Meanwhile, The Doctor stared into his future. He watched as his future self, couldn't be more than six months or so, but he looked so old… as if they'd been through so much. He held his McKenzie tightly in his arms as if he would never let go. The Doctor watched as tears dripped down his own cheeks and dropped onto the dewy purple grass below, right in front of him.

"Come on." Pandora tugged at his arm, "Leave them… They'll be okay…" she paused, "No actually they won't just yet, but they will be. I'll see to it. Or he will." Her eyes moved from the future Doctor to the present one, she smiled wide. "He always does."

The Doctor headed back into the TARDIS and closed the doors behind them.

"This is it, isn't it… this is what changed." He said, his eyes darkened.

"I can't say."

"Why can't you, what happened?" he glared at his future daughter from across the console.

"I can't say." She said again, more sternly this time.

"Why not?!" he charged over to her and placed his hand on the sides of her head.

"No! You can't!" She tried to back away, but he held onto her.

"You're blocking me out…"

"Of course I am, I won't let you see."

"Why not… What could be so bad?" He narrowed his eyes, her eyes were closed and a single tear fell down her cheek.

Then he saw it, inside her head, the grey clouds… all of her corrupted memories. Then nothing… just a white space of nothing… but something forced its way in.

"A memory transfer." He said, taking his hands away.

Pandora gasped and started to cry.

The Doctor sighed and leant back on the console, he rubbed his chin and gazed into space.

"I'm sorry… I, I didn't mean to–"

"It's okay." Pandora wiped her eyes.

"She transferred her memories to you… but why?"

Pandora offered him a weak laugh, sniffling as she rolled her eyes, "So I could help save the universe."

"She made some mistakes… but look at you, given another chance."

"I just hope it was worth it…"

They watched the screen as the future TARDIS disappeared.

"There they go… at least I've got something to look forward too." He said, setting the TARDIS back to London.

Pandora held herself close and shuffled in place, leaning against the rails surrounding the console room.

The Doctor sighed, "Tell me what happened and I can help."

"You can't… I can't tell you…" she sighed, "It's gone, or it's not going to have been at all. That's all you need to know."

He looked into her eyes, his own dark brown eyes.

"Alright. You win." He smiled, "I'm sure you managed to stop it. Whatever it was you did."

She smiled back at him.

Jack appeared inside the console room, "Right then, I've got something for you." He said, looking over to Pandora. He handed her a large brown envelope, "And a little something to help you forget." He handed The Doctor a packet with two retcon pills.

She took the envelope and looked through its contents, official documents stating a whole life was waiting for her on earth.

"But I thought…" She tried to ask, but then saw the solemn looks on both their faces, "Back there, Madame Vastra… what did she say?"

"She told me that I have to take you into quarantine." Jack stated.

"What do you mean?"

"The amount of experiments performed on you… we don't know what could happen if you came with us… and besides. Sooner or later having you around is going to be a paradox." The Doctor sighed, "I'm sorry, but you can't stay."

"Which is why, Pandora Phoenix, you're coming back to Earth with me at least until the quarantine is over. Torchwood could use someone like you." He winked at her.

Pandora smiled at him.

"Well, there's definitely going to be none of that, thank you." The Doctor said, glaring at Jack.

"Doc… so little faith." He winked at him before linking arms with Pandora and teleporting out of the console room, leaving The Doctor all alone.

McKenzie looked up at the young Doctor and hugged him tightly.

"Thank you… for saving me." She said.

"Oh, it was nothing really." He mumbled.

McKenzie felt him hold on a little tighter before letting go. She looked into his eyes, his big sorrowful eyes, she couldn't help smiling a little.

"It's funny..." The Doctor said.

"What is?" asked McKenzie.

"Have you ever thought about how hard it is to have someone look at you... and not see you?"

"What do you mean?" she tilted her head to the side.

"The way you look at me... you see him." He smiled weakly.

"But I don't... I see you... I see The Doctor." She looked up at him, he looked down at the floor and she placed her hand on his cheek, "I look into your eyes and I see the same sadness, the same regret... The same passion and the same hope. The hope that you'll find what you're looking for, that you'll find home."

"But I found you, didn't I?" he smiled, looking deeply into her eyes.

"Yeah... you did." She teared up a little.

"I don't want to forget you." He said sternly, trying to hold back the tear in his eye.

"I promise I won't forget you." She smiled.

"Goodbye." He said.

"But it's not goodbye though... you'll see me again, I promise." She winked.

He almost laughed as he stepped back into his TARDIS.

"See ya soon, Doctor." She waved as his TARDIS dematerialised.

She turned around to see her own TARDIS, she opened the door and looked up to see her Doctor leant against the console. She ran in and embraced him. He held her close and swung her into the air.

"I missed you." She said, smiling and looking down at him.

He laughed, "It's good to have you back." He smiled back at her.

She kissed him on the lips and he gently placed her back down on the floor of the console room.

He stroked her cheek, "You know, I remember that... Now at least."

"Yeah?"

"I remember waking up and feeling so happy... For no apparent reason."

"Really?"

"Yeah and now I know. It was you, Napkin Girl." he poked her nose.

"You're never going to let me live that down are you?" she rolled her eyes at him.

He pulled out a red napkin from his pocket with 'be patient' written on it.

"Never." He smiled.

"You wrote that... back then?"

"Yeah, I told you I didn't want to forget..."

"And now you have to again..."

"But we'll remember... soon enough."

"Surely, we'll forget that too? Everything that's happened since before we got to Sanctum– But oh! Where's Pandora? Is she okay?"

"She's fine, Jack's going to look after her... I'm sure you understand why she can't stay?"

"Yes... Of course. That's going to be weird isn't it... what are we going to do about–"

Jack teleported into the console room.

"Sorry, didn't mean to interrupt." He said.

They let go of each other.

"No, it's fine..." said McKenzie wiping her eyes.

"How is she?" The Doctor asked.

"She's perfectly fine, Martha and Mickey will keep a close eye on her till I get back, and she'll be a great part of the team." He smiled, "But uh... just to make sure, you need to take that retcon..." he looked over them both, "You might want to lie down."

"So what are you going to say, when we wake up?" asked The Doctor.

"Whatever you want, but I'm gonna head off after I tell you guys the good news again." He grinned excitedly.

"You know, I quite want to find out for myself thank you very much." said McKenzie.

"Awh, are you sure?"

"Yeah, you had your fun, it's my turn." McKenzie grinned as she gave Jack a hug.

"Alright," he laughed. "But again, you might want to find a place to lie down."

"We'll see you again soon." The Doctor smiled as they headed out of the console room.

"Yeah, very soon." He grinned and offered The Doctor a salute before disappearing again.

The next morning felt hazy, it was as if they'd drank too much the night before and collapsed onto the bed. The Doctor and McKenzie lay beside each other staring up at the ceiling.

"It feels like we've been asleep for a whole day... doesn't it?" asked McKenzie.

"It feels good though," he pulled her in close to him and she laughed, "I don't think I ever want to get up."

"Oh, don't squeeze me so tight, I think I'm gonna puke!"

"Alright, alright... I suppose we should get up." He took her hand, "So, what do you want to see today?" he asked.

"I dunno... show me... show me something amazing, something I've never seen before."

"Alright, something you've never seen before, coming right up!"
