No, Ahsoka
is not a gray Jedi.We’ve
discussed what it means to be a Gray Jedi in length here,
here
and here.
To sum it up, the he Grey Jedi thing is from the Old Republic when the Jedi
Order was very different from the Prequels. During those days the force-sensitive
were more free to explore the Force and their powers, and some of them who
lived outside the system (used both side of the Force) were called Grey Jedi. Once
the Sith was gone and the Order was reformed the term Gray Jedi was used to
describe Jedi who clashed with the Council. It was more of a derogatory term (“this
Jedi doesn’t obey the Masters”) than an actual title. Qui-Gon is called a gray
Jedi because he didn’t blindly followed the Council and their teachings. That’s
it.Ahsoka is
not a gray Jedi because she is no longer a Jedi. And, by Old Republic’s standards,
she wouldn’t be one either because she doesn’t use the Dark Side. During the
Prequels no is described as a real Gray Jedi (balanced use of both Light and
Dark without any political affiliations).
