Harry's eyes widened slightly at the mention of a child. In the midst of all this horror, a pregnancy, a baby seemed almost a foreign concept. That didn't really ease his mind much, though, because he knew what it was like to grow up without parents.
He didn't know how to argue with a parent's need to fight for their child, though, to make a better future for them. He didn't want the child to have to grow up in this world, either, but what if they died and nothing had changed?
There wasn't any room to argue that point, though, he could tell. The years had taken the fight out of Harry on this argument, too. At least Neville seemed level-headed and realistic about it, he wasn't going to do anything reckless.
"I think there are only two things left," he said, scuffing his foot against the ground in an expression of anxiety. "We think that his snake has to die before-- before I can do what I'm meant to do."
It was weird, explaining this to someone who didn't even know about the horcruxes, about what they'd been doing all these years. Even the Death Eaters that had saved Ron's life had come to them with an idea of what needed to be done, but that was because they were Death Eaters. Harry hadn't found that odd, because who would know better what they were up against than someone who had gotten close to Voldemort, been someone that Voldemort trusted? As much as Voldemort trusted anyone.
He still wasn't sure that he was telling Neville this to ask for his help, or to comfort him somehow, to tell him how far they'd come and what was still to be done.
"He has-- they're called horcruxes," he said. "Pieces of his soul, that keep him from dying. They're not easy to destroy, but the snake should be the last one. We've found the others."
