Hey i found a picture of Jaune in Volume 20 !

"They clearly state that the loss of Pyrrha is going to have a huge effect on Jaune’s character and personality, and that he’ll never likely be the same positive, clumsy goofball we’ve known for years."

So we're going to get a Guts moment where he spots Cinder and goes on a blind rage? Possibly see him become a badass? Yes please. I do hope he retains some of his traits though. Full blown revenge lust is fun, but at the cost of his personality is a little much.
