As a side note, would just not being allowed anywhere near Ikeda be the logical thing to do? I can imagine everyone forbidding Hazou from going near her after a leak like that
Yep, there are two ways to look at that.
1. On the one hand, yes, Hazou was just seduced by a fellow competitor leading to an OPSEC breach and should be ordered to stay far away from her.
2. On the other hand, if a Hazou who seemed smitten with Ikeda stopped interacting with her the moment he leaked her his secret, that'll look suspicious
too, especially since he started showing interest only when the Gouketsu needed a cover-up.
We could play a you-know-I-know-you-know n-level deception game here, but consider this: Hazou leaks a secret to Ikeda, he then act suitably sad, but he is still allowed to interact with her later. Why? Perhaps because said secret wasn't actually that
serious — which is consistent with our "Kurosawa bloodline secret" explanation. It's not scaleable, it's something the Kurosawa have always had, the status quo remains.
So I think having another meeting is a slightly better idea, especially if Hazou will manage to act his part as well.
I think you misread the intent there. I specifically said "disinformation campaign", not "read in on the full details of the opsec breach".
I'm afraid that'll be enough. Hazou tanking the explosion apparently raised quite a few eyebrows. Even if Ino didn't start to wonder, do you think
Shikamaru missed it? And if that very day Hazou will take part in some kind of "disinformation campaign" that requires him to be drunk with Ikeda, do you think Shikamaru wouldn't connect the dots? It'll be obvious that whatever trick Hazou used, it was strategically important.
... I could add thanking her for looking out for Hazou/apologizing for not listening, if you want?
