"Is this your sonic screwdriver?" Ginny had come back with Ron ten minutes later. She threw the contraption on the table.

"Ah, brilliant. Brilliant." The Doctor sprang up and grabbed it. He waved it around and it flashed green, making the humming noise as it did so. Clarke immediately jumped up and yelled "Expelliarmus!" The Doctor's wand was thrown back again, and he stumbled a few paces back.

"For god's sake, man" Amy rolled her eyes. "What is with this paranoia? Anyone can see this idiot's harmless."

"Thank you, Amy." The Doctor said. "But that repulsion field was extremely cool. If I just adjusted the settings..." Clarke looked at the Doctor in the look of disbelief that now looked normal on his face. "Ah, good. Now, have at me scoundrel." He said, flourishing his screwdriver. "I've been wanting to say that for centuries" he said, looking back at Amy and Rory.

"How dare you." Clarke growled. "Stuepfy" He cried. But the red stream coming out of his wand disappeared as it came into contact with the Doctor's screwdriver.

"Haha!" The Doctor crowed. " I knew it wouldn't be hard to dissipate the-" Ginny glared at him. "Will you shut up?"

The doctor was about to answer when Amy cut in "No. No, he doesn't. Get used to it."

"Back to the topic..." The Doctor half-yelled "I took on the job last night, and-"

"Get this through your head, muggle" Clarke glared. "This is not some 'job' you can just take on. You can't even use magic."

"But he could stop it." Harry cut in quietly, and Clarke fell silent. He was young, but he commanded a lot of respect. "If he could stop a stunning spell with some seconds of fiddling, he might have some way to fight the dementors."

Clarke's face purpled but he didn't say anything. Instead, he stalked out the room, muttering something about guard duty, and stuffing that screwdriver somewhere unpleasant.

"Finally, someone with a bit of sense." Amy sighed. Ginny still looked at Amy with distrust, but Ron seemed to accept them.

"So, these dementors." The Doctor pronounced the last word with relish. "what are they?"

"Harry looked at Ginny and Ron, then answered "That's...hard to answer. We don't know what they are and how they work. Shacklebolt already told you most of what we know."

"Typical Londoners." Amy muttered "Absolutely bloody useless in a crisis."

Ginny glared at her. "At least we don't turn up out of the blue and leech of these useless londonders. Bloody welsh."

"Oi." Amy protested "I'm scottish."

Ginny rolled her eyes "Can't think why I couldn't distinguish that difference." She smiled slightly, then said "So what can a doctor do to help us?"

The Doctor smiled at her. "Well, the first things doctors normally do is to conduct autopsies."

Harry shook his head. "The department for the Regulation and Control of Magical Creatures have called dibs on all the bodies for examination."

Ron snorted. "I thought becoming an auror would've made you more like Moody, mate. Since when were you so polite?"

The Doctor raised his eyebrows "Moody?"

Amy cut in before Ron could answer "And now you know how everyone else feels. Ron, don't answer."

Ginny and Harry looked at Amy funnily, but the Doctor went on. "Not a problem. I can just zip in and out. But I'll need my TARDIS."

"Your what?" Harry asked

"It's an acronym." The Doctor said as he stood up. "It stands for Time And Relative Dimension In Space."

"It's that police box we came in" Amy said as she followed the Doctor.

Rory followed, and Harry and Ginny got up as they followed the Doctor to his TARDIS.

A/N: Yes, not much happens here. But this is still the reconciling stage where the wizards don't realize the Doctor is awesome. Things will speed up by chapters 6 or 7
