Tenzin is Kataras third child though, Bumi should be yours because Kataras first was you and then either Kya or Tenzin is your child (depending on if she was sleeping around). This is a meta theory but Katara does imply she sees you again before bk3 so if you knocked her up again that would mean all 3 would be yours. Though not genetically but I like to think all of MCs spiritual children end up being extra perverted (hard to tell because so many characters in this are perverts).Li is Toph daughter
suyin is That girl on that lotus city daughter (related to Toph too)
Tenzin is Katara son so everyone in his family are related to the main character.
Im just saying I dont think that was the first time Suyin was swinging with airbenders. And Tenzin has been implied to be getting around in bk4 love. Theres definitely no correlation. Actually.. this would explain why Tenzin wasnt sleeping with Pema very often.. the guys been cheating on her the entire time. What kindve guy needs to be asked for more sex?I strangely thought of that when i was with Opal and was like, how someone that should be full earthbender turns out a airbender? Then i remember Book 3 and was like... oh right... all that cum inside with Aang's body...
