@ Blix: You're right, she does say that, though as with many TV series of this type, stuff tends to fluctuate as the series progresses and what was said in the past can sometimes be lost or ignored.
Much like how no one really cares about how Maul may or may not have been in other EU work, they just want him in their TV series to make it fun for a certain group of people. I mean, come on, is this really the first time that there's ever been an EU conflict? From what I know of the EU, it's just a huge mismatched collection of cluster****s people spend too much time trying to piece together into one cohesive timeline.
I think, over the years folks have gotten way too caught up in the seriousness of the EU and have forgotten the fun of it being extra little stories.
