He sighed, his breath ruffling her hair as his arm tightened around her. He was silent for a few moments, until Hermione wasn't sure whether he'd even answer, but then he sighed again and cleared his throat. "When Mother and I first came back here, it was right after the Battle of Hogwarts. I'd just watched dozens of people I knew, including my own father, die horribly, and I was stuck in the house where even more atrocities had been committed." His fingers drifted over the scar on her forearm. "I was... not alright for a really long time. Whenever the memories got too much, I destroyed one of the rooms  he  had been in." Hermione found his hand with hers, squeezing reassuringly as she dropped a kiss on his bare shoulder. "Mother started remodelling them since they were ruined anyway, but she got sick pretty quickly and became too weak to do complex magic, so the rest have just sat there. I've had no desire to revisit them."
