"Come on Dean, we're gonna be late!"
Dean smiled as Sam bounded up to platform nine and three quarters. He was barely taller than the trolley, and Dean hoped it would stay that way, Sammy was growing way too fast, and he did not want to be shorter than his little brother.
He stepped through the platform, only to be greeted by his best friend, Castiel, with his trademark wonky Hufflepuff tie.
He laughed at Castiel's robes, which were always a size too big.
"I'd thought you'd grow into those robes already!"
Dean exclaimed, pulling Cas into a hug.
"At least I don't look like a lumberjack- what's with the flannel, I don't think that's school regulation Dean."
Dean rolled his eyes.
"Cas, we're in fourth year now, following the rules is for little, whiny first years."
Sam tugged on Dean's robe and frowned.
"Hey, I'm not whiny!"
"Well you're whining right now, hey look Sammy, why don't you go join the other first years and make some new friends!"
Sam sighed.
"But Dean, dad said you have to look after me!"
Dean crouched down, so he was eye level with Sam.
"Listen buddy, today's your first day at Hogwarts, and I know you're nervous, but trust me, you make some friends now, the day will be a lot easier. I mean, look at me and Cas, we made friends on the first train ride to school, and we're still friends today- and Cas still hasn't grown into the robes he was wearing on the first day!"
Cas lightly slapped Dean's shoulder and pretended to be upset.
"Hey!" He whined.
Sam laughed.
"Okay Dean."
"Okay, Sammy."
Dean watched with a smile as his brother approached the gaggle of first years crowded around the train, waving goodbye to their parents.
Sam turned around to Dean and gave him a wave.
"Stop calling me Sammy!"
"Never!"
Dean yelled back, he flashed Sam a quick grin before turning to Castiel.
"Don't worry, he'll be fine."
Cas gave Dean a reassuring look and placed his hand on his shoulder.
Dean stared longingly into Cas' blue eyes.
Their silence was interrupted by the abrupt whistle of the Hogwarts express.
"Come on," Dean said, racing ahead of Cas, "don't want to be late on our first day." He leapt onto the train with a chuckle, Cas rolled his eyes and followed closely behind.
