"Um..." Harry had to think, had he had dinner? Had he even had lunch? "No, I haven't eaten, but you don't have to go to any trouble. I'll pop through now." He reached for another handful of powder and stepped into the fireplace. A dizzying moment later he was stumbling out into Ernie's small flat.
He managed to keep most of the soot in the fireplace and not on Ernie's rug, though his robes weren't so lucky. He cast a quick cleaning charm, then wished he hadn't when his shoulder reminded him it had been wrenched forward and back too many times to count. It could be he was in worse shape than he'd thought, but he still didn't want to go to St. Mungo's. He hoped Ernie could patch him up here with no trouble.
