Warning: Full spoilers for the episode below. Just a quick note to start things off - Disney XD aired both parts of the Star Wars Rebels Season 4 premiere tonight. Eric Goldman already reviewed "Heroes of Mandalore Part 1" when it was screened at Star Wars Celebration earlier this year, so tonight I'll just be focusing on Part 2. For whatever flaws it may have, Star Wars Rebels has been great about tying up the many loose ends left over from Clone Wars.
