Who vs whom??

[Brian]

No: HPFGUIDX 103055

"Brian" suggests:

Ron vs ?  Viktor...who really likes dark magic, and needs to stay away from Hermione.

Hagrid vs ?  The current Gurg of the giants.

Dumbledore vs ?  Cornelius Fudge (He'll show 'em where it's packed...in Azkaban.)

MM vs ?  Dolores Umbridge (It'll be the catfight of the century, since MM will be in high cat form.)

Lucius vs Arthur (Arthur will probably make sure that Lucius is killed by "eckeltricity," maybe using one of his plugs.)

Moody vs ?  Tonks.  "Nice one, Mad-Eye," indeed.  Tonks will have shown her true colors (perhaps for the first time in her life), and Moody will perform a "nice one" on her.

Snape vs ?  Life itself.  Thanks to his ultimate sacrifice to the order, they "won't have Severus Snape to kick around any longer."
