A/N: Hello! It's been a long time! (Sorry, I've been having exams!) I apologize for the long Chapter name. I'm very unimaginative when it comes to those things.

Chapter 11:

The Perks of being an Animagi

Sirius heard a collective gasp as they pulled the cloak off themselves. It fell to the ground with a dull 'thud', making the only noise the room had heard since Dumbledore had announced their presence to the whole gathering. The red-haired woman - Amy - was looking at him, unable to understand, and obviously in shock.

The Doctor on the other had, seemed rather excited (more so than usual) and Sirius could swear he had actually seen his eyes widen with admiration as the took of their cloak.

"How did you do that?" the Doctor asked, taken aback. "Was that a perception filter? How? Tell me!"

"Muggles." Sirius muttered under his breath. To the Doctor, he said loudly, "It's an invisibility cloak."

He was trying not to give out too much information. Rather, he was hoping that they would all assume that the two boys had just found it lying somewhere, and just decided to wear it. What he didn't expect, however, was that James might act like the idiot he was.

"It's mine." he said, seemingly embarrassed over what had just happened. Sirius didn't know exactly what James was playing at. Either he was being incredibly clever, and saving their arses with some plan, or he was being incredibly stupid and doing that 'saving thing' of his. He didn't hold out too much hope for it being the former.

"Can I hold it?" The Doctor asked, grinning like a child who just received a truck load of presents. Dumbledore, Sirius noted, was oddly quiet. He looked, Sirius could have sworn, rather amused. As though two students who had an invisibility cloak, and used it to break into his office was an everyday thing.

"Sure." James said, and threw it over to the man. Stupid of him, Sirius thought. What did he know about this man? What if he was some crazy and he had to admit exceptionally weird Ministry bloke dressed as muggle? Or what if he like it so much he kept it and refused to give it back? It sounded very, very possible, especially when this man was considered.

The Doctor touched it, and then put it over his arm. Then he took it off. Then he put it back on. The procedure was repeated a million times, him giggling childishly everytime, until, it seemed, Amy had had enough.

"Doctor! I am sure that little toy of yours is really important, but we have a problem here. That's the Crack in my Wall! How did it get here?" She said, her frustration obvious.

"It is not a toy-" James started, but Sirius shut him up by stepping on his shoes. The last thing they needed right now was for James to start boasting about thei adventures under the cloak just to win a stupid argument.

"Er... Yes." the Doctor said, sobering up, though still not letting go of the Invisibility Cloak. "The crack. Now. You two," he said, pointing at Sirius and James. "You knew that Professor... er..."

"Rottleburn." Dumbledore added, helpfully.

"Yes. How did you know that Professor Rottleburn was missing?"

"He didn't come to class." James said, shrugging.

"But how did you remember?" the Doctor went on. "How? What makes you different from the rest of the wizards?"

"We're exceptionally handsome?" James said, with a smirk.

"For the love of God Mr. Potter, this is no time to make jokes!" McGonagall scolded them, which sort of startled Sirius, seeing as she had been quietly listening to the conversation and not adding anything. He had almost forgotten she was there.

However, the Doctor's last sentence made him think about it... How they were different. Aside from the obvious handsomeness, Sirius knew what that one thing was. They were Animagi. But exactly how that was related to this situation, Sirius did not know. Besides, it was not as though he was going to announce that there were three illegal Animagi running about around Hogwarts. Dumbledore seemed to know enough already.

The Doctor whipped out a strange, pen-like device from his pocket and pointed it towards the two of them, moving it up and down as if it was some strange detector.

"According to the Sonic Screwdriver you are normal." the Doctor said, when he had pulled it back and he had examined the device to view the to him obvious, but to Sirius, obscure findings of the experiment. "However, it seems there was a slight mutation... Now that is interesting!" the Doctor exclaimed suddenly.

James exchanged a look of worry with him. Had he found out with that strange device of his? Could anyone even find out just with a small pen?

"I think, Amelia," the Doctor said looking very happy indeed, "that we are going to take these two into the TARDIS. I need some more stuff to see exactly how they acquired this ability..."

"What ability?" Amy said, obviously irritated with the Doctor's vague sentences.

The Doctor, however was not listening. "Come on, you two!" he said, glancing in their direction before promptly walking off without any further explanation, leaving Dumbledore and McGonagall with identical expressions of surprise. Amy followed the Doctor out of the room, leaving the four wizards and witch in silence.

That was, until, the Doctor's head popped from the open door. "Well, come along, now!" he said.

Sirius and James managed to move themselves, all the while hoping that Dumbledore would not realize that the previous conversation had meant.

They walked out of Dumbledore's Office and into the Hallways. On their way out from the castle, they met none other than Remus and Peter, who had apparently been searching for them all over the school.

"Where have you two been?" Remus said, almost scolding. He looked up at their companion, and frowned. It seemed he had not yet forgotten the ill-treatment his books had received at this man's hand. "Why is he holding your Invisibility Cloak?"

James took it from the Doctor at once. In all the worry over their secret being exposed, Sirius had forgotten about the Cloak, and it seemed the same had happened for James.

Amy and the Doctor didn't like them waiting.

"Can you please hurry up? There is a long walk from here to the TARDIS, and I am not fond of long walks!" Amy said.

"They're coming with us." James said.

"Yeah!" said Peter, enthusiastically. To Sirius, he added, "Where are we going?" Sirius shrugged.

"They can't come!" Amy said.

"They remembered Rottleburn too!" James said, defensively.

"Alright, alright, now can we move?" the Doctor said, finishing the argument.

They remained silent for most of the journey to the TARDIS, save for the arduous task of filling Remus and Peter in on what had happened yet. James was the one talking. Sirius, however, was silent and thoughtful. What was this TARDIS? Some sort of device? What did it do? More importantly, what did it do to Animagi?

They walked and walked till the sky became black, and eventually they were reaching the end of the Hogwarts plains, and the forests were starting. Standing there, was a lone blue Police Box, so prominent against the dull background, and so obviously out of place.

The Doctor looked at it proudly, and stroking the wood of the door, opened it, and stepped inside. Amy gestured for them to follow suit. Sirius didn't think she saw the point: the Doctor was asking four people to join him and Amy in a Police Box.

"Go inside. Come on, just do it!" Amy edged them on, obviously enjoying the moment.

When they walked in, they were taken slightly aback. It was obviously an Undetectable Extension Charm on it.

"Well?" Amy said, when she had stepped inside too. "Anything you want to say?" She looked very happy, and rather expectant.

"Oh there's no need to do that Amy, they're wizards. They've seen things that are bigger on the inside before." the Doctor said. "Though I am sure this is the best one you have seen so far because it is not magic-"

"Of course it is." Remus said, as though that settled it.

"Humph." Amy said, and walked away, disappointed.

"Now," the Doctor said, pulling a long wire towards them and moving it up and down in their faces, "let's see why exactly each of you have animal genes inside you."
