That line from Bib Fortuna, "Bargain rather than fight? He's no Jedi." doesn't really make sense.
Surely the Jedi have a reputation for negotiating first and only fighting when necessary.
It would make more sense if he said something like, "Bargain rather than fight? He certainly sounds like a Jedi."
He would probably keep the same tone of disdain.
It would also bolster the idea that Luke has become stronger in the Force since we last saw him.
