Here we have Kanan in season 1. Standing in the forest at night.
This is the season 2 after Kanan is blinded. He's wearing bandages and Maul is in the background. (You can faintly see a soft white glow from Kanan's eyes.)
In this picture, we have Kanan as a blind dragon with Ezra beside him. Behind Kanan is his Master Depa Bilaba as a ghost.
This is done when they get back from Malacore.
