Q turns back to face him, nodding. "I haven't been to a healer," he says simply. "I woke up in the hospital here in Margate. The muggle doctors did what they could."
"I guess," Q says helplessly. "I didn't either but that's the only explanation I can think of." He swallows. "I was dying and I didn't want to. I remember something silver and," he shrugs. "That's all til I woke up." He's not telling everything naturally. He has no idea how Lucius would react to knowing that he'd been possessed by Voldemort.
He clears his throat. "Er, Mr Malfoy? I was told you might have an owl that I could use? I'd pay of course. I don't want to buy one, I just need to rent one."
