Mako wasn't interested in Korra. Korra, I think was a little interested in him. She liked Bolin but then suddenly there were weird feelings between her and Mako, despite Mako having Asami now. Then Bolin tells Asami about the kiss, she's upset. When Mako and Korra get together, Bolin neither Asami give them shit about it. I'd give them even more shit when they end up breaking up because all they do is butt heads.
I ship Tenzin/Asami too. It's a tragic story how that has to happen...ahem...
Anywho.
Tenzin being a hardass to Korra is sort of the point for the pair. He sees a lot of potential in her, she doesn't want to apply herself and instead focuses on Pro Bending. After making a mess of Mako and Asami, she actually feels like shit and decides she can't really have friends her own age yet because she's still a bit new to the city as a whole. People are complex as fuck and she's learning she is too. So she decides to focus on her air bending while avoiding Mako, Asami and Bolin because Amon is a serious threat, girl. Meanwhile Pema is feeling overworked with the kids while Tenzin continues to give more attention to the Avatar who is slowly making progress. Finally right? Pema watches as Korra, an outsider, starts to make Tenzin smile and laugh more than he has in years. The kids start to grow fond of Korra too and before Pema knows it, Korra is helping more around the house. Uh oh.
Pema then suggests that Korra go back to her friends on the mainland and have some fun, Korra tells Pema she has plenty of fun hanging out with Tenzin and the family, and that she feels more welcome and accepted by him than with anyone else. As Korra's skills improve, she and Tenzin begin to confide about their fears, their past, etc. He tells her about Lin and Pema and Korra talks about how she fucked up Mako and Bolin and Asami. During one of Tenzin and Korra's arguments about training stances and movement, Tenzin positions himself behind Korra to correct her posture and bam! They're very close but unlike the usual instances, there is a mutual intensity and longing bubbling under the surface. His arms around her waist, she leans back...they kiss. Tenzin is of course the first to pull away and put distance between them, knowing how terrible of a mentor he has been, as well as a husband. Korra insists what they feel is natural and a connection neither can deny.
Korra acknowledges it may have been a fluke and that she'd happily go move in with Asami or the boys if it would help. She also says that he makes her feel good about herself, even when she doubts her abilities and that she wishes she could be the same kind of support for Tenzin. She says she can give him space to think if he'd like. He agrees it may be for the best so she leaves the island. Pema is happy, the kids aren't and Tenzin can't stop thinking about Korra, Amon is lurking and Korra teams with that buttface to lure him out. When Tenzin rushes to catch up with Korra who is left shaken and afraid from her encounter with Amon where he nearly took away her bending, Tenzin realizes his love for Korra is more than just that of a teacher and student that it is wrong to deny either of them happiness. Tenzin admits he's had a habit of falling for strong women and Korra says her only habit is falling in love with someone capable of catching her. The pair reconcile kiss before he takes her back to the air temple island that night where they share a bed, testing the line they've dreamed of crossing for a while now.
When Korra goes missing after being captured by Amon, Tenzin is worried sick and Pema confronts him about it, saying how disturbing it is for him to have crossed a line. He, now feeling more capable of being assertive as opposed to passive, points out Pema got in the way of him and Lin. It's a low blow but he's not sorry. He says he loves Pema and their family but that he can no longer deny that what he has with Korra is becoming special and undeniable. Once he finds Korra with Mako and co. he never leaves her side, thus letting Mako and Asami hammer out their feelings without Korra getting in the way. After the final battle, Pema moves out of the air temple island and decides she wants to be more than a mother and opens a shop in the city. Meanwhile Korra and Tenzin continue their training and head for Katara, hoping to restore the rest of her bending. While Korra considers ending it all, it's Tenzin who really does find her, they both have a vision of Aang who gives them an amused blessing.
I've rambled enough. Sorry. That's like a post right there lol
I was happy to see Korra so shaken in the middle/end part of season one. I wish they had gone back to that. And yeah, Team Avatar was more strong in ALTA, which had a fantastic last season, duh. But they said it themselves, they want to be Team Avatar, by trying to copy that alone, I think it won't ever feel the same as the original gangsters.
EDIT - Just met Opal. She doesn't seem so bad, though we'll see how that goes later on.
And we're gonna take this thing to the end man, we started it back up for a reason! XD
