So this is my personal theory on who Chief Bei Fong's father is. The logic seems pretty sound to me, however the outcome I'm not sure how I feel about it. Sorry for the sloppy writing (still getting used to my pen ^.^
It says: So a lot of people want to know who is Bei Fong's Fahter. Well my friend noticed the notch in her hair. Like this. Which looked like Katara's. Whose related to Sokka. Who if you look carefully has them too. My theory is Tokka happened. I'm not sure how i feel about this.
These characters are from Legend of Korra and Avatar Last Airbender. They don't belong to me.
