The Autons outside weren’t letting up. “Come on, come on!” grumbled the Doctor as she worked the controls. She then pulled on a lever…but it didn’t move. “…Of all the-! RASSILON!”
      “What?!” asked Rassilon.
      “You jammed the brakes on! That’s why TARDIS maintenance is best left to me!” She then found a mallet and swung it at the lever. NOW the Time Rotor moved up and down again! The TARDIS made its usual takeoff noise, but the takeoff was rather sharp, knocking people around. After a good minute of shaking, the TARDIS settled down with everyone picking themselves up. “All right, sound off,” said the Doctor. “Who’s not dead?”
      “I think I clonked heads with someone,” complained William.
      “Me,” replied Amy. “You clonked heads with me.”
      “Crap. Sorry.”
      “Still alive,” said Rassilon.
      “So are we,” said Tsukasa, speaking for his fellow Riders. Sougo, Keito, and Woz goggled again.
      “So it wasn’t a dream?!” asked Keito.
      “It appears not, Geiz-kun,” replied Woz.
      “How-?!” asked Sougo.
      “It’s a bit complicated,” replied Rassilon. “First, you have to imagine a big box inside a small box.”
      “…Then?” quizzed Sougo.
      “Then you have to make it,” finished Rassilon. “It’s the second step I stumbled on a lot when I made the first TARDIS.”
      “Everyone, why don’t you all give them a tour of the place?” the Doctor suggested to her crew. “I need to input the data. Oh, Sougo, could you and your friends give me your Ridewatches? Perhaps I can pinpoint the exact moment the paradox began with them.”
      “Sure,” replied Sougo.
      “Wait a minute! Doctor, that kind of technology-!” argued Rassilon.
      “Rassilon, please!” urged the Doctor. “I’d rather not risk peripheral damage to the timeline.”
      “…Very well.” Rassilon turned to the Riders. “You heard her. We need to trace the origin of the paradox.”
      “Fine, fine,” grumbled Keito as he handed over his Ridewatch. Sougo and Woz did the same and the Doctor wired them into the TARDIS console.
      “Come on, guys!” called Amy, remembering the Doctor’s suggestion. “I know the best rooms here!”
      “There’s more?!” asked Sougo.
      “The other doors should have made it obvious,” remarked Tsukasa. Amy led everyone on a tour of the best rooms in the TARDIS with Rassilon and William stayed behind.
      “…I suppose Amy is sufficient for-,” said the Doctor.
      “Doctor, why are you doing this?” asked William.
      “…I don’t know as I follow.”
      “When we tried to undo Ezar’s transformation into a Krynoid…”
      “…Ah.”
      “So you DID say something about this kind of thing,” remarked Rassilon.
      “Her exact words,” explained William, “ were that several laws of time prevent her from messing with established history for a start and those laws spawn from the simple fact that doing that is the messiest of quick fixes that just create paradoxes out across time and space.”
      “…Those were my exact words, and I meant them,” confirmed the Doctor.
      “But you’ve decided to mess with established history right now,” observed Rassilon.
      “…If there’s no other way, yes! Look, William, there are just some secrets of time that I cannot risk divulging, and that stems from the fact that I don’t know what lies ahead for you.”
      “What’s that supposed to mean?!” snapped William.
      “William, you met previous companions of mine. There will come a time where you and I will part company and I don’t know what you’ll do or who you’ll meet or what you’ll tell them or what they may force you to tell them. The basic fact of the matter is that there are some secrets that a Time Lord must never EVER reveal.”
      “It’s something to do with the origin of the greater paradox surrounding the Autons, isn’t it?” asked Rassilon.
      “…Yes,” said the Doctor.
      “And when Tsukasa told us what was going on, you thought about something, but didn’t elaborate!” said William. “Doctor, I need to understand!”
      “William!” snapped the Doctor. She then drew in a breath to calm down. “…I’ll say this much; it has to do with the nature of the universe and the fabric of time itself. Somehow, there’s an unpredictable reaction between the two. You know what a temporal paradox is, yes?”
      “Yes, when someone goes back in time to alter the past, only their actions in the past caused the future in the first place.”
      “That’s one example,” remarked Rassilon. “And that’s the pertinent one, isn’t it, Doctor.”
      “…Yes. And that’s all that I’m prepared to say,” replied the Doctor.
      “William, I think we’d best let the Doctor work right now,” suggested Rassilon. “We’d best not interrupt her and risk peripheral damage to the timeline.”
      “…All right,” grumbled William. He and Rassilon headed after Amy and her group while the Doctor checked things over.
--------------------------------------------------------------------------------------
      After a while, the Doctor sighed. “Useless,” she muttered. “All because Tsukasa wants a quick fix. …Tsukasa… …Tsukasa…” The Doctor tapped her chin, then typed something into the console. “Timeline check on Tsukasa Kadoya, keyword: Rider Forms.” The scanner then revealed all the forms Tsukasa took as Kamen Rider Decade. “…Why is that one separate from the base form? It sure looks the same.” The Doctor checked on the form. The minor difference was that the light on the helmet’s forehead was purple instead of yellow. She goggled when she saw what that form really was. “Violent Emotion, oh dear. Tsukasa, you can’t use that form at this time!” At that moment, everyone filed back into the console room.
