I was shocked when I saw Hagrid. He looked like he'd been through the wars. Sure enough, he had been off to see the giants, along with Madame Maxime of Beauxbatons---oh, yes, they're back on speaking terms, and, I gather, rather more---and things had not gone terribly well. It seemed that the Death Munchers had also thought of the giants, and their new chief liked what Voldemort's representatives had to say. There was a lot of fighting, I gathered, but that didn't explain why Hagrid still looked like he'd gone twenty rounds of bare-knuckle boxing with someone his own size. From what he said, most of the fighting had been between the giants themselves.
