[ALL] Filibuster Fireworks Anyone?

The Hogwarts Express was halfway through it's journey to Hogsmede Station. The three o clock sun was now filtering lightly through the glass windows as the scene of rolling green hills had now been replaced with a coniferous forest overlooking a lake. Not that Sam had been paying attention to their surroundings for the past hour or so. He and some other Gryffindor boys had been daring each other and if you failed your dare then, well, it involved having to streak the full length of the train and this time Sam had to make a decision: Set off a collection of filibuster fireworks and have them rocket down the train or be the firework himself and bare his naked body to the entire student body. 

Sam had decided to make his way to the back of the train, away from the driver and the lady with the trolley. The last thing he wanted was to get into trouble but at the same time he needed to protect his dignity. As a result Sam found himself setting up a box of Soaring Catherine Wheels and Friendly Fyre, which was apparently some pun on fiend fyre whatever that was. 

Taking his wand he down the train. Nobody was along the corridor for the carriage he was on, which Sam supposed was a good thing because he wouldn't want anybody to get burnt but there was the slight problem of whether he would get burnt or not. 

Pointing his wand the boy muttered incendio. Bluebell flames fluttered from his wand and with a deafening BANG the box of catherine wheels exploded and sent them whizzing along the corridor, masking the hissing sound of the Friendly Fyre rocket whose fuse was swiftly burning down into a-

KABOOM!

Sam was pretty sure he'd lost his hearing and all that could be seen ahead was a burning phoenix that had pink and old sparkles dancing from it as it began to fly along the carriage until part of the sparks separated and became a dragon that- SMASH- shattered through the glass door into a compartment. 

Sam froze.

Ariane screamed.  You would too if you'd just been showered in glass and splinters.

She stared at the massive firework that had lodged itself under the seat opposite.  Was that thing gonna explode?  Sure, Ariane liked attention, but not the kind that came along with the grotesque features of a burns victim.

She screamed again for good measure then burst into the corridor, looking to spread panic throughout the train.  Or at for least someone to blame.

Moments later Ariane Catchpenny, a fellow sixth year who Sam recognised to be a Hufflepuff, burst from the compartment that the firework had fled into, a catherine wheel almost slicing her neck off as she did so. A sign of relief washed over the Gryffindor, although he couldn't stay too calm for much longer as the phoenix had gone further along up the train and was emitting sparks at odd angles.

'I'm so sorry!' Sam called to the Hufflepuff, rushing ahead with his wand still out. Clearly not thinking that his apology was a confession that could land him into a lot of trouble.

'Are you okay? What happened to the dragon?' 

Although Sams answers were met when he reached Ariane. The dragon was crawling out from beneath one of the seats and had it's eyes set on the pair of them. Without thinking Sam grasped hold of the Hufflepuff...

'RUN!'

Thank you Merlin.  When Ariane exited her compartment, Sam Thomas was right there apologising not nearly as profusely as she thought she deserved.

In fact, if she wasn't mistaken, he was way more interested in checking up on what had become of the firework than he was in making sure she was okay.

Bastard.

"What the hell, Thomas?" was the only thing she had time to say before he'd grabbed her arm and was dragging her further down the carriage.

Ariane shook her head in frustration as she ran.

"Have you completely lost your mind?" she gasped.  "This isn't even funny, it's bloody dangerous."

She wrenched open the door at the end of the carriage and pushed him through, slamming it hard behind them both, then tugged hard on his shoulder to keep him from moving into the next carriage.

"WHAT'S YOUR DEAL?" she shouted over the clatter of the train on the tracks and the wind in their ears.  "ARE YOU SOME KIND OF PYROMANIAC OR WHAT?"
