"Yes." Neville said, simply, because there was little point in complicating it. He was sure they'd expected Voldemort to return eventually, and Snape didn't seem surprised. "In our fourth year. He was dead by the end of seventh." And that was maybe oversimplified but it was the important part. He'd go into more detail if Snape asked but he didn't feel like getting snapped at for boring him or whatever else theblther man might come up with if he thought Neville was talking too much.
"It does." He said, then, almost reluctantly, "Thank you."
