Asohka looks like she pretty much embraced the fact that she no longer is a Jedi with those grey lightsabers! Kanan seems closer to the orders tradition and he attempts to train Ezra in its dogma.
Palpatine easily overpowered any Jedi since he weakened their ability in the force. Yoda realizes this and flees, because he really is no match for the emperor at this point. Mace Windu almost beating Palpatine also doesn't make much sense. Sure, Mace possibly hasn't lost as much of his connection with the force as a result of being capable of utilizing some dark side powers without falling to it, but i think it is more likely that Palpatine put on a show to make Anakin commit to his cause.
