The next arcs are something I'm wary and excited for. Either we are going to get some gut wrenching Sokka and Azula being opposing generals, or we're going to get the pair putting on a show to make it seem like things are happening while minimizing casualties on both sides with Azula letting Sokka's side gain legitimate victories without making herself look like she just letting it happen. Azula is a perfect situation to sabotage her own side in the most bloodless way she can.
... :'D
Honestly, there's a lot going on and too many complications for either side. Unfortunately, or fortunately... Azula's not exactly up against Sokka directly. Her immediate foe is... someone she's not exactly fond of. And who isn't fond of her :'D

... long story short everyone who ever complained about Azula not getting enough action (... and I mean literal action, I don't think anyone ought to think she didn't get enough of THAT kind considering what Part 2 was like, whether when we saw it or when we didn't...) should enjoy the coming arcs, ahahaha...haha...ha...
