The Cybermen threw the Doctor and I into a large nitrogen storage unit, where it was way below freezing and sealed us in.
"Are you alright", the Doctor asked me, and I nodded, "Not much for manners are they", he asked, and I chuckled as we rubbed our hands together.
Then we heard shuffling coming from behind, we turned around to see a female alien.
"Welcome", she said as she walked towards us; her skin was a combination of green, blue, and purple while her skin sparkled like crystals. She lifted her hand to wave and I saw that her hands were small with long fingers, along with long nails.
"Hello, I'm the Doctor and this is Acacia", the Doctor introduced, "My name is Flast", she replied in a mystical-whisper like voice.
"Is she a- ", "A Cryon, yes, but I'm confused. I thought the Cybermen had destroyed your race", the Doctor said.
"So, they did, but as you can see…some of us survived. Not many, but some…you both are looking very blue", Flast told us as the Doctor and I stood against to each other for warmth.
"Do you mean depressed or cold", the Doctor asked her as we made our way to the door, "Ah! I think I'll enjoy your company", she said amused.
"Not for long I hope, we won't last half an hour in here. It's freezing", the Doctor told Flast as we tried opening the sealed door.
"You both are in fact the first company I've had in sometime. I honestly thought without ever seeing another humanoid face. Let alone two", Flast said as she approached and then caressed our faces.
"Enjoy us while you can", the Doctor told her awkwardly, "We can't stay in here for too long", I added.
"Ah! Escape! They all talk about that for the first few minutes, then they become depressed", Flast told us, "I thought you said you haven't see another humanoid face", I said with narrowed brows as we backed away from her.
"Ah, so I did…I heard their voices, but never their face…until now", Flast told us as we stared at her unsure, "We don't have time for this, it's the locked door and the armed guard that's the unsolvable problem", Flast told us.
"Really", the Doctor asked, "Could have something to do with the lack of support on the part of their cellmate", the Doctor told her.
"I hate the Cybermen more than you could ever know and if I do anything to frustrate you or obstruct their course. I certainly would", she told us as she walked away to sit down.
"It seems your people have done quite a lot already", the Doctor told her as we made our way back to Flast.
She looked at the Doctor confused, "I assume you are responsible for the "stench of death" everywhere", the Doctor accused Flast.
"Doctor..." I said, but stopped as he looked at me confused, "I would be happier if the Cyber Controller and the others were al dead", Flast told us.
"So would I, especially now that they can time travel", the Doctor told her, "Oh, but they can't…not properly", she corrected.
"But they have a ship", I told her, "Which they stole, they do not fully understand the principle of time", she told me.
"Well, that's reassuring", the Doctor said, "I wouldn't get too excited", Flast told him, "I rarely do", he commented.
"Because what they have in mind will undoubtedly distress the two of you", she said, "What do they plan to do", I asked.
"They intend to change history", she said as she approached to place a hand on my shoulder "They can't, that's against the laws of time", the Doctor exclaimed.
"Then perhaps you should tell them that, because if you don't they intend to prevent Mondas from being destroyed and do that they plan to destroy Earth", she told us urgently.
The Doctor and I were getting colder by the minute as we were practically hugging each other, "Mondas? I think my blood is about to congeal", the Doctor said.
"Feels like mine is too", I commented, "Are you sure about this", the Doctor asked Flast."
"Oh yes, I'm quite sure", she replied, "How do they plan to destroy Earth", I asked, "It would only be necessary to disrupt it", she told me.
"It would still take a rather large bomb", the Doctor said, "They have one, a natural one. In fact, it's heading straight to Earth as this very moment", Flast told us.
"Holley's comet", the Doctor exclaimed, "That's right, they plan to divert it, cause it to crash into Earth. It'll make a very loud bang", she told us and my eyes widened in fear as my hearts began to race.
"Indeed, it will", the doctor said against my head, "It'll bring about a massive change in established history. The Time-Lords would never allow it", the Doctor told her.
"Who knows? Perhaps their agent is already at work", she told us, "Well, if they are, they're taking their sweet time about it. Why…. wait a minute…no, no, no, not us! You haven't maneuvered us into this mess just, so we can get you out of it. It would have helped if we had known", the Doctor yelled at the ceiling.
"You are both time-Lords", Flast asked us, "Yes", I replied, "And I'm a very angry one", the Doctor said and then sneered at the ceiling.
"I want to see the Cybermen dealt with as much much as the Time-Lords do", she told us, "Really", I asked, and she nodded.
"Surely it must have occurred to you that if Mondas wasn't destroyed, the Cybermen woud never have come here", he told her.
"Of course, but my people have accepted their fate. Your problem is to convince the Cybermen of theirs, I think I can help you", Flast told us as she made her way towards a box.
"I managed to open one of these, but I couldn't do anything with it", Flast said as she removed the lid to the box and inside turned out to be…white powder?
