Diana had very much been looking forward to that day - it was a rite of passage in the Wizarding World, the day one finally had the opportunity to acquire the various materials that would help them throughout the first school year; and, more importantly, the day when their first wand would be purchased. It was an important day in Gideon's life and she battled heaven and hell to be able to be present, despite her crippling schedule.
It caught her off guard that the Fairgoods had requested her to bring Theodore along to purchase what he needed for his second year. Even if she didn't get along with the boy too much, she couldn't exactly deny the request: she lived in the couple's home after all, and to do so would be nothing short of rude. An Apparition to Narragyambie and some involuntary retching later on the part of the young boy, and they set off to pick up Gideon from the Whitlam Bilby dormitories.
"Now, where should we start...?" Diana pondered aloud as the trio wandered down Tallygarunga Road. They had to go for Theodore's books, even if Gideon's were already covered for; it felt like where they should go first, if only to get the obnoxious young boy's things out the way and so she could properly focus on Gideon's big day. "Let's buy Ted's books first. You get to look around in the meantime, hm?" The blonde led the pair into such a store, and let Theodore go gather whatever it was she needed while standing near the entrance of the store.
Wrapping an arm around her brother's shoulders as a simple gesture of affection, she smiled at him. "How are you feeling? Ready to start a new chapter of your life?" The mild pun brought a smile to Diana's own lips as she was a writer by trade.
