as a time traveller. It seems so complicated now, but it will make sense later on.'

'I guess I have to steal you, to get to places on time, like meeting myself at Asgard.'

'No.'

'Then how do I? I'm conf-'

'Your waking up now, good luck you poor child.'

'NO TARDIS PLEASE!'

"MAI CALM DOWN!" I breathed deeply, over and over, quicker and quicker. I gulped hard and looked over to The Doctor next to me, River on the other. "Ssh. Are you ok sweetie?" River asked, stroking my hair as I layed back down.

"Knew it was a bad idea to send her out today." The Doctor muttered.

"What's wrong with me?"

"Were not quite sure..."

"Where's Amy and Rory?"

"They were here about 10 minutes ago, they thought best to leave you rest."

"And you two didn't?"

"We wanted to make sure you were ok." The Doctor smiled, getting up. "Just gotta make sure she isn't drifting off somewhere." He said, walking out of the door.

"River." I sat up quickly. "What's going on?"

"Like we said, were working on it."

"Not that." I snapped. "The voices, everything."

"What?"

"Don't give me that shit, you know something more is up, you can tell."

"I've been lying to him."

"About?"

"He thinks this version of me is the one he married 8 or something years ago, when actually I married him 16 years ago."
