Chapter 1: Caught In The Act

Hermione Granger sat on a bench on platform nine and three quarters, reading while awaiting the Hogwarts Express and her two best friends. This year was already stepping up a notch as she was notified during the holiday owl mail that she had become head girl.

"Hogwarts Express will be departing in one minute, please board," the loud speaker announced. Surely she wasn't going to miss the train and decided to board. Stepping onto the train and putting down her book for once she heard two familiar voices yell out to her, as she was always oblivious to what goes on around her when her head's in a book. Hermione looked above the crowded platform for the owners of the voices. Harry and Ron have finally made it.

"Wait!! Hermione, WAIT!!" Harry yelled.

"WAIT FOR US!!!" Ron quickly followed behind.

Hermione presented them with a smile, *late as usual* she thought to herself.

"I was going to leave without you two, and you know I would," Hermione chattered.

"Hogwarts Express will be departing now, please stand clear," the loud speaker announced.

"Well hurry up and get in here," she spoke forcefully.

Taking their seats in an empty carriage, the three friends engaged themselves in conversation.

"How have you been Hermione?" questioned Harry.

"I've been great, I assume you had an excellent time at Ron's" Hermione replied. Ron looking up as his name was mentioned.

"Guess who's Griffindor Quidditch Captain?" Ron asked looking somewhat jealously at Harry.

"Oh wow, I always knew you would make it Harry!" Hermione screamed.

"And I heard you got head girl," Harry's words loud and clear. Ron still kept that look of jealousy but focused it on Hermione.

"What about you Ron?" Hermione obviously noticed the jealous look on his face.

"I got 298% in my herbology test and I bet you will top that mark as well" Ron definitely disgusted by his mark, he could never surpass Hermione's test marks.

"Oh that's great Ron, I only got 294%," Hermione trying to sound realistic as Ron looked quite pleased with his mark after hearing what Hermione got.

"But Hermione I thought you got Three hu..oh..," finally getting the gist of things, Harry became quiet. Ron looked at Harry but fortunately for Harry and Hermione, Ron was oblivious knowing that he had finally surpassed Hermione's mark by 4% and only becoming aware of the world when the trolley came along.

"Anything off the trolley, dears?" the woman peered in offering sweets for the trip to Hogwarts.

"YES!!" The three jumped up and took their place around the trolley, eager to get something sweet and tantalising.

After filling the carriage compartment and their stomachs with Chocolate frogs, lemon drops, Berti Bott's every flavour beans, Drooble's Best Blowing Gum, Pumpkin Pasties, Cauldron cakes, Liquorice wands and a number of other strange edible items, they sat and nursed stomach upsets.

The scenery passed quickly until night when they arrived in the wizard world. They watched as the half giant, Hagrid, escorted the first years to the traditional charmed boats that'll take them across the lake to arrive at Hogwarts. Hagrid waved.

"On your left you'll be able to see the infamous, Harry Potter, who is also a student here," Hagrid sounding very much like a tour guide. Harry blushed and waved back.

"I'll see you later Hagrid!" Harry yelled across the crowed platform.

The other years were then to take a carriage back to Hogwarts grand entrance. The three friends caught a carriage with a very nervous Neville, whose face went pale at the thought of all the classes of potions he had with Professor Snape and had just passed out from hyperventilation.

"ahh..Neville." Ron poked Neville's body, which had fallen on Ron's side, "are you going to help me?" Ron signalled towards Harry and Hermione, who were quite amused at Ron's predicament as Neville's limp head was falling onto Ron's lap. "Wake up Neville!!!"

The carriage door swung open.

"What is the problem here?" Professor Snape stood there utterly disgusted at what he saw; Neville's head in Ron's lower half area.

Neville came around and quite confused at the fact that his head was where it was, looking up he discovered Professor Snape gawking at him. Neville felt light headed and fell back, only just missing Ron as he had moved across to avoid another of Neville's black outs.

"Mr Weasley, please keep your private life to yourself, especially this with Mr Longbottom " Professor Snape said discreetly.

"But Professor, this isn't how it looks, ask Harry and Hermione," Ron claimed.

"Ahh.Mr Potter and Miss Granger. you two must be the audience to Mr Weasley and Mr Longbottom's sexual act," Professor sneered, and he turned and walked off towards the magnificent building of Hogwarts School of Witchcraft and Wizardry.

"That bastard," Ron said under his breath.

"You got to admit, if I were to open the carriage door and see you with Neville's head down there I would have thought the same thing," Harry sniggered. Hermione followed with laughter.

"Shut up Harry!" Ron trying to sound serious but failed as he too finally found it hilarious.