      “Are we there yet?” asked Tsukasa. “We seem to be taking our sweet time.”
      “…You know, you’re a bit of a mystery, Tsukasa,” remarked the Doctor.
      “Oh?”
      “I can’t think of a single reason why you’d get so angry over a minor mistake like that,” continued the Doctor. Tsukasa’s eyes went wide.
      “…You…you guessed?!” he spluttered.
      “Tsukasa, you can’t risk using your Violent Emotion form like that,” urged the Doctor. “You’ve already surrendered it when you stopped being a destroyer!” By then, a strange energy washed over everyone, freezing Tsukasa, but not everyone else.
      “Doctor, what’s going on?!” asked Amy. “Tsukasa’s frozen!”
      “Not only that, he’s phasing in and out of existence!” observed Keito.
      “That’s just confirmation of my theory,” shuddered the Doctor.
      “…But you’re not gonna tell us, aren’t you?” said William.
      “They’re the cogs of a great machine going in opposite directions, time and space crushing each other to death like angry beasts unleashed,” said the Doctor.
      “It’s getting worse, isn’t it?” observed Rassilon. “The time paradox?”
      “Yes,” confirmed the Doctor. “There are good and bad places to have them. This is a bad place, just bad luck in the game of universal dice, really. But if we don’t do something, everything could unravel.”
      “Everything?” asked Woz.
      “Everything!” repeated the Doctor. “Too large a concept to have any meaning, isn’t it? Can you imagine the chaos of every particle of matter accelerating to the point of destruction? And even destruction is too small a word! Terror, agony, they don’t even come close!”
      “So if we don’t destroy the Autons-,” ventured Sougo.
      “I’m not sure that’s what we need to do,” interrupted the Doctor.
      “Doctor?” asked Rassilon.
      “You mean you don’t know what’s caused the time paradox?” asked William.
      “I thought the nexus point was when the Autons were activated after the death of the Nestene Consciousness in 2013,” explained the Doctor, “and that we had caused that by bringing the Ridewatches there.”
      “What’s made you change your mind?” quizzed Amy.
      “Tsukasa,” replied the Doctor. “His Violent Emotion state. He’s willing to bring that form into existence again.” That was when Tsukasa started moving.
      “How did you-?!” he spluttered.
      “The time distortion’s gone,” remarked Rassilon.
      “Time distortion?” asked Tsukasa.
      “Yeah, didn’t you notice?” asked William.
      “We were outside time, everyone,” explained the Doctor. “Looking in on the impending disaster.”
      “Doctor, have we landed yet?!” insisted Tsukasa. The TARDIS then made its arrival noise and thud.
      “Oh dear, we have,” gulped the Doctor. Tsukasa then pulled out his Decadriver.
      “Then it’s time to finish this!”
      “Tsukasa, no!” argued Sougo. He, Keito, and Woz blocked the door.
      “Get out of the way!” demanded Tsukasa.
      “Tsukasa, using your Violent Emotion state won’t help this situation!” urged Geiz.
      “We’ll stop you if we have to!” warned Woz as he and his fellow Riders pulled out their respective BeyonDriver and Ziku Drivers, attaching them to their waists.
      “You can’t stop me!” replied Tsukasa as he opened his Decadriver and pulled out a card. Sougo, Keito, and Woz then pressed the buttons on their Ridewatches and Miridewatch, prompting them to say “Zi-O!”, “Geiz!” and “Woz!” respectively. Tsukasa flinched, then growled.
      “I have to do this!” he insisted. “Henshin!” He then put the card into the Decadriver!
      “Kamen Ride: Decade!” It announced once he closed it. The Ridewatch Riders then inserted their trinkets into the belts.
      “Henshin!” they all called.
      “Rider Time! Kamen Rider Zi-O!”
      “Rider Time! Kamen Rider Geiz!”
      “TOUEI! Future Time! Sugoi! Jidai! Mirai! Kamen Rider Woz! WOZ!” All the Kamen Riders were ready! Decade charged at them, but Zi-O and Geiz tripped him up while Woz pinned him down once he hit the floor. The one thing they all forgot was never let Decade reach his Ride-booker. He opened the book on his left and drew a card, then inserted it into the Decadriver.
      “Attack Ride: Slash!” it announced. The Ride-booker then unfolded into a sword and he slashed at the Riders pinning him down. He got up and ran out of the TARDIS!
      “STOP!” called Zi-O as he and his friends rushed out after Decade.
      “NO! PLEASE! GET BACK-!” protested the Doctor. She growled when they didn’t listen. “Rassilon, Amy, William, stay here and monitor the situation!” she ordered as she left.
