"Clara?" The Doctor woke up on the grass in front of the TARDIS.

"Clara? Tia?" He clumsily spun around on the spot trying to find them. No, only empty grass and the sunset greeted his eyes. There was no one there except for him. His hearts started thumping madly.

"No…" He placed his hands on his face in sorrow. He had lost them both. "No!" He yelled out in anguish as he kicked the TARDIS.

The phone started ringing.

"Hello?" The Doctor swiftly held the transceiver.

"Doctor!" There was a gasp. "You have to hurry." The voice seemed strained, like she had done a lot of running.

"Who is this?"

"It's Tia. I can't talk any longer. Clara's dying. Find us at space time coordinates 7:82-3492-35-9."

The phone hung up and the doctor stood there in bewilderment.

oOoOoOoOoOoOoOo

Somewhere dark, with occasional bumps and humming below her, Clara slowly opened her eyes.

"Hey, you okay?" A young girl came into her vision.

"I think so… Where are we?" Clara croaked. As her eyes adjusted to the darkness, she could see that they were in some sort of room with no doors or windows.

"I didn't really introduce myself to you before, sorry. My name is Tia, nice to meet you." She helped Clara up.

"I'm Clara, but I think you already know that"

Tia nodded. "Yeah."

"Anyway we're in a transporter ship. Judging by the material, I would say military grade." She said banging on the solid walls.

"Doctor?" Clara looked around, still in a state of daze. "Where's the Doctor?"

"Clara, calm down. He's safe, I've managed to send him away before they caught us. I was trying to teleport you too, but I didn't have enough time. Sorry." Tia apologised.

"That's okay. I'm sure he will come rescue us from whatever this place is."

"We're in a ship, probably flying through space right now. God knows where they're taking us." She slumped down in the corner. Clara sat next to her.

Clara noticed that Tia was eyeing on the silver bracelet. Her face was screaming guilt.

"It's a watch from the Doctor." Clara explained. Tia slowly brushed over the smooth silver, in sadness. Tia knew exactly what it was and saw how much damage the poison had done to her already even with the life support.

"It's a nice watch. Don't take it off, it suits you." She gave Clara a slight smile. Of course, she knew what would happen when the life support machine was taken away from her. She shook off the terrible thought and hoped that whoever were keeping them were reasonable enough to let her keep it on.

A door slid open and the bright light blinded both of them.

"The captain wants to see you." A soldier said gruffly.

As they were led out, he stopped and grabbed onto Clara's wrist.

"Hey! You leave her alone!" Tia growled. She quickly pushed him to the wall so that Clara couldn't hear anything. "We're still alive here because your captain wants us to be, correct?"

He gave a harsh stare.

"Don't go all quiet on me. This is a military ship. The military don't take prisoners and hostages in their ship unless they are tactically useful. I'm not stupid." She whispered.

He paused momentarily before answering. "Correct. The captain has demanded that you were kept alive."

"Well, you take that off her, and she won't be. Do you want to be responsible for that? Imagine what your captain would do to you if one of his precious assets was destroyed at the hands of one stupid soldier." She threatened.

"Her." The soldier corrected as he roughly pushed Tia away. "Keep walking." He commanded.

Tia quickly joined Clara's side. She breathed out in relief and looked at Clara with a reassuring stare.

'She's not going to die on my watch' Tia solemnly promised herself. She would take care of Clara, no matter what. After all, it was her wrongdoing that caused all of this trouble.

The door hissed open to the captain's quarters and they were forced to their knees.

"Doctor Tiana Gatford. Pleasure to finally meet you. I've heard a lot about you." A tall woman came out of the shadows.

"Why am I here? Why can't you just leave me alone? You destroyed my family, my life and my friends. What else do you want from me?" Tia tried to keep her voice calm and steady, but a slight tremble betrayed her

Clara looked at her in sudden realisation. She knew who they were. Judging by her tone of voice, she also already knew the answer to her questions. Clara wondered how much she actually knew about this incident. Had she already seen it in the future?

"As you might know, you are the only person known who will create the Polovox toxin. The fixed timeline states that you are the creator of the poison, but do not specify who you make it for. Well, that's going to be decided today." The one end of her lips twisted upwards.

"Over my dead body." She hissed. "I would rather die than create that monstrous poison, especially when I am forced by a madwoman like you."

"Sooner or later, you will create the Polovox toxin. I hope you make the right decision."

They were thrown back into the cell.

"You were really brave, I'm proud of you." Clara said, breaking the silence in the cell.

"Fear makes you brave." Tia said, smiling at the memory of her past. Clara had said it to her in one of the trips she had made to an alternate future.

"Indeed it does." Clara said weakly, followed by a cough.

"You alright?" Of course she wasn't, she was dying.

"Yeah, the cell is a bit cold. Maybe I'm coming down with the flu."

"Flu?" She chuckled. "We extinguished that virus millenniums ago!"

"Well, years ago is years to my future." She responded with another cough.

Tia knew that, but it still messed with her mind. If she were travelling this far into the future, she wouldn't have been able to cope with anything Clara was going through right now. Clara had told Tia in the future that she had done this for years now, with the Doctor and his blue box. Tia hated travel. She just wanted to live her life in a linear order, just like normal people.

Silence fell again, and hours passed. The cell became colder and colder, and they huddled to conserve heat. Tia started worrying as Clara became paler. The coughs were becoming more frequent and she was running a fever. The cold environment certainly didn't help her.

She couldn't stand to see her dying. She had to do something. Clara was leaning on her shoulder, sleeping with shaky, shallow breath. She placed her head gently down on the floor of the cell.

"I'm sorry, Clara." She approached the door and banged on it.

The little slit opened. "What do you want?"

"I demand to see the captain. I've changed my mind." She said, keeping an eye on Clara's pale form.
