(1) While I like how Weiss is turning out for the better, when...did she start jumping on chairs and acting like a complete doofus? Don't get me wrong, it's great to see her like that, and I'm sure she's doing it to be "the best teammate." But...what happened to the serious Weiss? When did she start acting like Ruby? This is the problem with the character development. You can't just slap new characterization and go, "Oh, she developed over the timeskip." You mean the 2-4 week timeskip?
(2) And meanwhile…2 CHARACTER ARCS FOR YOU, JAUNE ARC! YOU GO, JAUNE ARC! *coughnotreallycough*
This is an issue I have talked about a few times. Team bonding is not shown on screen, the characters all just act in a way that is supposed to imply how close they have gotten. Weiss acting like Ruby now because how often they are together, Weiss caring about Blake and not letting her run off, Weiss and Yang took over planning an entire dance and didn’t have a single serious fight. Clearly they are all closer and little miss loneliest of all isn’t so alone anymore.
It’s great and I’m happy, but I would have loved to see them getting closer, to have on screen development. It is very lazy to have characters acting seemingly ooc an then go “oh well time passed and they changed!” Weiss in particular did almost a complete 180 on how we knew her.
