ok guys so i was watching this video that discusses each episode of LoK, and this guy said some pretty crazy stuff.
1. Amon cannot energybend. Aang's hand placement is different from Amon's. Aang has his thumbs on both the forehead and the sternum, while Amon only has one hand on the forehead.
2. There are only 3 more episodes left to Book One: Air. Korra has to learn air by the end of the season, but all the traditional methods aren't working for her. One of the guys on the show suggested that she is going to find her own way to learn airbending, and in doing so, possibly create a more advanced form of airbending (like metalbending or lightningbending). I think this is entirely possible.
