I have been watching Star Wars Rebels lately, while pondering possible avenues of development. I am not going to sugar coat anything, but I am not going to hold back spoilers if anyone hasn't seen the show up to date.
I have read a lot of speculation on the identity of 'Fulcrum', with a lot of people guessing the mysterious contact is in fact Ashoka Tano. Does make a bit of sense, setting up for more connections to the Clone Wars. I can see it.
Following that line of speculation, I would further guess that the Inquisitor has a boss between him and Vader and/or Sidious. My money's on Bariss Offee as the High Inquisitor. Her fate was up in the air at the end of the Clone Wars series, and she could easily have joined the Empire hunting Jedi as High Inquisitor, and while not a Sith, she would be able to train others as Dark Jedi.
Which leads me to the latest SW:R episode "Call to Arms". In walks Grand Moff Tarkin, proving he is no slouch by laying down the law(and heads), setting successful traps, and generally drinking everyone's milkshake. So we have Kanan in the hands of the Empire, and the intrepid heroes planning a rescue attempt to retrieve him. Next ep premieres on the 23rd...
I would guess that Ashoka shows up to spring Kanan, curbstompts the Inquisitor, faces off against Tarkin once again, only to have Bariss show up. Bariss and Ashoka duel, Ashoka gets critically injured and forced into carbonite to save her life. She is hidden until she can heal as Bariss steps in as the bad guy pursuing the Rebels.
Of course, speculation, but could be a way to have Ashoka show up in the new Star Wars films...also a way to bridge all of the series together with the movies.
Just the musing at 1am on a Wednesday....
