I didn't know she'd directly referred to that - it's interesting & I do appreciate that she has attempted to respond to the zillions of questions fans might still have. I find that I tend to think of anything published as canon, & her many comments as somewhat less so - partly because my Lit background places an emphasis on published work perhaps, and partly because comments & answers can be fluid & varied, depending on how she might view a character as any given moment. Although (just to contradict myself) I do see Dumbledore/Grindelward as canon now. *g*
