The craft arrived at a place out in the Outlands of the Grid. It looked like a rock formation, but the Doctor correctly guessed that there was a hidden door somewhere. William’s observation only confirmed it. “Hang on, this is where Kevin Flynn hid,” he remarked.
      “The place was just lying abandoned,” replied the mystery woman. “We figured it was a good place to use as a bunker. It sure looked like it.” Her helmet finally vanished to reveal a woman in her early 60’s. The Doctor grinned.
      “Great to finally see your face!” she said.
      “We gotta stop meeting like this, Professor!” chuckled the woman. The two then hugged like old friends. The other woman then dismissed her helmet, revealing a Chinese woman.
      “Erm, Ms. McShane,” she said.
      “Fa Mulan!” breathed William. The Chinese woman turned to see William. “Dr. William Davies,” he said as he held out his hand. “Huge fan and admirer of how you took down Shan Yu.”
      “Nice to meet you,” replied Mulan as she shook William’s hand.
      “As long as we’re introducing one another,” said the Doctor. “Everyone, I’d like you to meet an old friend of mine, Dorothy McShane, or as I knew her, Ace!”
      “Hi!” said Ace.
      “…Are you the same Dorothy McShane that started A Charitable Earth?” asked William. “My brother’s old orphanage is under your umbrella.”
      “Ah, so he got adopted, huh?” asked Ace.
      “He’s working as the head of the American branch of your company,” replied William.
      “No kidding?” asked Ace.
      “Erm, Ace,” interrupted the Doctor, “I believe there are some questions to answer.”
      “Right. Come on, everyone!” Ace led everyone into the bunker. Under its new owners, it looked a little cluttered, compared to when Kevin Flynn was occupying the place.
      “Sorry about the mess,” said Mulan, “but we’re still trying to puzzle out a few details. Welcome to Rinzler Base.”
      “Rinzler?!” yelped William.
      “I’m not the program you saw in Tron: Legacy,” came a voice. Out stepped a program with blue light trim, a hole in his cheek where data flowed, and a face of regret and pain.
      “…Tron!” realized William. “But…how?!”
      “My User, Alan-One,” replied Tron. “He saved me from the Sea of Simulation somehow. I…I could not be fully restored…nor could I undo what I did in Clu 2’s name. But I could resume my fight for you Users. Unfortunately, Alan-One was arrested in the real world as Maleficent took over, using a disguise. She sent various Disney Princesses down here to fight for the amusement of Sark and a restored MCP.”
      “The Master Control Program, I presume,” remarked the Doctor. “How did he come back? He was destroyed bit by bit, yes?”
      “I thought he was,” confirmed Tron. “But Gantu found his old source code and the source code of another program, combining the two into a new MCP. I’ve been trying to rally other Users to my cause, but the political landscape-.”
      “Too volatile for the rest of us to concern ourselves with supposed works of fiction,” replied William. “Even using fiction to escape the stresses of the world is becoming controversial.”
      “I was losing all hope,” said Tron. “But then AcesHIgh entered the Grid and broke Mulan out.”
      “It was entirely by accident, but a happy one,” explained Ace. “I was doing something for UNIT because their agent came back terrified at what he saw. They can’t get anything out of him, Professor. He’s been catatonic for the past week.”
      “Probably because what he considered fiction was proven to be real,” remarked the Doctor.
      “I was trying to send my findings to Kate, then the MCP digitized me and put me on the Grid. …Didn’t exactly comply, though.”
      “You never did like an oppressive regime,” chuckled the Doctor like a parent with their grown-up child. “But why is Maleficent sending Disney Princesses down here in the first place?”
      “He wants our power,” replied Mulan. “We all have certain attributes that little girls admire, humility, courage, forward planning, curiosity, all that stuff. The MCP thinks we’re the best, so he intends to absorb us into him so he could study these attributes, that was the deal he made with Maleficent.”
      “Doctor, I think our goals align with theirs for the moment,” remarked Rassilon. She pulled out the tracer and pointed it in the direction of Sark’s ship. It crackled.
