Author's Notes: Thank you so much for all of the kind reviews. I hope you enjoy this chapter, too!

I had a really nice review from a reader in Poland that I've managed to (mostly) translate. Will the next part be happy? Guess we'll have to see;)

All These Things That I've Done

by Kristen Elizabeth

It happened so quickly. One second he was in the home he shared with Rose, and in the next he was standing on a desk...

...with a very irate red-head screaming at him.

Not all that unfamiliar.

"Who the hell are you?" the girl demanded. "And where the hell did you come from?"

Ignoring her, John quickly scanned the width of the cavernous room, taking in the glass cases and artifacts. "Is this the Delirium Archive?"

"Congratulations, you know where you are," she snapped. "Now, what did you do with the Doctor?"

With that one word, the girl had his complete attention. "The Doctor?" He jumped down from the desk, landing in front of her. "Where is he?"

She took a step away from him. "Don't play stupid! He was right there, where you are, and now he's gone and you're here, so I'm going to ask you one more time...what have you done with the Doctor?!"

John raked his fingers through his hair. "Oh...this is bad. This is very, very bad."

The girl let out a quiet snort. "At least we can agree on that."

Just over her shoulder, John suddenly noticed the achingly familiar outline of a bright blue police box. He swallowed, his Adam's apple bobbing just above the collar of his shirt. Instinct compelled him to run towards it.

"Stop right there!" the girl commanded, hot on his heels. He reached the TARDIS only to find it solidly locked. "Good luck getting inside!" she taunted. "Only the Doctor has the key and..."

Closing his eyes and praying it would still work, despite the Human half of his DNA, John snapped his fingers. Before he even looked, he knew the door had opened. He could smell that wonderful scent of what had once been his only home, metallic and earthy at the same time, and could hear the vessel's creak and groan welcoming him back.

John opened his eyes, looked into the TARDIS and immediately frowned. "What's happened to it?"

The girl followed him inside. "How did you do that? Who are you?"

"Blimey..." After taking a moment to look around, John bounded up the steps to the console. "He didn't just redecorate; he redesigned!"

"You know the Doctor, then?" The girl watched him closely. "You've traveled with him, too?"

"Oh...you could say that." He ran his hands over the controls, seeking out the familiar amongst the new. His head snapped up. "Wait, you're his companion?" The girl nodded, as if he was an idiot who'd finally caught on. "But where's Donna?" When she just gave him a blank look, John advanced on her. "Donna? Donna Noble? Ginger hair, big mouth, half-Time Lord?" He grabbed her shoulders. "Is she all right?"

"I don't know!" the girl shouted, throwing off his hands. "I don't know who she is! It's just me here; no one else!"

John stepped back, running his hand down his mouth. "What's your name?"

"Tell me yours first." After a moment of silence, she gave in with a terse, "Amy. Pond."

"How long have you known the Doctor, Amy?"

She shook her head. "No. I'm not answering any more of your questions until you start answering some of mine." Her eyes narrowed. "Where is the Doctor?"

A moment passed as they warily watched each other. "I can already see why he picked you, Amy Pond." Sniffing loudly, John whipped off his glasses. "That's a brilliant name, by the way."

Amy blinked. "So I've been told."

"You've got cheek, Amy, lots of it, and although we've just met, I have a feeling there's more that's brilliant about you than just your name." John paused. "Yet...you don't recognize me at all, do you?"

"Should I?"

"He's regenerated." The simple statement echoed off the TARDIS walls, lingering in the air between them. Shutting his eyes, he sighed. "Must have been a rough one."

Arms tightly folded, Amy leaned forward. "Who are you?"

John's eyes flew open as he began to put the pieces together. "Hold on! If I'm here...then maybe he's there!" His jaw clenched ever so slightly. "With her."

"Where's that, then?" Amy was two seconds away from stomping her foot. "Who are you? Tell me!"

"Humans!" Blinking out of his momentary reverie, he threw up his hands. "Two universes get tangled up in one great, big cosmic disaster, and all you care about is names!"

"You must have travelled with him; you sound just like him." Amy pressed on sharply, "I'm very Human and proud of it, so why don't you just tell me your name?"

It was her turn to glare at him until he finally gave in. "John. John Smythe."

"Now was that so hard?"

John smiled without mirth. "Tell me this, Amy Pond. What was the Doctor doing right before he disappeared?"

