[X] A Wizard's Staff Has A Knob On The End
"Ah. Narcissa Black - Malfoy, now, I suppose. Elmwood, 13 and a half inches, phoenix feather; very slender, if I recall correctly. How is it treating you?"
"Well, thank you, Mr Ollivander," Mum says.
You wonder if she's seeing the same guy you're seeing. Ollivander seems like the kind of person Mum wouldn't even bother to tell Dobby to turn away from the door; she'd just have the wards set to fry him on entry and purge the Earth of his creepiness. But here she is, calling him 'mister'. Just goes to show if you're useful enough people'll put up with anything.
The actual wand-search doesn't take much longer than five minutes, and soon you're leaving the shop with 'Pine, eleven inches, phoenix feather, ideal for cursebreaking'. That last bit threw you; it doesn't sound much like you. You're more interested in casting curses yourself, though of course you don't say so in front of Mum.
Where to next?
