Tenzin being beaten by Jinora in just about everything was just destroying his pride and making him accept that he isn't the one to lead the new generation of airbenders, but someone who can adapt, rather than convert others to a way of life long gone. I get the message, but I hate how it needed Tenzin to be a bitter asshole to make Jinora look better for pushing towards master status. Jinora and Kai lacked any meaningful chemistry last I checked, and it was bad enough it was a romance that had nothing other than 'hey this boy is kinda cute' and even AFTER she finds out he's an asshole she doesn't give him nearly as much shit as Opal gave Bolin all the time. Ikki and Meelo love their family and they sometimes go overboard when it comes to teasing each other, as shown when Tenzin had to go find Ikki (oh my god she was so precious in that episode dude ;-;), but yeah Jinora was just so ...obnoxiously good at everything she's ever done. Bumi and Kaya always felt like Tenzin was the favored child and Jinora is somewhat making Tenzin's issue come to life among the kids themselves. Jinora has never failed Tenzin and is consistently incredible, to the point Ikki and Meelo will never compare with their meager scraps of development. I don't know HOW that didn't piss them off at one point. Family rules I guess.

LOL I don't know how but we'll see if we can find a way, and we'll give you a moment or two xD
