Well folks, I'm sorry to say this, but I'm pretty sure that Barriss Offee is the Jedi behind the attacks on the temple, and the disenfranchising of Ahsoka. When Eric Goldman from IGN proposed that idea, I didn't believe it at first, but all the evidence points towards that direction. We got to see more of that 1313 videogame scenario, and part of the Coruscant underworld, which is meant to be seen more in the upcoming Star Wars live action series in a few years. We also got to see how much further redeemed Asajj Ventress is at this point, and the alliance she had with Ahsoka was quite interesting. Mace Windu has been doubting on Anakin's ability from this time period, which will later turn out to be a catalyst in Anakin's fall to the dark side.
Anakin and Plo Koon managed to capture Ahsoka in the end, and the next and final episode of Season 5 pinpoints towards the fact that we will see the trial Ahsoka will apparently be on. I wish to see how all of this is connected with the Sith Grand Plan, and see more questions answered on the next episode.
