Kina is almost certain to bring this up.
Edit: A Quincy's strength doesn't seem proportionate to the amount of reiatsu they release at any given moment. I mean, otherwise Mayuri should have known just how good a Quincy Uryu would be when they fought. I'm wondering whether a skilled Quincy or an unskilled Quincy would actually be more or less likely to be targeted by Hollows. Nothing in the Manga indicates as such.
