I don't have a link to the next episode, but from what I've heard, it's just as bad as I thought it'd be.
They seriously killed off Penny AGAIN just to give Winter the Maiden powers, which she used to kill Ironwood. It's almost like a metaphor for the show writing off the only two characters most people actually care about. Winter even says it's Ironwood's fault everything's gone to hell.
Also, according to TV Tropes, before the episode even began, they put up the number for the National Suicide Prevention Hotline because of what Penny does. If you have to consider putting that disclaimer before your show, maybe you should rethink a few of your writing decisions.
The Stretchy Dude I don't care about sacrifices himself to stop the bomb while Not-Nora finally helps Qrow talk Harriet out of committing genocide.
Cinder uses the Creation Relic Genie to cause Atlas to crash into Mantle, killing Watts in the process, because that would imply she actually had character development. We never learn what happened to Maria, Pietro, Team FNKI, Marrow, or the Schnee Family, because RWBY has way too many characters.
And obviously the rest of Team RWBY is knocked into the void, along with Jaune and Neo for some reason, and like everyone predicted, next season's going to be an Alice in Wonderland homage. Yay...
