Info: When the Doctor restarted the Universe, he restarted time. Moffat has said that everything from previous episodes still happened, but only in broad strokes. What does he mean? Maybe something like this.
"Wait—" he froze, gripping her tightly by her shoulders, staring at her wildly, "We just restarted the universe, history's been changed."
"Yeah, that's what you said," she nodded.
He let out a whoop; life coming to his eyes that she hadn't been aware was missing.
"Amelia Pond, if I'm right I'll owe you everything!" he turned, calling out, "Rory! Kiss your wife, tell her she's brilliant, I'll be back when I'm back! Darling! Rev up your engines, we got a pink and yellow human to find!"
With that, the Doctor took a running start towards the TARDIS, a door swinging open to catch him, and dove inside even as she was already fading out.
Earlier that day, uninterrupted by the mess in the timelines, one Rose Marion Tyler went about her daily routine.
Wake up, have a small spat with her Mum, catch the underground, buy some breakfast, maybe see her boyfriend, and get to work, hopefully on time.
All the while ignoring the feeling that something was very very not quite right with her life; the dreams certainly didn't help.
However, this morning she was running a bit late; as she hurried towards her platform, hoping the trains had a delay or two she heard a man call out, "Need a lift, Rose Tyler?"
She paused, whirling around to find a man and a blue box in a nearby alleyway. The man was in tweed and a bowtie and even from a distance his eyes were sparkling. He was leaning against the box like he was trying to be nonchalant but his excitement for something was obvious.
"Scuse me? Do I know you?" she asked softly, trying to understand why her heart had begun pounding and she wanted nothing more than to run to him. The melody she had always heard in the back of her mind got a little bit louder, a little bit more insistent.
He cocked his head, "Not this time, no, but you did. Rose Tyler."
"Okay, how'd'ya know my name?" she questioned, trying desperately to ignore how her knees had gone weak with the way he said her name. Fuzzy feelings of safety, of adventure, of home, of love, came to her and the feel of ghostly hands held hers.
He chuckled and she fought the urge to grin at him, felt the urge to beam because she made him laugh and that was something special.
"How could I ever forget?" he replied, "tell me, Rose Tyler; did you really forget me?"
"I dunno what yer on about mate," she stuttered out as she realized that the blue box looked awfully familiar and she had the utterly insane urge to get inside it, with him. She rolled her shoulders, preparing to leave, "Look, 'm not whoever you think I am an' I'm runnin' really late—"
He started before nodding, "Ah, yes, that would make sense. I can give you a lift, that big department store right?" he grinned, "Give me a minute, go around that corner and I'll be along in a minute."
She stared haplessly at him before shrugging, sighing, and nodding; she went around the corner and knelt down to retie her shoelaces as she waited. She didn't know why she trusted him, she didn't even know his name, and he was apparently insane, but she did. With her life.
She was startled when a motorbike came rumbling up behind her and she spun around to find the man on a motorcycle. He was grinning wildly, holding out a hot pink helmet.
"Going my way, doll?" he quipped.
For some reason she smiled widely back and replied, "Is there any other way to go, daddy-o?" before clambering behind him, taking the helmet and donning it.
"I don't even know yer name!" she giggled.
"I'm the Doctor!" and with that, they took off, weaving through traffic.
Even as he did so, the Doctor plotted.
He had Rose back, in a way, she seemed to have echoes from their original timeline but even in this timeline he had taken her as a companion so he didn't quite understand why she was still there. He could force her to remember, but that would be quite painful to her.
So, he had to gain her trust, get her into the TARDIS, and hope for the best.
He did know he wasn't letting her go without a fight this time.
They pulled up to the department store and he parked, helping her off the vehicle and taking her helmet.
"Thanks!" she said breathlessly, looking into his eyes and that feeling that she knew him intensified drastically, "You might've just saved my job."
He gave a grandiose bow, "For you, my fair lady, anything." He paused as he heard her digestive tract work, Time Lord hearing, and looked up to her, "Have you had breakfast yet?"
She shook her head, "Runnin' late," she shrugged, "I'll probably grab a snack on break, done it before."
He stood up, frowning, "Nonsense, how are you supposed to get anything done on an empty stomach; go punch in, I'll be right back with something."
Before she could protest, he had hopped on the bike and roared away.
Blinking, she was sure he was a nutter; she shook her head again and headed in to work.
It took a few hours, hours in which the 'Doctor' fellow did not return, but Rose was finally able to grab her break and as she was heading to one of the nearby vendors, intent on finally getting a bite to eat, none other than the Doctor popped back up, holding a small covered platter.
"My sincerest apologies," he said, "Got a bit distracted along the way."
He led her to a nearby pub patio and settled her in for her meal, uncovering the platter to reveal fresh pastries and other breakfast foods. From a pocket in his coat he pulled a thermos, still piping hot.
He unscrewed the top, revealing a small cup, and poured her some tea.
"Oh?" an eyebrow rose. He was now retrieving two packets of sugar and a small package of honey along with a sealed plastic stirring spoon. With what looked to be practiced ease, he poured the condiments in and then stirred. Three times clockwise, three counter-clockwise.
He nodded, "Yes, I was baking the cinnamon rolls and making the glaze when I realized that I didn't have any blueberries or raspberries so I went to visit a friend and steal her berries but she was missing her dog."
