Everything Wrong with RWBY Part 6 (Show, don't Tell)

A Philosophy of Showing Rather than Telling Which Does Not Always Require Flashbacks, Expenses, Etc.
This would be a suggestion/hope I have for RWBY's writing decisions in the future. It has to do with a core complaint of the series, which was also adressed by the showrunners' most recent AMA here:
Three things that we think we can improve on: 1) More fights that better utilize characters' weapons and abilities. 2) More attention and meaningful conflicts for Ruby 3) Show don't tell.
The adage of "show don't tell" is something I'm sure most people are familiar with, and it gets thrown around here a lot for mainly legitimate reasons.
But I was hoping that this thread could be a place for RWBY's audience to bring up examples from the show where we were "told" something, and instead suggest ways in which it could have been "shown".
A common suggestion is to, instead of having scenes where a person talks about things that happened in their past, actually go back and show those events happening. This sort of criticism has been levvied repeatedly against Blake-scenes in Menagerie, and for the most part I agree with the stance.
But I wanted to bring up the idea that showing rather than telling doesn't always necessitate things like flashbacks, which are an additional expense for the production. Sometimes just simple structuring of dialogue can change a lot.
Example of "telling":
This line, which I consider one of the most blatant offenders of volume 5.
Ren: A common philosophy is that a warrior’s Semblance is a part of who they are. Some say your personality and character can define your Semblance while some claim that it is the other way around. Of course, there are still many who don’t see a connection at all.
First of all, it's fairly meaningless exposition. "Semblance is either influenced by your personality, influences your personality, or there is no connection between your semblance and personality." Very informative.
The only tidbit we actually learn from that whole segment is that there is disagreement in society regarding how semblances operate. But it's shoveled in our face without much character or relevance.
Suggestion for "showing":
Pretty simple change really, if there is general academic disagreement on the topic, have some of the characters believe in different stances and disagree with each other. That way this brief exchange becomes about enriching the characters by giving them opinions. I.e something like:

• I believe X originates from this.

• Nah, my parents told me it was the other way around.

• You're both being superstitious, there's no proven connection at all!

• Long story short, nobody knows for sure.

Exactly the same outcome, except it lets us convey the information in a way that melds more characterization with its exposition.
That was just a minor example, what are your thoughts on the subject? What suggestions do you have for writers in general that can faciliate showing rather than telling?
I think "Show don't tell" has been an issue for a while, but I think the bigger problem was so much of the dialog didn't even tell. Arguably the worst culprit was the "this person is the embodiment of this word" speech. The biggest questions you should ask (apart from asking if this is how humans talk lol) was did it give new information or did it progress the plot? You can ignore these questions if a scene is meant to be comedic or provide another effect, but this is not the case in this scene. Ultimately the entirety of the dialog could be removed with no effect on the story. The next scene (man not a great episode) we get the Ruby speech on how she is upset about Penny and Pyrrha. Now getting Oscar's emotions is definitely a show don't tell moment, but Ruby's speech is just her reiterating her character's motivation. It is overly long without adding anything which becomes all the more frustrating as dialog on key plot points with Ozpin (silver eyes, Pyrrha, etc.) are ignored.
That's a fair point, and I honestly don't think that exchange about where semblances come from was necessary in the first place, since it was so lackluster in terms of revelations. But I disagree with your claim that the characters having different beliefs/opinions on where semblances come from would add nothing to their characters.
Having debates and disagreements about subjects big and small is a part of being human, and I think it'd be more convincing worldbuilding to make it so that all of these young huntsment/huntresses who spent years with superpowers (or around people with superpowers) would have some sort of stance, belief or opinion regarding that phenomenon.
You could ask a group of your friends whether they think there is life on other planets, and them disagreeing with one another wouldn't be weird, but it would be strange if one of your friends walked up to the group and said "some people believe there is life on other planets, others do not believe there is life on other planets, and some people believe it's impossible to know either way." That doesn't make them seem more knowledgeable about the world, it just seems like an exchange real people wouldn't have. Do you see what I'm getting at?
