Just another note that I wanted to add (I can't wait until Leanne gets online so I can discuss with her!): Tonks rocks!!!
Since Sirius will not be around for the rest of the series, I'll definitely be following Tonks and all she does (mind you, my heart will still pine for Sirius. . . .). I can imagine the look of horror on the Dursley's faces if she shows up at their house during the summer (well, and also at Kings Crossing. . . ).