"You baked these?" she gasped in shock, even as she tore into the frankly delicious treats.
"Yes, learnt how to in France," because of her.
"You've been ta France?"
"Yes," he nodded, hiding the wince that question brought before going on, "So, my friend was looking for her lost dog so I volunteered, calling in another friend for help. We finally found the dog, gave him a severe dressing down—"
"You lectured a dog?" she snorted.
"Why wouldn't we?" he asked, confused, "K9 is a brilliant dog."
"The dog's name is "Canine"?" something about that name tickled her mind; like it was something she knew and had forgotten.
"No, no, that would be silly," he shook his head at her, "It's K-as in the letter-9, I was a very punny fellow when I found him. Things happened and I couldn't keep him so I gave him to a friend."
"So, you found K9 an' gave him a stern talkin' to," she prompted, wanting to hear the rest of this story.
"Then my friend, his owner, noticed things smelt badly. At first we just thought he had rolled in something but then our other friend fell into a…well, pit of muck…"
"Septic tank?" Rose asked, seeing the look on his face; it was a look of pure and absolute disgust.
He nodded, "Yes, as I pulled our friend out, the dog owner called the needed people. We then trooped back to her house, poor septic coated friend took a long, hot, thorough shower, borrowed some clothes of the first friend, and then headed out to her car to head home because it's her day off…."
"It didn't start, did it?" Rose was giggling now; it was ridiculous, honestly.
Had she been paying attention, she might have noticed that he seemed to bask in the sound of her laughter.
"Why, Miss Tyler, are you psychic?" he asked teasingly, grinning as she giggled more even as she shook her head.
"Nah, just a feelin'. So ya fix it or what?"
Now he pouted, "None of my friends will let me near anything they actually have to use; the other friend though, she's good with that stuff but we actually had to call in a mechanic."
"Who'd'ya call?" she questioned, knowing that some liked to hike up their prices for no reason, especially if they thought they could get away with it.
"Oh, hm," he faked recalling it, "some bloke we found in the phone directory, named Mickey Smith…seemed a bit young but he was nice enough. What?"
She stared at him, "Mickey Smith? 'bout my age, black?"
"Well, yes."
She burst out in true laughter now, gasping, "Mickey's my best friend, boyfriend too!"
"Oh, are you sure it's the same Mickey Smith?" he knew damn well it was the same man; he had purposely sought him out. It wasn't hard to get Sarah Jane on his side once he rebooted her memories. And hopefully, being around each other would trigger Mickey's and Martha's. And whatever K9 had done to the car was easily fixable by a skilled mechanic and inexpensive to boot.
She raised a finger in the universal gesture for 'give me a moment', still laughing, and dug out her mobile phone, a dingy, rather obsolete, flip-phone, hit a speed dial, and put it to her ear.
"Hey Mick," she spoke lightly when he picked up, "No, 'm fine; hey, you wouldn't be working on a car would you?"
She looked at the Doctor and he gave her the make, model, color, and registration number which she relayed.
She broke out into a new bout of giggles, nodding, "Yeah, the guy who called ya in? 'm havin' lunch with him right now; tell ya what, give his mates a discount an' I'll have Mum make that weird soup ya like."
She nodded again, humming in an affirmative way before saying goodbye, wishing him luck with the job, and stowing her phone.
"Same Smith?" the Doctor prompted this time.
"Yep, same Smith," she blinked, freezing suddenly only to shake her head, moaning a bit as if she had a massive migraine. Her eyes closed, her head went back, her back ramrod straight.
He was at her side immediately, checking her vitals, "Rose," his voice was tinged with panic, "Rose, what's wrong? Talk to me, Rose Tyler."
He was half a second away from scooping her up and rushing her to the TARDIS, he could patch her mind back together after he made sure she was alright, when she spoke, a haunting sentence, "I am the Bad Wolf, time has been restored to what should have always been."
Her eyes opened to revealing that they were glowing gold before the power faded into brown.
"Urgh, my head." She moaned, blinking, "Doctor, what happened…wait, Doctor?!"
Hope rose in him, "Rose, do you know who I am?"
She groaned a bit more, "Well, considerin' I knew two yous I figure I do know ya Doctor. Now what's goin' on here?"
"I'll explain once we get back to the TARDIS," he spoke quietly, "short story: the universe's been reset. Everything that happened still happened, broadly speaking, but also didn't happen. For some reason, there's two of you, and Jackie. One you went with the big eared me. Got separated from the converse me, and ended up with clone me…one of you didn't."
"So, I'm the copy. This me."
"Yes and no. I have a theory that this happened because the universe couldn't completely rid itself of my timeline and anything, anyone connected to it, but was also forcibly reset." He paused, peering at her worriedly, checking her vitals again, "How's your head? Your mind was just rebooted."
"Headache from hell, fine otherwise…wait, you sought me out." She blinked owlishly at him.
"Of course I did, Rose Tyler," he gave a soft smile, "We've been given a third chance, and I'm not going to waste it…unless you don't want—"
"Gods no, Doctor; of course I wanna give it another go, well, once my head quits feeling like it's got an axe buried in it. What's up with Mickey though, you called him on purpose right?"
"Him and Martha Jones married a while after the stolen Earth fiasco. If they're around each other, it might jumpstart their memories. Besides, had to get him out of the equation for now."
