Korra is at least distantly related to Yue
In the Northern Water Tribe, unless things have changed, the chiefdom is hereditary. Currently, Korra’s uncle Unalaq is the chief (& very spiritual…makes sense) and the prince & princess are Desna and Eska. Which means they are all decended from Yue & her family in some way.
Yue is at least a (n-th) cousin or (great great…) aunt to Korra.
My mind is just blown with this realization.
