Why doesn't Hagaromo reveal the secrets

[Senju Bean]

Hagaromo knows everything about the Rinnegan

He could have given them a heads up about Limbo.

Or about Madara's upcoming powerup

 

[Tantalus Thief]

You have a point. Maybe he had limited time

 

[My Username]

He is scared of lord mad

 

[Mad Daz]

Because it would ruin all the building suspense about how strong madara will be.

 

[a banned cartoon]

Maybe each rinnegan user gets different techs compared to the others.

 

[My Username]

Because he knows that ramen guy(hogromo's brother) would save the world!

He may have. Remember, we don't know what the Sage and Sasuke talked about. As for why it hasn't been shown yet, dramatic suspense.

 

[KillerbYo]

Ehhh.....who cares....he is not perfect.

 

[NineSNS]

I think sage was trying to correct his past decision of favoring one son over the other. After he got that off his chest, he's done with the world of the living.

he might have told them something off panel..​
