I'm glad the show is getting another season. I hope Naare makes a return, but it doesn't look like she will. Graballa's role I'm gonna guess would be an indication of Jabba being dead since the link describes the Hutts being desperate. Hera from Star Wars Rebels being in the next season might mean that the rest of her crew might make some appearances as well. Most likely cameos.
I find it interesting how Grey DeLisle Griffin voiced Dorothy in the Tom And Jerry/Wizard Of Oz movies given that she would voice both The Good Witch and The Bad Witch in the Boomerang cartoon Dorothy And The Wizard Of Oz, and also voiced Dorothy's mother in the Amazon cartoon Lost In Oz.