"What is it", I asked her, "Vastial, it's a mineral…very common in the cold areas of Telos", Flast told us as the Doctor scooped it up with a spatula to examine it.
"It's also very unstable, in fact you have enough in your hand to blow it up", she told the Doctor, before he placed the spatula back into the box.
"At this temperature though it's safe and useless, otherwise the Cybermen would hardly have locked us in here with it", Flast told us.
"It's unusual that they didn't examine the contents in here", I commented, "They didn't have the time", she told me.
"How warm does it have to be before it gets…unfriendly", the Doctor asked her, "Ten degrees above zero, then fifteen for it to self-ignite", she told him.
The Doctor walked over to the door to examine it, "Even if you could get it open, the guard in the corridor is armed", Flast told us.
"So, you said, however the Cyberman won't expect us to be armed as well", the Doctor told her, "And we can use the minerals to fend them off", I added then Doctor gave me the other sonic screwdriver he had in his coat. Thenmade his way over to the box as I tried to find a way to open the door.
"But were in here and he's out there" Flast told us, "Have a little faith", I told her.
"Alright, first things first, how much of this do we need to destroy the guard", the Doctor asked, "Very little", Flast said as the Doctor scooped up a small amount of the mineral and then made his way back over to the door.
"Have you found a way out", he asked me, "I believe so, but what will happen to her", I asked, "Flast won't be able to survive above zero degrees", the Doctor said in realization as he turned to face her.
"You can't leave here, the warmth in the corridor will kill you", the Doctor told her, "Destroy the guard first, then we'll discuss it", Flast told us, he hesitated before turning back to face me.
Then he nodded, "Okay", I said worried as I turned around and then opened the door, the Doctor placed the Spatula outside, we closed the door, and took several steps back. At least until we heard an explosion outside and then we opened the door again to see the Cyberman lying dead on the ground.
"When they learn of this, they'll kill you", the Doctor told Flast, "They'll simply complete a job they started some time ago", she told him.
"But we can't let you do that to yourself", I told her, "My dear…we are already dead, this is what I've been waiting for Time-Lords. There is enough explosive in here to annihilate Cyber Control", she told us.
"Doctor", I said, and he turned to look at me as my mental barrier fell, "We, can't let her kill herself", I thought, and he sighed, "She's already made her choice", he thought back. Then he held out his hand for the sonic screwdriver and I looked at him sadly as I handed it to him.
"Well, there's not much power left in this lance and that stuff is very cold", the Doctor said and then handed the sonic device over to Flast, "It may not generate enough heat."
"The Cybermen will not leave Telos", she said as she held the device in her hands, "Goodbye", I told her, "Goodbye, Time-lords and do not forget the Cryons", she told us, then the Doctor held my hand.
"Now go", she told us and then we ran out after we gave her a guilty look, we ran all the back to the Tardis. Then we hid as we saw a Cyberman guarding it and when we tried to go back, a Cryon popped out of nowhere and then they pointed their gun at us.
"Hello, I'm the Doctor and this is Acacia", the Doctor introduced as we both had our hands up in surrender, "Hello", I said awkwardly.
"Unless you help us, neither of you will be very much longer", she told us and then Peri popped out and then ran to us.
"Doctor! Acacia! You guys escaped, you've got to help me. They want to destroy the Tardis", Peri warned us.
"Well, that's not very friendly", said the Doctor, "No, not at all", I commented as we glared at the Cryons who seemed to have surrounded us.
"It would be more accurate to say that we do not wish the Cybermen to control it", the Cryon that popped out before Peri told us.
"That at least we can agree with, how many Cybermen are inside of the Tardis", asked the Doctor asked, "We have no way of knowing", replied the Cryon.
"Then we must find a way", the Doctor said as he walked past her and then around a corner, then he attempted to push his way through a glass door by ramming into it. It did not work…
The Doctor and I grabbed our arms in pain, "Doctor, you're going to need something stronger", I told him amused and in pain.
"I know that", he told me as a Cryon walked towards the door, but not before giving me an amused look and shot the door open.
We all walked in to find an old Cyberman lying down on the floor, the Doctor knelt beside it. Then he removed it's face and began messing with the wires inside.
"What are you doing", I asked, "The Cybermen have an in-built distress signal. I activate it, it may draw out the other Cybermen out of the Tardis", the Doctor told me.
"And when they come here", I asked, "Be prepared to run", he told me.
"I don't understand, the Cyberman is dead", Peri told us, "Well, it is mechanical not organic", the Doctor told her, and then I looked sadly away. I knew there was something more to these Cybermen…
The Doctor glanced at me and I stopped my train of thought, "…There may be enough power left to power to left in its battery to transmit the signal. The Cybermen have one weakness…they'll react to the distress of their own kind", the doctor told us as the Cryon from before walked up to the Doctor and I.
