It's stuff like that why I'm always touting how great rebels is. They have this entirely self contained story and they've been able to seamlessly integrate events and characters from the movies without it feeling forced or shoehorned in for a cheap pop. Not to go on a Lucas rant, but I don't think he could've come up with a simpler/cooler "time travel" idea that fit so well.
I loved clone wars the same way, and watched Rebels up through the last season. But we moved, and I had to redo my DVR que, by the time I got around to it I had missed most of the season.
Yeah it's pretty perfect. It's kinda that whole thing I have always wondered, and touched it JUST enough without being like HERE it is!
