The hustle and bustle of Kings Cross Station looked to be almost too much for Molly Weasley. She was walking briskly, carrying a large, knitted handbag, and dodging in and out of little clumps of Muggles who had stopped to hug and say goodbye. Trailing behind her were six of the seven Weasley children, the seventh, a two-year old Ginny Weasley, was held in the arms of Molly's husband Arthur, and was kicking her legs wildly. Many parents, struggling with their own one or two children, stopped to look at the large family, comprised entirely of redheads. And then looked fondly at their own children, grateful that they had two, and not seven.
"Come along, you lot!" Molly called over her shoulder, in an exasperated kind of voice "Bill, Charlie, walk faster of you'll miss the train!" Two boys near the back of the group perked up and they jogged up to meet their mother.
"Now listen to me, you two," she said, pulling them over to a brick wall in between platforms Nine and Ten, "Firstly, stay out of trouble, I don't want any owls home this year!"
"Yes, Mum." They chorused.
"Secondly, Bill, I want you to look out for Charlie. This is his first year, and he needs someone to watch out for him."
"Yes, Mum," Bill repeated, as Charlie' shoulders visibly slumped. He did not like being looked after.
"Alright, then. It's almost eleven o' clock, so you'd best get through and onto the platform," she swooped down quickly and kissed them both on the cheek, "Now go on, or you'll be late!"
The two boys turned back to face their family. Their parents and the remaining five children were watching them, so they waved happily and dove through the barrier. Platform 9 and 3/4 was just as busy, if not busier, than the regular King's Cross platforms was. Students ran elbowed their way though the crowds, shouting "Hullo, Bernie!" or "Oh, Agatha! It's been ages!" and a portly man was walking around the edge of the platform, levitating a series of trunks and luggage, and shouting, "Move along! Out of the way!"
Charlie watched it all with very wide eyes until the clock struck Eleven and the train shot out a blast of steam.
"C'mon, Charlie." Bill said, tugging him by the crook of his elbow, "We've got to get on the train now." Charlie followed his brother through the crowd and onto the train, amid more shouts from students and bellowing parents. Once on the train, Bill maneuvered Charlie into a compartment.
"Okay, so, you'll be okay on your own here, right?" Bill said, glancing behind him, "I've got to meet my friends, but you've got your books, and Exploding Snap, oh, and a lady with a foot cart will come to your compartment 'round noon, and you've got some Sickles for candy?"
Bill didn't wait for Charlie to answer before he said, "Alright, see you!" and raced out of the compartment. Charlie could faintly hear a female voice shouting, "Bill! I was wondering when you'd show up!" before the noise disappeared altogether and Charlie was left alone.
