When Draco reached out to touch his chest, Harry's eyes followed the other's hand; he was slightly surprised by how little the touch actually bothered him. He wanted to reach out to touch Draco, but he couldn't get himself to do it.<br/>"Um," Harry hesitated, not having fully realised that Draco's words had been a question. There wasn't really any reason not to tell Draco about the context of the scar, it just seemed unnecessary to bring that into this situation.<br/>"After Malfoy Manor," he started, wondering if that was enough of an explanation. His eyes flickered up to Draco's eyes once again, looking for an indication that he should stop talking. When he didn't find it, he continued. "One of Tom Riddle's Horcruxes was a locket, and the scar just kinda grew over the time I wore it."
