"Please excuse us," the Tenth Doctor said as he grabbed his past and future self and took them out of earshot of their companions. After he pulled them aside, the Tenth Doctor paused. He then said, "First off, I will not ask why me touching the both of you hasn't caused some sort of giant paradox; that's not even the most pressing issue. I would, however, would like to know why the two of you are here."
"Never mind that we just rescued you," the Twelfth Doctor said in a huff.
"My past self and my apparent future self managed to find me and get themselves chained up beside me in the process," the Tenth Doctor said aggressively. "Some rescue!"
"You realize that getting captured is kind of our thing, right?" the Ninth Doctor remarked.
"He does make a good point," the Twelfth Doctor agreed.
"And another thing! I can deal with my future coming back to haunt me, but bringing my previous incarnation into the mix?" the Tenth Doctor said. "You should know, being me and what not, that Rose cannot be here."
"Don't be absurd," the Twelfth Doctor said waving his arms about. "This Rose is from her times with him," he inclined his head to Nine, "so there's no need to worry about imploding universes. It's fine."
"And you're okay with this?" the Tenth Doctor asked his former self.
"By no definition of the word am I okay with it," he admitted, "but I'm handling."
In that instant the Tenth Doctor fell to his knees and he grabbed his head as thousands of voices filled the entirety of his mind. "What…is…happening?" the Tenth Doctor asked between ragged breaths. His counterparts looked on in despair unsure of what was going on.
Flashes of strange creatures and unfamiliar persons and planets appeared before the Tenth Doctor. He screamed in agony as he fell to the ground. "What do we do?" the Ninth Doctor asked the Twelfth.
"Residual effect of the forged psychic link," explained Twelve. "He's catching up the same as you only much quicker and that's not good."
"Can't we stop it?" Nine asked.
"Unclear," Twelve said, inclining his head. "I don't recall any stories of this happening before." At that point the Tenth Doctor began to glow with regeneration energy. "That is not good," Twelve then said.
A burst of the regeneration energy flashed upwards into the sky and the entire sky illuminated the same golden color the Tenth Doctor was. Huge bursts of wind blew across the grounds of Buckingham Palace as tornadoes began to form from the golden sky.
"Even I know this is bad," Nine said.
"Ingenious," Twelve remarked. "We need to get him to the TARDIS immediately."
"What about Rose and the others?" Nine asked.
"What about us?" Rose asked from the distance. She saw the Tenth Doctor and fear flashed across her face. "What is happening to him?" she asked.
"We'll explain as soon as we get back to the TARDIS," Twelve said. He then reached down and grabbed the Tenth Doctor from under one of his arms as the Ninth Doctor followed suit on the other side and they both hoisted him up.
"Where is the TARDIS?" Clara asked as she followed behind with Rose and Donna.
As though on cue the sky was filled with the sound of not one but three TARDIS' materializing. Everyone looked up as the most miraculous act took place. The Doctor's TARDIS' had materialized of their own accord before them and were now spinning rapidly. Each TARDIS was spinning so quickly that only a bright, blue blur could be seen.
"What are they doing?" Donna asked.
"My guess would be that they are offsetting the temporal balance that took place when my TARDIS and his merged together," Twelve explained.
"And since this one's TARDIS was unaffected it is able to help fix the rift that was formed," Nine said as he motioned towards the unconscious Tenth Doctor.
Suddenly each TARDIS was blasted simultaneously from an unseen force. The three TARDIS' were blown out of the sky and out of sight. The Tenth Doctor was becoming much worse and it was beginning to affect the other two Doctors as well. That is when a beam of light hit the group and summoned them upwards into the sky.
"What is going on?!" Donna asked.
"Your guess is as good as ours," the Ninth Doctor exclaimed.
"Oi, watch it with the lip," Donna retorted.
"Just remain calm," Twelve said. "I'm sure they want us angry and confused. It won't help."
"Isn't that your thing though?" Clara asked. Twelve shot her a nasty look just before they found themselves on board an immense spacecraft.
"They summoned us aboard their ship?" Clara asked.
"No," Twelve said suddenly. He stood up and looked around, taking in his surroundings. "I've been here before." He then looked to Rose.
"We're back," Rose said as Donna and the Ninth Doctor tended to the Tenth Doctor.
A high-pitched cackling sound then could be heard from all around the group. A large metal door opened before them revealing that they were on board the very same warship that the Twelfth Doctor and Rose had been on earlier.
The Ninth Doctor stood up slowly realizing exactly where they were. "This can't be," he said simply.
"It is," replied the Twelfth Doctor, "an old warship of Gallifrey. Rose and I were on it earlier and it seems to me that we're finally about to meet the pilot."
"Too right you are, Doctor!" came the voice of a female. A woman wearing a black and white laced dress appeared before them. She was all too familiar to Clara and the Twelfth Doctor but the others didn't recognize her. "I'm so very sorry I didn't catch you earlier, but I am here now!"
"Missy," Twelve said, recognizing his lifelong nemesis formally known as the Master. "I see you've stolen something else from the High Council," he remarked.
"Oh please," Missy replied, rolling her eyes. "Don't talk to me about stealing. Besides, it takes more than a TARDIS to escape Gallifrey these days. Ever since you ran away they're always upping their security."
Missy's eyes then wandered to the other two Doctors and a smile spread across her face so wide that one might compare her to the Cheshire cat from Alice in Wonderland. "Well isn't this just precious? It isn't too often that I get more than one of you, Doctor."
At that point the Ninth Doctor walked over to Missy taking her in. "Still alive, I see," he remarked. "I must admit your form is rather becoming."
"Oh Doctor, you flatter me," Missy said. A rather sour scowl then appeared on her face. "Don't you want to know why I'm here?"
"I could care less, to be honest," the Doctor said. "In fact why are we even bothering listening to her? She is the Master for crying out loud!"
"Yes yes, by all means," Missy said, "do spare me the entirely meaningless existence that is life. I couldn't possibly be of any use to you."
"I'm for it," Nine said.
Twelve at that point stepped in and faced his former self. "You've shared my memories, your memories in years to come. You know we can't."
"I don't know that," Nine said. "With how much death and destruction comes with her."
"Maybe he's right," Clara interjected.
"Not you too," Twelve said. "Besides, if we don't get her help he will die and everything that happened after him will cease to exist and create quite possibly the largest paradox even a Time Lord can conceive."
"Which would not bode well," the Ninth Doctor agreed.
"Right then!" Missy said clapping her hands together with a smile. "Before I even think to help you, there's just a small favor I have to ask of you."
"What's that?" Nine and Twelve asked together.
Missy, for the first time, set her eyes on Rose Tyler and with a sinister grin said, "Kill Rose Tyler."
