This is something I found on Tumblr. I don't think it's true, but it could have happened!

"Potter, can you stay behind for a second?" Professor McGonagall asked.

"Sure Professor." Harry said, though he was confused. What did Professor McGonagall want with him? He hadn't done anything wrong, as far as he knew.

Sure there had been the whole flying a car to Hogwarts thing two weeks ago, but nothing else had happened.

"Now, I know that you don't need anymore reason to hate Voldemort," McGonagall started. "But I feel like this is something you should know. I was one of the few people who did, other than Alice and Frank Longbottom, Sirius Black, Remus Lupin, and Amelia Bones."

Now Harry was even more confused. Alice and Frank Longbottom? Who were they? Were they Neville's parents, or relatives or some sort? Who were Sirius Black and Remus Lupin? And who was Amelia Bones? Was she related to Susan Bones, that Hufflepuff in her year?

"I'm sure that none of those names means anything to you." McGonagall sighed. "Do you happen to have that book that Hagrid gave you last year?"

Harry nodded, taking it out of his bag. He always took it with him. McGonagall took it and flipped through it until she reached a page and then turned it back to him. "This is Alice Longbottom, with her husband Frank. Alice was a good friend of your mother's. In fact, they were best friends. They each decided when they got pregnant around the same time, that they would be the godmother for each other's child. On July 30th, 1980, Alice gave birth to Neville Frank Longbottom. The next day, Lily gave birth to you."

Harry blinked. He and Neville were godbrothers? Why had nobody ever bothered to tell him?

McGonagall flipped to another page. "This is Remus Lupin. He was a good friend of your father's. He applied for guardianship over you when your parents died, but because of something he couldn't help, his request was subsequently denied." She sighed again. Obviously, whatever this Lupin guy was ostracized for, Professor McGonagall didn't like it.

She turned the page again, to the wedding photo of his parents. She pointed to a guy standing next to his father. "This was your father's best friend, Sirius Black. A lot of people believed that he was working for Voldemort since he was their secret keeper, but Sirius would never do something like that. He and James were like brothers. I would have gone to his trial, but the date was never publically stated. I haven't heard from him in…oh…eleven years now. I think that they must have changed the secret keeper at the last moment, but never told anyone."

Harry took note of this. So this Sirius Black was supposed the person who betrayed his parents to Voldemort, but according to Professor McGonagall, this wasn't something that Sirius would have done. If he ever met the guy, he would at least hear him out.

She flipped the page to a picture of the Longbottoms, Lupin, Black, and his parents dancing. Black was dancing with a witch with bright red hair, dark blue eyes and was laughing. "This is Amelia Bones, the aunt of Susan Bones, and the fiancee of Sirius Black. They were supposed to get married that winter, but because of him going off to Azkaban..." McGonagall trailed off.

"Anyways, only the six of us knew what I'm about to tell you. Lily had only found out about it the day before, and they were going to tell their friend Peter Pettigrew but they died before they could." Professor McGonagall said. "Lily was pregnant with her second child when she died."

Harry felt all the blood drain out of his face.

If Voldemort hadn't come...he would have been an older brother?

"I felt like you should know, since I'm the only person that could tell you at the moment. I was James' god-mother, which is why I know." McGonagall said.

"Thank you, Professor, for telling me." Harry said quietly. "Do you think you can dismiss me from my other classes? I don't think I could make it."

"Of course. I'll let Filius and Binns know." McGonagall said.

So apparently J.K. Rowling has revealed that Lily was pregnant when she died and somehow talked James into making Severus Snape the godfather. I don't see this happening, seeing as how Snape was a Death Eater at the time.

Plus, I couldn't find anything about J.K. Rowling actually stating that in an interview.

So it's probably just a headcanon, but what the hell! Let's do it!

I've always felt like there should be a reason McGonagall liked James and Sirius so much. Then I thought...why not make her James' godmother?

And I absolutely love Sirius X Amelia.

Also...how in the world did I get six reviews while writing this? Seriously - is that humanly possible? I usually only get 3 reviews before I post another chapter...
