This is only the first season, and let's not forget they've left some other story threads open too:
1. Where did Valkorian go? What is he planning next?
2. Where did Darth Marr and Satele Shan go?
There's also the situation with the Republic and the Empire. If the Alliance wants an army, no places better than these two, which means our Commander has some serious *** kicking to do. Personally, I've hated Suresh from the very beginning and can't wait to put her down hard, same with Darth Acina. For a first season, it's been good so far. It's always hit and miss first time, give it time and it will work and build to be something brilliant.
Imagine, Jaesa Willsaam/Ashara Zavros is Darth Acina's new apprentice for example. THAT would make a brilliant chapter all on it's own.
Possibilities are endless.
