I’d have to suggest something my mentor Mitth told me….
You are a Jedi when you feel it.
No one else can tell you when you make the shift from apprentice to Jedi, or even from Jedi to mentor. You just KNOW.
But Nitro is right. Such distinctions are irrelevant when one’s character is brought to light. I don’t really know or care when I actually made those transitions. I just care that I am who I have chosen to be.
