Derry was on Hugo Duty. Her parents had plans, and she got to spend the whole day with her little brother. Hugo Ferrier, coolest little kid on the block. She'd been super busy lately and hadn't had the chance to spend as much time with her family as she liked, so she was spoiling her bro a little.
The first stop on their day of fun and adventure was Weasley's Wizard Wheezes. Derry knew their 'rents never got the chance to bring him down to Diagon Alley, so she wanted to show Hugo all the cool exciting things that were there.
"C'mon, kiddo." One eye trained on the six year old, Derry let them into the shop and sort of ushered him towards the toy stand. She'd always found magic toys fascinating, so figured Hugo would too.
"Don't run off, 'kay?"
