Unification

Harry had the train's radio turned to the Pan Wizard/Muggle broadcasting network for the "Mallard Fillmore Freedom And Drinkin' Show".
"M'kay. So."
"Close to ...well, about a decade ago, it's revealed to the world that all those nice stories we read about the wizard Harry Potter, and the evil, nasty Voldemort, and Dumbledore...who was a little light in the loafers, if you know what I mean, and I think you do...are all true."
"Leading to the revelation, and subsequent unification of the "wizard" and "muggle" worlds. "Muggles" are what wizards call good, hard working, NORMAL Americans like you and me, folks. Oh, and you normal Brits, too, eh wot? I apologize for leaving you out."
"ANY-way..."
"It was all 'good in the hood' at first...trade relations between the 'wizard' and 'muggle' worlds proliferated....hey, normal kids could have broomsticks , Chocolate Frogs, and Bertie Botts Beans. What a concept. "
"But...what about the numbers of Hogwarts, Durmstrang and Beauxbatons graduates helping the Coalition Of The Willing fight our War On Terror? OH, THAT'S RIGHT, THERE ARE NONE."
"No wizards willing to help us. They'll take our muggle money, but have you seen a single wizard helping in Iraq?"
"Something's wrong folks. NOW, rumor has it that HP is allying himself with the legendary Slayer who helped destroy a Southern California town a few years back...to what purpose ...no one can say..."
"Hilda, turn that damn thing down, it's distracting." Harry said to Broom Hilda, his assistant.
It was a....very different sensation, Buffy thought to herself, flying at twelve thousand feet in British airspace in the former Hogwarts Express. As she took a sip of the pumpkin juice Harry had very thoughtfully provided, she asked him, "So....when was it for you?"
"When was what?" he asked.
"The first day you realized you were different?"
"Hmm...guess it was the first time I turned a teacher's hair blue...it wasn't something I wanted to think about too much....No...really, it was when Hagrid visited me that first time we were locked up in the cabin off of Dover."
"Really? The letters didn't do it for you?"
"No..not so much....i mean, they could have been a prank,couldn't they? Anyway...how about you?" Buffy pursed her lips and thought a minute. "Amery High,freshman year. When Merrick first showed up" The memory drew asmall tear...or looked like it would. "Then, next thing, I burned down the gym...and it was off to Sunnydale...and the rest is history." Hilda came hobbling in from the engine room. "Reaching American airspace in a hurry , boss. Is it gonna be Townsville, or Philly first?"
Harry thought a minute. "Best be safe and make it..." All of a sudden, the skies outside the window grew dark, blotting out the sun. Harry, Buffy and Hilda went to the windows to be confronted with the sight of a platoon of United States funded Biblemen astride flying atomic horses,carrying what looked like lightsabers. The Biblemen were dressed in kevlar armor designed to resemble the Batman costume Michael Keaton wore, but with a glowing cross on the chest."Oops." Buffy said.
"I'll be fucked," Hilda muttered.
"Here's the ironic part....Uncle Vernon sold drills to theWolfram, Hart and Peterson outfit to make those weapons."Harry said."Attention, flying train. You are violating American air space. According to the anti-magical terrorist protocols , unless you identify yourselves immediately, you will be blown out of the sky. God bless you."The occupants of the train looked at one another nervously..."Relax gang,"Buffy said as she brought out a white cellphone with what looked like a cartoon smiley face and a red nose..."I got it covered...." She hit the button and spoke into thereciever,"Hi Girls...I know it must be past your bedtime, but if you would converge on my coordinates, this is a Code Red....time to save the day."
