I was rewatching Furious Fu in preparation for Ephemeral, and then I thought "hmm I should probably rewatch that knight episode since they're referencing it so blatantly here." It's not an episode I rewatch much outside of bingeing the whole series, so there was a lot I forgot about (like that it's called Darkblade oops). I'm gonna use this post to talk about things that stood out to me, potentially important for Su-Han's return in Ephemeral, potentially important for later.
The episode starts off with this interesting exchange that's immediately ringing alarm bells for me:
Marinette: And yet again, Marinette hopes she'll finally have enough time to complete her magic box.
Tikki: What's the magic box for, Marinette?
Marinette: To lock up my diary and all my secrets.
Tikki: Every little secret? You're telling me you write everything down in that thing?
Marinette: Uh yeah, something wrong?
Tikki: Well, for one: what if someone finds out you're Ladybug? And two: what if someone finds out you're Ladybug!?!
Magic boxes? Ladybug's identity revealed? I am already concerned, but especially when considering the callback to the diary we got in Truth at the beginning of Season 4.
Then we have the sheer bizarreness that is Adrien's fencing instructor running for Mayor of Paris? That part's weird, but the lore it brings up is interesting. D'Argencourt's a descendant of a black knight called Darkblade, and that's definitely supposed to be a former black cat miraculous holder, right? That's my immediate guess anyway.
This could be significant to the upcoming conflict between the Order of the Guardians and Chat Noir. The Ephemeral synopsis mentions Su-Han's insistence that the black holder must be known, so they can be controlled, which also aligns with what he said in Furious Fu. "Some jewels missing and Plagg roaming free? The end of dinosaurs and dragons, doesn't that alarm anyone?"
Wait dragons?
Huh. D'Argencourt's crest sure looks like a dragon.
Here is my mini-theory on what this means. Darkblade was a black cat holder that went rogue and used his powers to subjugate his people (even in D'Argencourt's biased positve account it's said he "ruled with an iron fist" so probably not a good person). This is somehow related to him causing dragons in medieval europe to go extinct. The fact that he was able to do this may even be how he was able to conquer Paris in the first place if dragons were a such huge danger to people that he eliminated. This would be why Su-Han is so concerned with making sure the black cat miraculous is with a holder that he can keep an eye on, to prevent anything like this from happening again.
Also worth noting that this is one of the few episodes where Chat Noir is fighting the akuma by himself for a significant portion of the episode, and this leads to lots of shots of him fencing with D'Argencourt in a way that emphasizes their similarities and differences.
