"Yes." Neville's demeanor didn't change much but there was a little bit of something unavoidable there, "It lasted around three years, or just one depending on who you talk to, but it was at Hogwarts for our seventh year. And the final battle was there." It was a holiday now, that day, but he never did much after the first few years, it wasn't the sort of attention he liked. He wasn't sure if telling Sirius everything would really help or not, but he would have wanted to know.
"She was actually a seer." Neville told him, prepping the tea and setting Sirius' cup out for him. They were hearty stonewear mugs, rather than proper teacups, because Neville had a tendency to forget his tea around the greenhouse and it stayed warm longer in these. "But the real propheciies were few and far between it seemed." Neville was well aware of the one that could have changed his life dramatically. It didn't really make him like Trelawney anymore, but he didn't completely dismiss her either.
Neville gave a small half-smile to that huff. "I don't think I know either. They say it's almost normal again, but it still feels pretty odd." He leaned back against one of the tables along the walls of the building, sipping his own tea. "It helped." he said softly, "Everything that all of you did. And a lot of you fought again. We weren't alone."
