"Yes," George said quietly. He cleared his throat. "We couldn’t find you and had no hope of knowing where to look next, but Neville had a clue—he knew he’d been Obliviated and he’d come back with a key that had traces of a Portkey on it, so we worked on restoring his memory as best as we could. We finally did about a year and a half later. We saw you in the prison. We saw Zabini’s Polyjuiced body. My Lord had held Longbottom there for a week or so by the time you came back. In Longbottom’s memory we heard him confess to what he’d done to you and Zabini. Our next move was cracking that key until it led us to Malfoy’s home where he kept you. We were too late."
