AN: here comes some history, more pulled together than sirius version, hope that you like!
The Doctor had simply been minding his business, after dropping of that Cooper. One million pounds enough for drinking money? He snorted.
Just as the Doctor had started to think about what he was gonna do next, he got a shock.
That couldn't be true. That couldn't happen. He double checked, then he triple checked. It was true. A man was really materializing underneath London, in all that garbage. The Doctor wrinkled his nose. He had to pick that man up, which he did, thanks to his amazing, sexy TARDIS.
Rassilon, that man wasn't looking quite that healthy. He had to take him to the hospital in New New York. Best human hospital there was, and good for a lot of other humanoids.
There, he found out who the man was, when he, the man, woke up.
Sirius Black! In the flesh! From the Harry Potter books. The Doctor was giddy. He had now met Sirius Black!
Though he had also found out what had happened to Sirius, and what the veil was.
When Sirius was okay again, he brought him to the TARDIS. Sirius didn't seem surprised at the least that the TARDIS was bigger on the inside, a ship couldn't be as small as a police box. The Doctor wasn't that happy over that. He liked the normal reaction, but of course, Sirius being a wizard, probably already was a little more open-minded than his companions, especially growing up surrounded by magic.
But Sirius was still quite predictable. He cared about the people he considered his family, so, naturally, he asked about them. The Doctor didn't like telling Sirius that Godric's Hollow didn't exist.
Something that he could've predicted had he actually thought about it, was Sirius reaction when he found out about the books.
He would've reacted the same way had, as an example, he wasn't ego-centric or anything, he found books about himself, one for every regeneration. I'm the Oncoming Storm, face my wrath!
The Doctor could predict what would happen next; Sirius was going to have a breakdown, if he didn't, he needed to see a therapist. The Doctor better start looking into that.
AN: please review, and tell me what you think. it's the reviews that keeps me going!
