"He's Order. Someone will know where he is, or how to find him. Wonder if your brothers deal with him at all," Harry mused, shifting his weight uncomfortably from foot to foot as Kreacher bawled. "Ermm. . . I mean we can try to track some of it down. . . But we really need. . . he didn't say where he was going, did he at all? Or what he was doing with it?" Harry asked.
Kreacher had been wretched, and he was mean and somewhat hideous and definitely crazy. . . but still. Harry couldn't help but feel sorry for him. All he had in this house were those little treasures he kept. And god knows that being stuck in this house for ages would have driven HIM nutters, too. It had that effect on people. And house elves were off anyway. Having a Mistress like Sirius' mum - well. Probably wasn't Kreacher's fault he was a complete loon. They just did what they were told, mostly. Dobby was the exception, and even he really liked it when you told him to do things, he just wanted to be free while he did it.
It didn't undo the damage Kreacher had done in the past. But still. He was pathetic to look at, and Harry sighed, kneeling next to him. "If we can find any of it, we'll uh, bring it back, okay? But we need to find the locket. It's important. Is there anything else you can tell us?"
