Harry forced himself to smile, if only a little bit, in thanks. "I think what I needed was this," he said, though he wasn't even sure about that. "I need my son to get better," he said. "And Voldemort to be dead once more."
He half sighed, half snorted, and ran his hands through his already messy hair. "No small demands, are they?" he said. "At least the latter I can help with."
He looked at his father, smiling. "Thank you. For interrupting me, and for being here. I'm glad you are, regardless of what happens." His gaze turned towards the house. "I should head inside once more," he said. "They'll need me."
