When Aang finally met her, she asked him what he had done, bringing Tagah to the Lion Turtle Islands and the staff, only to then tell him she hid the staff in hopes that someday another Air Avatar would find it to make more Airbenders.
But how was that supposed to ever happen if not only was her name basically erased from history, but over several centuries or even millennia she never actually reached out to any Avatar, and even more so apparently actively refused any attempt at connection?
And so Aang had to go rummaging through a shit load of his past lives who had never even heard of her at all, even though she should've been one of their past lives too, to finally find some ridiculous foot fetishist who knew anything at all, with the only piece of lore about her he could give was the location of Tagah, whom she explicitly did not want to be found or brought to the staff.
If she really wanted the staff to be found and used by an Air Avatar, which after the 100 Year War and the Airnomad genocide would've been the perfect time for, she couldn't have possibly fucked this up any harder if she tried.
Even if she thought that freeing Tagah was necessary to clear the path as Aang was the only Airbender left or to find the Islands at all, which she made clear was not her intention, she still could've reached out before Aang actually recovered the staff or Tagah tried to kill Aang's friends.
So why would she possibly wait until all the damage was already done, only to then basically blame Aang for her own mistakes?
