hi! i'm cj, and i play Narcissa and Kingsley (shackled). i'm sure both of them would remember him when they received their wands (and wee Narcissa probably wrinkled her nose at him, judged~ him, but took the wand anyway lolol snob). it won't be some years until Cissa's bb!Draco will need a wand, but hey future customer!
as for Kingsley, who knows where his auror work might take him. he might just need a new wand one day! or maybe he randomly strolls into the shop at some point. i'm good with anything :)
