I just watched the episode. And I gotta say, I can't wait to see more of Salem's other cronies. The grim that Team CDAN (Can't decide a name) fought is interesting. Jaune's new outfit is quite nice, and emotional. I'm also getting a kinda Legend of Korra vibe from it, which I am enjoying. So far so good.
As for the opening, the things shown are interesting to me, particularly the characters. Like the ones shown around Weiss. Or how about those Faunus with Blake, perhaps her family? The Yang segment also gets me wondering, mostly about some wild theories I had at the end of Volume 3.
