So, last episode came out yesterday, and added some more romance topics for everyone. Mainly, the whole Makorra/Masami, Mako in general, and the possibility of a new ship featuring Iroh and Asami.
All those people that are saying "Mako is so mean to Asami, he doesn't deserve anyone", read this blog post: . It is a little long, but it sums up everything. I somewhat agree with those people. Mako isn't treating Asami as he should, it does seem as if he cares more for Korra than Asami, but he should be able to find someone eventually. He's just really conflicted right now. Remember, these characters are teens, and they already have enough on their plate, battling Amon and the Equalists along with romantic tension.
Now Asami is feeling left out and jealous, and she has reason to be. Her boyfriend's kind of been with another girl more than her, add to that the fact that she knows they kissed. But what I say to her is move on. Mako is not the right guy for you if he's making lovey-dovey eyes with someone else. I think she's starting to realize that, as at the end of the latest episode, she just watches Mako and Korra somewhat solemnly, not looking heart-broken as earlier in the episode and the one before. So, good for her, right?
Some comments are starting to show up about a possible relationship between Asami and Iroh. Now, we just met the guy for the first time for about 15 seconds tops. A ship between the two would probably not suck, but I think we need more evidence before we can really support it. Iroh would benefit Asami, it wouldn't be too bad, help her move on more from Mako, but no shipping yet, not yet.
And... yes, think that's about it. So... yeah.
