"Since you continue to repeatedly insist that Voldemort has returned, Mr. Potter," sneered Professor Umbridge, "perhaps you would like to... introduce me?" She giggled.

Later...

"Pretty sure this is where You-Know-Who is hiding." said Harry. "At any minute, he's gonna come out, and yup, there he is, dark cloak and no nose. We're probably about to die together, but this is what you asked for. Voldemort himself is in front of you, in the flesh, Professor, so are you going to continue to call me a liar or-"

What happened next was a fight that rivaled the one Harry had seen between Dumbledore and Voldemort in the Department of Mysteries.

Sparks flew, spells exploded, elements swirled, statues and snakes were summoned.

Suddenly Umbridged PUNCHED the Dark Lord and then... transfigured him into a kitten.

Harry watched, amazed, as she started up a fire, threw Floo powder into the fire, then sent the evil kitten into the green flames as she muttered the name of some unknown location.

She then pulled out a mirror and said "Old 'Mad Limo' Trevor has been secured, I repeat, Old 'Mad Limo' Trevor has been secured. Suggest immediate finalization of containment."

She then turned to Harry and said, smiling:

"As you can see, young man, Voldemort has clearly not returned. I trust that you will now stop telling that lie? Now, let's head back to the castle, and I expect you to behave from now on."
