Issui squints slightly as she looks down at Madarame. Since she's behind Shinobu she is fortunately out of the path of his sprawling. "I don't know, sir." She tilts her head the other way, complete with awkward lurching. "You've already heard more than I have."

Which is even true. It's also true that she probably wouldn't share any details even if she had them. Issui doesn't know Kuchiki well, but she's always been polite and easy to work with. That's good enough for her where her squad mates are concerned.
