Well from Book 1 it was definately ep3 because of all the roaming around the city and fighting , it was just like i thought the other episodes of the series be - new team 阿凡达 fighting equalists and exploring the city. It was also the ep that still didn't have all that pointless romance drama in it :P From season 2 it was episode 10 probably where they went in the spirit world and Korra turned into a kid (and again no 爱情 3angle drama) 或者 the first part of Civil Wars.