"When we were prisoners in Cyber Control, we met a friend of yours", the Doctor told her, "Flast? But I thought she was dead", the Cryon said confused.
"If she isn't, she soon will be", the Doctor told her, "Doctor", I said quietly, "She's, at the moment, the living detonator of a bomb that could go off and kill us all- ", "Doctor", I shouted, cutting him off.
The Doctor activated the Cyberman, "Alright, there's no need to shout", he said as he stood, "Doctor...don't you think you ought to tell them "that" much kinder", I told him
The Doctor sighed, "Perhaps I should learn to word things better, I'll do it more in the future. Come on", the Doctor said as we all exited out of the room and hid behind a wall to watch the Tardis.
Then the Doctor asked if the others were ready and they nodded as the Cybermen walked in our direction. As the Cybermen approached the Cryons popped out and began shooting them, at least until one of the Cybermen shot one of the Cryons.
When the group of Cybermen that came out of the Tardis were all dead, the Cryons held their friend as she died. The three of us, the Doctor, Peri, and I, all looked sadly down at them.
"I'm sorry", the Doctor told her, "I am too", I added, "Please…remove your Tardis from Telos, before you have to be rescued again", the Cryon tod us angrily.
"What about you", I asked, "We shall survive", she told me. After saying our goodbyes, we made our way to the Tardis, at least before Peri stopped us.
"But Doctor, Acacia, What about Lytton? He's been captured by the Cybermen", Peri told us and I narrowed my brows at her, "That should make him happy", the Doctor told her.
"You don't understand, he's working for the Cryons", she told us, and my brows lifted in surprise as a Cryon showed herself from around a corner.
"For you", the Doctor asked the Cryon, "Yes, for us", she told him, "Well, you guys can't just let him die", Peri told us.
The Doctor and I sighed as he approached the Cryon, "Where's he likely to be now", the Doctor asked, "Are you alright", I asked Peri, "I'm fine, I'm just worried about Lytton", she told me as the Doctor came running back.
Then we all entered the Tardis and we materialized inside of the Cyber Controller's Laboratory, when the Doctor and I exited the Tardis we noticed that the Tardis was back to being a police box.
We were relieved, at least until we saw Lytton one of the cells as he was slowly transforming into a Cyberman. The Doctor and I then ran to the cell and opened the door, the Doctor told me to stand back as he tried to free the man.
"You must kill me", Lytton told us as his voice sounded half robotic, "We can help you, hold on. Acacia try to find a machine to reverse the transformation" the Doctor told me.
"Right", I replied as I searched around the different machines to see if any did just that, "The drug is affecting my brain, irreversible damage", Lytton told us as the Doctor pulled out another screwdriver to try and help him out of his cell.
"I'm the Doctor, I'll tell you if it's irreversible or not. Now hang on, Acacia", the Doctor said urgently, "I'm looking", I said frantically.
"I did my best, kept my word", Lytton said sadly, "I know", the Doctor replied, "Acacia", Lytton called, and I looked up, "I'm sorry, I'm so sorry. Please, you must kill me", Lytton told me, and I looked at him confused, just as a Cyberman entered the room.
"Move away, Doctor and Acacia", the Cyber Controller, I assumed, ordered. I moved away from the computer and towards the Doctor, just as he placed something in Lytton's hand.
"Emotion is a weakness", the Cyber Controller told us as he approached, "We don't think so", the Doctor told it and I glanced at the Doctor before looking back at the Cyber Controller.
"It brought you back for your friend, it caused you both to protect each other, and now it will cost the two of your lives", the Cyber Controller told us as he approached, pointing a gun at us. Then Lytton snuck up behind him and stabbed the Cyberman with the screwdriver as the Cyber Controller screamed out in pain.
Lytton continue to stab the Cyber Controller until it dropped its gun and the Doctor was quick to grab it, before more Cybermen came into the room. The Doctor shot them and the Cyber Controller as they tried to attack us, when they were all on the floor the Doctor and I covered our faces as each of the Cybermen exploded a little as they died.
The Doctor and I breathed a sigh of relief, "That wasn't so hard", he told me, and I smiled amused, then I frowned, "Lytton", I exclaimed as we ran over to him. The Doctor checked his pulse, but he was dead.
"I must help him", the Doctor told me and I looked sadly at him, before I slowly hugged him, "I'm sorry", I told him, he hesitated before he hugging me back. We both looked regretfully at Lytton as Peri walked out of the Tardis and went over to us.
We separated, and I looked up at Peri, "We were too late", I told her, "There's was nothing you guys could do", she told us.
"Why didn't he say anything", the Doctor said, "You didn't give him the chance", Peri told us as we all entered the Tardis, I hesitated before going in. Then the same light engulfed me, then pulled me forward through time, and I will still remember the man that I misjudged so harshly. I thought this regretfully.
