I was really disappointed with the role Wormtail played in this new book. It was almost like a cameo appearance... like Elizabeth Hurley in The Spy Who Shagged Me, if you will. He appears for ten seconds as Snape's little bitch and then disappears again never to enter into the story again. Rather like dangling the old carrot in front of the string if you ask me. But Rowling has always been good with that, and this is one of the least clothes-tearing juicy (^_^) examples.
And I usually don't pick on your Shimraanese, but I took particular delight in "Cumbledore." If they ever make a porn based on Harry Potter, that name has to be in there!
