The newest episode of star wars show, showcases the newest clip for Star Wars Rebels. I have taken a moment to watch it (clip starts at 3:39). The show looks awesome but there was no sign of Kanan and it looks like Ezra has a new hair style and lightsaber. I am guessing this takes place later in the season after the dramatic ending to season 2. Let me know what you think about this.
