Sirius let his head fall into his hands with a groan of, "Oh fish fingers and custard," as his latest customer stepped aside to reveal Rose Tyler and the tall man standing beside her. The girl's brow furrowed as Sirius said determinedly, "I'm not doing this. I'm not doing this. This is not a thing that I am doing."

After a moment, he reached under the counter and handed Rose a jewelry box. "Except for that," he said firmly as the girl opened it to find a truly stunning silver and diamond necklace done up in swirling patterns and several configurations that looked suspiciously like Gallifreyan circle-script. Snapping his fingers to have the necklace affix itself to Rose's neck, he added, "That is a thing that I am doing because the alternative is having you stuck in an alternate dimension. Don't take that necklace off ever, by the way. Other than that, though, this is not a thing that I'm doing."

"What's not a thing? What aren't you doing?" Rose asked, and Sirius snapped his head up to glare at the man beside her.

"I'm not dealing with him. My situation is complicated enough without adding Time Lords to the mix," he lamented, and the Doctor's face tightened ever-so-slightly.

"Time Lords?" Rose asked in confusion, and Sirius gave her a wan smile.

"The Doctor's race. He's one of the only ones not frozen," he told her, glancing at the alien.

"You mean dead," The Doctor broke in shortly, his expression grave, but Sirius scoffed derisively.

"No, I mean frozen," he corrected, "A couple of your future regenerations got together and froze Gallifrey in time. Still there, I'd wager."

The Doctor blinked a couple of times, twitched violently, then queried, "Fish fingers and custard?"

Sirius nodded and said, "Mmm hmm, Eleven is fond of the combination. Reminds him of his friendship with Amy and Rory."

"Right," the Doctor said uncertainly, "And, Gallifrey...?"

"Didn't burn. Time messed with your memories to, I don't know, preserve itself," Sirius said dismissively, then asked, "Hey, can I borrow your TARDIS for a moment? I need to bash foreheads with a wizard."

The TARDIS flashed into existence then, and from the doorway came another Doctor and Rose. "Use mine, it's here. Unlike this twit's," the second Doctor scoffed, and the first Doctor made an offended noise.

"Hey, we were kind of busy surviving being thrown into the time vortex. Which you remember perfectly well, I'd hope," he said to his future self pointedly, but his companion merely gave a short bark of laughter.

"And whose fault was that, Mr. 'I'll fix the latch later'?" the second Rose jibed, making the second Doctor blush and the first Rose groan.

"D'you mean to tell me that you still haven't fixed it?" she asked the second Doctor in exasperation, who pouted a bit and crossed his arms.

"I've been busy making sure this minor paradox doesn't tear the time stream to shreds," he said defensively, as if time paradoxes threatened to tear the time stream to shreds every day. Then again, it was the Doctor.

"If that's what a minor paradox does, I'd hate to see what a major one would do," Sirius said as he exited the second TARDIS, "Thanks, by the way."

Both Doctors froze, swiveling to face Sirius and asking in unison, "How'd you figure out how to make it go?"

"She taught me," he said with a shrug, and at their confused looks prompted, "The TARDIS."

When they didn't change, he sighed and said, "The TARDIS is sentient."

The Doctors blinked and said, "We knew that."

"Right," the second Rose said skeptically, then pulled the Doctor back into their TARDIS by his collar and threw over her shoulder, "It's been fun, but we really have to get going. So much time to see and so little stuff to do it in. Ta!"

The door closed, and their TARDIS vanished.

"On that note, we should go too. We have to relive this encounter as our slightly-future selves," the remaining Rose grumbled, and Sirius smirked.

"Wouldn't want a paradox, would we?" he asked airily, and Rose shot him an amused grin.

"We wouldn't, that's true. See you earlier!" she said as she dragged her Doctor back into their TARDIS, which vanished a moment after.

After a few seconds of silence, Sirius wondered, "Did they get the right Doctors?"
