Kairi has been sitting beside Donna's body for hours. Just sitting and watching. She hasn't eaten anything all day. I don't know what to do. There was no cure.
"Doctor." My name is a whisper
"Yes love?"
"Would it be possible to go back? Can we travel back to that moment and I can tell her not to touch it. I can wait until I have left the TARDIS to go find the stuff and I can talk to you and Jack and Donna. I won't be around myself so it won't cause a paradox. Please Doctor. She cannot die."
I can see how horrible she feels. I can feel how horrible she feels.
"Yes. I'll take you back but I have to stay in the TARDIS." Her eyes light up at my words. She has hope again.
"Thank you so much Doctor." She gives me a huge hug and we walk to the console room.
"Where is Jack?"
"I'm not sure I haven't seen him since he came to get me."
"Well don't let him leave the TARDIS when we land."
"Well of course." I set the coordinates. "You ready?"
"As ready as I'll ever be."
I pull the lever and the TARDIS moves to land in our past. Kairi walks to the doorway and creaks it open.
\(~0~)/
I peek out of the TARDIS door and I see myself run through the forest while the Doctor talked to Donna and Jack. "Hopefully the next time we see each other our ginger friend will be okay." I walk outside and run to the TARDIS.
"Donna do not touch what I found."
"Kairi didn't you just go into the forest?" The Doctor asked looking perplexed.
"Different Kairi. I just came to talk to Donna."
"Oh alright. Wait what?"
"Doctor there is no time for this."
"Sorry."
"Donna just through those trees I found some alien poison. You cannot touch it. If you do it will kill you and I don't want you to die. I need you alive. Please listen to me this one time and do not touch it." I hold her gaze and I see she understands.
"You're here because I died. You are trying to save me. "
"I am saving you. Do no touch it. Please." Donna pulls me into a hug. It feels nice having her here again. I lost her once I don't want to lose her again. Not like that.
"Alright I'll stay away from it."
"Kairi how did you get here?" The Doctor asked still confused.
"You brought me back."
"I did?"
"Yes you did. Thank you. Now go."
I hear my voice tell the Doctor I've found something. I walk back to the other TARDIS and wait for time to be re written.
…
We are all standing around a small pile of purple alien poison. I haven't decided what to do with it yet.
"Doctor we obviously can't leave it here if any other humans stumble upon it and get curious they will die. Don't you have anything in the TARDIS that will suck it up or something? " Kairi's face was full of worry.
"If we put water on it the ground will soak it in."
"So all we need is a bit of water?" Donna tilted her head in the direction on our right and there was a lake."
"Good thinking. Kairi will you and Jack go get a bucket for water?"
"Of course we will. Come on Jack." She took his hand and they walked back towards the TARDIS.
"So are you alright?" I ask Donna
"Yeah. I'm okay. I'm glad You and Kairi didn't just let me die."
"You know I didn't actually do it. I different me did it. One from the future. A me that no longer exists."
"But how is that possible?"
"Weeeell time isn't in a straight line. It's more like a big ball of Wibbly wobbly timey wimey stuff."
"So that means?"
"Time can be rewritten. When she came back to warn you and you didn't die that version of time no longer exists. She changed time to save you."
"You can do that?"
"Well most of the time. The only time we can't is if it a fixed point in time. Then no matter what we can't change it."
"Oh. I think I understand."
"It can be quite confusing sometimes."
"I can see why."
"Here comes Jack and Kairi."
"You know Doctor you could have told us all we had to do was ask the TARDIS for a bucket we were going around looking for one." Kairi handed the bucket to me.
"Actually I was wondering if Jack could fetch us a pale of water." I smiled at my clever joke but Kairi only half smiled and looked at Jack.
"Oh I'd love to Doc." Jack smirked and took back the bucket.
"I'll come with you Jack."
"Thanks Donna."
And off they went.
"Doctor?"
"Yes?"
"Do you know what kind of alien produced this stuff?"
"No. But I do know that it wasn't trying to attack. I think it was afraid."
"Yeah. There wasn't anyone around and it obviously isn't from Earth. It must be small based on the size of this little pile of poison."
" I agree."
It was a small pile barely the size of my hand. We need to hurry and find it. It's on a planet that it doesn't know well and it's afraid. Never a good connection.
"Here is your water Doctor." Jack handed me the bucket full of river water.
"Thanks Jack, Donna. You guys might want to stand back while I pour this." They all backed away and I poured the water onto the poison. The water splashed a bit but the ground did suck up the poison.
"There we go."
"Okay so now what Doc?" Jack asked assessing where the poison had just disappeared into the ground.
"We need to find it."
"We are going to find a small poisonous alien?" Donna looked confused.
"Yeah. Good point Jack you two actually have to stay in the TARDIS this time. The alien will kill Donna if it touches her."
"It will kill Jack too." Kairi pointed out and Donna nodded her head in agreement.
"Actually Rose made Jack immortal. He can never die he just sort of restarts."
"Yep. Good ol Rosie. I died and she brought me back to life. Now I can't die. Well I can but I just come back to life."
"Oh well this Rose woman sounds interesting." Kairi looked a bit confused at the thought of an immortal Jack.
"She was." I hate thinking about her. No matter what I tell myself I know we can never see each other again. Kairi kissed my cheek.
"What was that for?" I ask her
"For being you."
