The full-cast audiobook of OOTP changed the description of Michael Corner

I don't think this is major, but I couldn't help but notice a change in the books compared to the new full-cast audiobooks. In the original text, when Ron asks who Michael Corner is, Hermione describes him as 'The dark one.'

However, in the full-cast audiobooks, she says, 'The dark-haired one.' I know 'the dark one' traditionally refers to hair color. For instance, in The Half-Blood Prince, the narrator notes that Narcissa is fair while Bellatrix is 'dark.' It’ll be interesting to see if they make similar tweaks to the Half-Blood Prince audiobook as well.
