A/N:For anyone who was confused last chapter, this one is meant to explain it all. If it doesn't well, I messed up :P

M.Minds

Thalia glared at all the guards around them while the Doctor kept a protective arm around his young companion. Although over two hundred years old, Thalia was from Lupercalia, where two hundred was barely childhood. She was old and young at the same time, her image manipulator making her look in her teens, nothing like either of her ages. She was the strangest companion he had ever had in his TARDIS.
The planet they had landed on, Manakalasia was a war with itself. The two of them had left the TARDIS to find guns pointed at them. Thalia had been ready to attack but the Doctor had pulled her back. The two of them were sat on crates, waiting to be told what to do.
'Excuse me?'
The two of them looked up at the alien who had called them. Judging from his uniform, he was incredibly low ranking.
'The commander wishes to speak to you. He says it's important.'
The two of them rolled their eyes before following the alien. He lead them to a small room at the back. The room matched with the aliens anatomy; the dark red walls were the same shade as the commander's scales, the bottle green furniture reflected his three eyes and, when he smiled, the Doctor noted the ebony paperweight on his desk was the same colour as his teeth.
'Doctor.' He held out his hand to shake. The Doctor raised an eyebrow; the Manakalasians didn't shake hands by way of greeting. Thalia moved so she was closer to the Doctor, continuing to glare at the commander and refusing to give her name.
'Now Thalia.' The commander smirked. 'Don't be like that.'
Thalia jumped slightly and growled. Lupercalians were most similar to wolves and it was showing. 'How do you-'
'Know your name? Why, that's exactly what I wanted to talk to you about.'
He sighed, as if trying to find a way to explain it.
'Do you remember, two incarnations ago, you travelled with a married couple.'
The Doctor glanced at Thalia. The two of them shared a conversation with their eyes before turning back to the commander. Thalia's hand was resting on her image manipulator, ready to revert to her natural form at any moment.
'Of course I remember them. What are you on about?'
He sighed again before tilting his head to the side. 'You explain it, I can't be bothered to.'
The Doctor was about to say something when the commander changed. His eyes grew softer, his mouth curled up into a familiar smile and his antennae dropped like they weren't being used anymore.
'Hello Doctor.' The voice of Rory Williams, a man from earth, 2011, came out of the mouth of the commander, an alien from Manakalia, 4062. The Doctor froze.
'Okay, not the reaction I was expecting.' The commander smirked but it was Rory's smirk, so human and normal. 'Doctor say something.'
'You died.'
Rory- because it was Rory there was no denying that- bit his lip. 'Yes. So did everyone else in here.' He tapped his forehead.
'I don't understand.'
Rory glanced at Thalia, obviously nervous about speaking in front of her. Thalia shrugged and tapped her image manipulator. Her form flickered before she stood as a Lupercalian, twice the size of an average wolf from earth. She curled up on the floor and fell asleep. The Doctor scratched her behind the ears before looking up at Rory.
'Explain.'
Rory's eyes fell slightly. 'You remember the time you looked into my mind, right?'
The Doctor shuddered but nodded. 'The four rooms in a long corridor.'
Rory smiled. 'It's more than four now. We've got about, I don't know, thirty? I'll check.'
Before the Doctor could do anything, Rory's eyes went blank. Just before the Doctor got to panicking, the life returned to Rory's eyes and he sat up.
'Thirty six. God that makes me feel old, thirty six lifetimes.'
'How is that possible?'
Rory smiled. He whispered something to himself and his eyes went blank again. He looked up and a familiar smirk took over his face.
'Did I really use to look like that?'
The Doctor froze as his own voice replaced Rory's. 'W-w-what? I-I...'
'Oh stop blabbering.' The other Doctor smirked again. 'I'm only here to explain things. I haven't been out of my room in 27 lifetimes.'
He took a breath and looked down at the floor. The current Doctor, the real doctor, saw something in the other him's eyes. He didn't usually let this show through; defeat.
'The universe never wanted me to die.' His voice was quiet and filled with so much sorrow. 'I went peacefully. I was ready to go. But I closed my eyes, expecting it to end...and reopened them. I was on Pyrovillia, looking out through someone else's eyes. I got used to living as Kaxano and then he died. And I woke up again...'
A few small tears spilled from his eyes. 'What I'm saying is...none of us understand this. I woke up again and again, each time with one more person trapped in our mind. Things started becoming plural. I was us, me was we, mine was ours. I watched Amy and Rory grow up, I felt him die. And then I heard you were here, in Santilan's base, I had to tell you. Because you never saw how special you were. We all were.'
'I don't understand.' He couldn't deal with this, not from his own voice.'
'Neither do I. All I know is the universe didn't want me to die. The same thing happened when Kaxano died. And Rory. And Artorius. And Dentrho. And on and on until now. I cannot die. Knock off regeneration.'
'I can't...'
'I know. But I will tell you this before I go. The universe will never forget you. You will be in their hearts and minds forever.'
The other Doctor's eyes went blank and someone else took his place. He knew it was the commander from the way he smiled.
'Well I hope they managed to explain things.'
The Doctor woke Thalia and almost stumbled to the TARDIS. Thalia kept talking to him but he ignored her. The TARDIS moved off quickly, knowing what was wrong. Thalia left for her room, leaving the Doctor alone. He fell against the console, unable to keep himself standing. The TARDIS floated in space as tears began to fall from his eyes. His own words echoed in his mind and he closed his eyes.

The universe will never forget you. You will be in their hearts and minds forever.

When Thalia Lunatis walked down to see her adopted father the next morning, she found him still and unmoving. She checked his pulse and heartsbeat to find them both non-existent. She cried and fell against the console. Pulling down on a lever, she set the TARDIS in motion. There was an ancient Lupercalian ritual for bring people back from the dead. She kissed the Doctor's forehead before throwing him into her home planet's sun. He would continue to live and she would see him again.

600 years on the past, on the fiery planet of Pyrovillia, a baby boy, soon to be name Kaxano Dailantos, opened his eyes for the first time not knowing that, deep within his mind, someone else opened theirs with him.
