I don't think there's a guarantee Mari will mention it, and we'll still be stressed about it in character since we won't know what the result of that potential discussion was. If I had a solution, I would have said it, but talking with hostile observers listening in isn't my forte. I still belive a solution exists, since last time our error was a matter of mispeaking, not topic. It seemd like all of the ANBU were busy in the tower, and since he is Jiraiya, he could probably be left unguarded. Though now that I think about it, they wouldn't want to leave him with Mari unobserved. It matters little, since we should assume we're being observed in any case.