In answer to the question of why it happened, I offer the modest proposal that our universe is simply one of those things which happen from time to time. -- Edward P. Tryon

Although he'd been farther away from Rose, the Doctor was the one to catch her before she fell. As soon as he had her in his arms, he sank to the floor, cradling her as gently as possible.

Rose. Beautiful, brilliant Rose. Darker roots in her hair, but still the same delicious freesia scent. In fact, there was only one real change in her since the last time he'd seen her kissing his clone on the beach in Norway.

One large change that he could feel kicking against his arm.

"Rose?" As her lashes fluttered, the Doctor tucked a loose lock of blonde hair behind her ear. "Come on, Rose. All the way awake."

Pete stood over them, agitated and confused in equal amounts. "You can't be the Doctor. It's impossible."

"You know me, Pete. I like impossible." Rose's eyes opened and the Doctor smiled. "There she is, now. Sorry about the shock," he apologized, lowering his voice for her ears only. "Always seem to do that to you, don't I?"

Her forehead wrinkled as she tried to lift her head to look around. "Doctor?"

"That's me; I'm here." The Doctor pointed at his face. "New new new Doctor, remember?"

Rose started to sit up. "What's happened? Pete?"

"I don't know, love." Her father took her hand and helped her to her feet. "He keeps saying he's the Doctor, but he can't be."

She pressed her hand to her belly. "Yes, he can. He is...I think." Looking down at the man in question, she struggled to keep her voice from wobbling. "You regenerated?"

Nodding, the Doctor stood up. "Yeah. I did."

Hot tears welled up in her eyes. "How?"

"Radiation poisoning," he replied, straight-faced. "It was for another good cause."

Her lip trembled. "Where's John?"

"John?" The Doctor frowned, then realized. "Oh. Him." He lifted his shoulders. "I'm guessing he's probably where I was, but that's only a wild guess. Could be wrong. Are you two...?"

"No." Rose blinked back her tears before they could fall and gestured to her stomach. "I did this on my own."

"Really?"

She glared at him. "This form's a bit thick." Her gaze slipped down. "Where's your coat? I loved that coat."

"Can we talk about coats and such later?" Pete interrupted. "I, for one, would like to know exactly how John disappeared, where he's gone, and how we ended up with a Doctor who doesn't look anything like the Doctor!"

"I was dying; I changed my face; life goes on! Now, then..." The Doctor turned towards the wall at the far end of the room. "Purple?" he asked, indicating the paint that covered only half of it.

"Lilac," she corrected him. "Why does it matter?"

"Why did you stop painting?" The Doctor glanced back at Rose; her face was pale. "Maybe something you found on the wall frightened you? Like, say, a crack?" The fear in her eyes was all the answer he needed. "I was afraid of this."

"Afraid of what?" Pete asked.

"The crack. The big, scary crack the wall." The Doctor nodded. "Yes, I see it now."

Rose took a shaky breath. "John was trying to figure out what it was when he..." She steeled herself for whatever his answer might be. "Do you know what it is?"

"Nothing much. Just a rip in the fabric of time and space."

"Oh, only that?"

The Doctor flashed her a grin, but it was nothing like the smile she was used to. "Cheeky Rose Tyler never changes." His eyes dropped to her protruding stomach; he quickly refocused on the wall. "Our universes are pressed together; they always have been. That's why they're so much alike." He tapped his temple in deep thought. "I was on one side; he was on the other. And now we've switched."

"Can you switch back?" Rose asked softly.

A second passed. "Do you want us to?"

All it took was one look at the distress that overwhelmed his daughter's face for Pete to jump into action. "All right, enough of this! Rose, I'm taking you to the hospital."

"What?" She shook her head. "I'm fine, Dad. We both are."

"You passed out, sweetheart. It's just to be on the safe side. Your mother will kill me if she finds out I didn't make you get checked over." Pete hesitated. "So will John."

"Go with him, Rose," the Doctor said. "Take care of yourself."

Rose watched him run his hands over the wall. "All right," she agreed. "But you're coming with us."

He turned around, genuinely puzzled. "What?"

Walking to him, Rose grabbed one of his red suspenders. "I'm not losing you both. Understood?"

The Doctor lowered his chin in reluctant acknowledgement. "Yeah. 'Course." Glancing back up, their eyes locked again. "I have missed you, Rose Tyler."

She released him and the brace snapped against his chest with enough force to make him wince. "And stop using my full name." She started for the door. "It's weird now."

He flicked her a salute that seemed eerily out of place.
