Many of the events featured in this episode were hinted at the Star Wars Rebels trailer released during Star Wars Celebration Europe.
There is a lot of action and some intense moments. Two fan favorites from Star Wars: The Clone Wars get ample screen time in this episode, and the new threat revealed at Star Wars Celebration is called in, to deal with the Rebels.
It's not clear how much time has passed, since the events of the season two finale. Ezra has grown into a leader and is reminiscent of Anakin in many ways. Kanan has gone through some changes as well, and he learns a few new things about himself and the force.
