Lol, how does Khivas know how heavy Javik is? Is Javik standing on a scale? Because as far as I know, the Force doesn't tell him the weight of another individual. Just a thought.
Hoy! If, at some later point, you want to do an old fashion Master-Padawan mission for the Jedi, I could see that being a lot of fun. Not to mention it would be good story development.
