Harry and Ollivander have this conversation in Deathly Hallows after Malfoy Manor detainment.
‘Walnut and dragon heartstring,’ he said. ‘Twelve and three-quarter inches. Unyielding. This wand belonged to Bellatrix Lestrange.’
‘And this one?’
Ollivander performed the same examination. ‘Hawthorn and unicorn hair. Ten inches precisely. Reasonably springy. This was the wand of Draco Malfoy.’
The words "belonged" and "was" are in the past tense. Is Ron Weasley the master of Bellatrix Lestrange's first wand?
