It's quite interesting to watch Harry recover and rebuild himself, though I'll be interested in seeing/finding out more about that "voice" he heard. In any case, it appears that he is regenerating his abilities and that's going to worry a lot of folks when they find out. Meanwhile, it looks like he's going to have Mad-Eye watching his "six" and Hermione supporting him (after she interrogates him thoroughly on where he's been - and then gets a "mad on" over how he was treated) and that'll do for starters as he rebuilds all of himself and incidentally helps others along the way; that bit with the fishtailing truck was a very nice touch - nothing provably magic, but well applied spell work, without a wand. I suspect Moody, despite himself, is impressed.
