Sooo... no one else took note of that? It makes me really curious. If he was just Force-speeding away, it doesn't seem like Sek'nos would say he wants to learn that trick because Force-speed is a common power. I also don't think it would make sense if he disappeared like Mother Talzin in The Clone Wars episode Massacre because unlike other new-yet-primitive Force powers in the series I don't see why no Jedi do that in the era we're more familiar with. It seems like something cool because I love seeing different Force powers, but I can't make any sense of it.
