If nothing else, he's picking up quite the eclectic retinue. It will be interesting to see how this develops. I suspect Bill's tried to hide just why Fleur left and this didn't help him. Meanwhile, I suspect Albus is now realizing that he's made one too many tactical errors and is going to be a pain to deal with 'til Harry's back, or apparently back, under his control. It might be a good time to see him off on his next great journey.
