Anonymous said: has it been already established that tenzin is 51? since aang died at 66, would that mean he fathered tenzin at age 15...?

Tenzin is 51 when Korra is 17. You gotta minus 17 years from Tenzin’s age before you start calculating. So Tenzin was 34 when Aang died. 66 - 34 = 32, the age at which Aang was no longer the last airbender!
