I know that was implied, but if the 8th Brother was a Jango jumper, then isn't it possible that he wasn't necessarily force sensitive? Like I said; the Jumpers were able to physically hang with Jedi (which the 8th Bro did) even though they don't use the force. And on top of that, I don't remember the 8th Brother ever using the force offensively. 馃槙
Again, the Eighth Brother can use the Force, and is a former Jedi...

I'm sure I can find more, but that should be enough.
