Pavi and Korra
What if unlike Korra and Aang who seeked advice from their past lives. Pavi refuses to speak to Korra? We know in the Seven Haven's world that Korra is blamed for the way the world is now. All this bad mouthing about Korra being the worst avatar Pavi would hear this growing up especially since she's very young she'd obviously be very skeptical about Korra. We would see scenes of her trying to ignore Korra or drown her out. But later on Pavi would hear Korra out and understand the truth about Korra's decisions. I just think itd be a neat contrast compared to Aang and Korra who seeked advice and Pavi who ignores advice she'd need.