      “…Either Maleficent or Gantu has the segment of the Key to Time,” realized the Doctor. “And now, they’re on the Grid. …We’ll need to lure them to us somehow. And the MCP wants me dead. He singled me out so that my friends would die in the games and I would die immediately at his metaphorical hand.”
      “…That’s not like the MCP,” remarked Tron.
      “…Tron, have they ever come here?” asked the Doctor. “Sark and his forces?”
      “They scoured the entire Outlands,” replied Tron. “They never found our base. Flynn made it too well.”
      “Then we’ll have to lure them to the MCP’s base so all parties can get what they want. Now then, everyone, any ideas?”
      “The MCP will want to know your presence is real,” remarked Rassilon. “And any disruption at his base will summon Sark to his aid.”
      “If I might indulge,” offered Ace, “a hole in the wall at the citadel should do the trick.”
      “A hole you’ll create, I presume,” guessed the Doctor.
      “Naturally.”
      “And I have the code needed to defeat the MCP,” offered Tron.
      “…All right, here’s the plan,” said the Doctor.
--------------------------------------------------------------------------------
      It was a three-pronged assault. Ace, Mulan, and William would blow a hole into the Citadel, while the Doctor and Rassilon strolled through the front door. Amy and Tron would slip in through the confusion, then while the Doctor distracted the MCP, Tron would use his Identity Disc to upload the code into the MCP and derezz him, while Rassilon checked each villain for who had possession of the segment of the Key to Time. Once that was discovered, Rassilon would use the tracer to turn the object back into its original segment form and they would defeat the villains in the confusion, then send all the prisoners back to the real world and expose Maleficent and Gantu’s plan to control Earth’s governments. Once everyone was set on the plan, the craft took everyone to the MCP’s citadel. The Doctor and Rassilon headed to the door as Ace and her team prepared the explosives. The two Time Lords arched their eyebrows at the appearance of the MCP. “…Aren’t you going to get dizzy?” called the Doctor. The MCP stopped rotating and faced the Doctor.
      “Doctor!” he said.
      “…You seem to have me at a disadvantage,” remarked the Doctor.
      “Doctor, how does the MCP know who you are?” asked Rassilon.
      “Be silent, Rassilon,” interrupted the MCP. “You’re no god here. That honor belongs to me.”
      “Tell me, were you always this megalomaniacal?” asked the Doctor.
      “I’d hardly call it megalomania if it’s true,” answered the MCP.
      “MCP, I can’t say as I recognize you,” admitted the Doctor.
      “That’s because, last time we met, you were still in the world of the Users. You were a dandy at the time. Your third incarnation, I believe your Identity Disc called him.”
      “Oh, yes, I remember him,” remarked the Doctor. “A touch bitter, for my tastes. Though, being exiled to one time zone WILL do that to you.”
      “I’m sure, Doctor.” The MCP then looked distracted. “Ah, so you’ve summoned Sark here. Good. Perhaps I can reeducate him on who the master is. His…BOSS, if you will.”
      “…Why did you emphasize that word?” asked the Doctor, a nasty suspicion forming in her brain. She then heard struggling. Rassilon heard the same. They whirled around to see everyone brought into the Citadel, restrained by guards.
      “Sorry, Professor,” said Ace.
      “ACE!” yelped the Doctor. She whirled on the MCP. “Let them go or I’ll-!”
      “You’ll what?” scoffed the MCP. “Summon Kate Stewart to finish what her father started with me? Perhaps bomb the place like a typical American? That won’t do you any good, Doctor.”
      “How do you know so much?!” demanded the Doctor. “Tron said you’re a blend of two source codes! Who’s the other one?!”
      “You really don’t recognize me? …A pity. I had hoped you’d remember, despite appearances. Tell me, Doctor, if I were to tell you that the next thing I say will be true, but that the last thing I said was a lie, would you believe me?” By then, the MCP’s voice mimicked the voice of the Doctor’s third incarnation perfectly. The nasty suspicion in the Doctor’s brain grew stronger. She looked down at the floor and realized that it was a red circle with a white soundwave visual.
      “…No!” she whispered.
      “What’s wrong?” asked the MCP, making the soundwave visual move. “Nothing to say? …Are you not happy to see your BOSS?”
