This week's episode was more on track with what I expected. Not that I don't like character development, I just think last weeks lovey-dovey triangle was a bit much, and they had to make Bolin so immature. From what I remember at the beginning of the series, Bolin was a set to be a player, always bringing fan girls into their dug out, showing them a good time. Doesn't seem to be the picture they were painting when he turns into a sniveling cry baby as Korra tries to kiss his brother. (He did get over it quickly though).
Amon must be related somehow to one of people Korra keeps seeing in the Aang memory flashbacks while she gets KO'd. This last one showed a flash of a guy that seemed to be arguing with Aang and the gang. I didn't recognize him as anyone from Avatar, but he may be someone from the Promise comics. I'm sure he's important to Amon.
Also, Aang looks strange with facial hair. At least, I'm pretty sure that is Aang in the flashes. The statue of Aang must be from when he was younger, probably right after the end of the War? He doesn't have facial hair there.
