The Siege of Lothal is best Star Wars can offer, and it takes whole series in totally new level when it connects the Clone Wars with the beginning of the Rebel Wars seamlessly. What lies in the heart of whole episode is Anakin's ... er ... Lord Vader's relationship with Apprentice ... er, Ahsoka. Sorry about the pun but from the beginning of this summer special, I couldn't stop thinking about how closely Anakin was knitted to Ahsoka. And yet, surprisingly she has no idea about Vader's true identity.
Not that it would matter, because there's no way for her to turn her Master to Light Side of the Force balance. She could as well know and I think she knows who Vader truly is and that pain might keep her hiding the matter, because she's so shamed that it was her Master following order 66 down to letter. Yet, I think she should come out and use the knowledge to hurt the empire.
What was also interesting was the notion from Emperor himself when he revealed that there are quite a number Jedi's in hiding. I don't he meant Ashoka, Esra, Kanan, Kenobi or Yoda but the other ones of those ten thousand that had scattered all over the galaxy. It's a big place after all - even with advances like FTL travel. Also what's interesting is that Ahsoka still doesn't claim that she's one but rather she stays on side, almost like the third party, making her more like one of Grey's - neutral force users.
The term
Gray Jedi, or
Gray, had two meanings. First, it was used by
Jedi and
Sith to describe
Force-users who walked the line between the
light and
dark sides of
the Force without surrendering to the dark side, and second, it described Jedi who distanced themselves from the
Jedi High Council and operated outside the strictures of the
Jedi Code. However, those who were considered to be
true Gray Jedi met both qualifications and did not belong to any particular Force tradition.

Before this episode Grey's have never been mentioned in the canon. They have only been part of the Expanded Universe, but yet I cannot think about Ahsoka's departure from Jedi Order any other way than her standing in the middle ground, undecided to follow neither Sith or Jedi. What that means in the long run is a good question. But I acknowledge that in the long run it would be better for Ezra to learn from both schools, and use that knowledge to carve his way in the universe that is now mostly dominated by the Dark Side.
PS. It seems I was right. Inquisitors are Emperor's sith warriors.
