...first time we've seen Vader's helmet cut open on screen.
In Star Wars Rebels, Ahsoka Tano gives Vader a similar helmet gash. Rebels is an excellent series.
Thought the season finale was pretty good. Kenobi Vs Vader was cool. Reva's story arc was underwhelming and her inclusion unnecessary. Would much rather have seen her as a committed Inquisitor, with a Starscream-esque backstabby/bootlick persona. The whole presence of the Inquisitors felt meh, and I really don't understand how and why Reva's motivations/ survival/ etc, got the green light.
