Predictions for The Legend Of Korra Book 2

Speculations on possible connections in TLOK Book 2, mostly wild guesses going on nothing, but keep bouncing around in my head:

1. possibly Mako / Bolin descendant from Azula

2. possibly Asami descendant from June

and lastly: Pabu, in a former life as Bela, killed Asmodean (WOT).
