What I am really liking about this episode, and it is sort of emblematic of the series so far, is how far Ruri seems to have matured. I begin to wonder how Ruri from episode 1 would see herself now, or vice versa. We see the evolution in kit of course, but honestly when she gets excited now, it's out of fascination. I get that Ruri sometimes slides back into that immature slide, but from my impressions, her character arc is that discovering minerology has helped her mature much faster than before.

No better example than when she realizes the mistake in her research and fesses up right away after checking her own work. The typical trope in a lesser show would have had her go into denial or hide the truth, but it was really nice to see her come forward about it.

Really hope Ruri gets a second-author slot on whatever paper writes on this discovery.

I would be amazed if they even made her write a portion of it...and only because I am waiting for this series to depict the tedium of writing up research papers.

Sapphires are so pretty and to see a whole bunch laid out would be pretty cool to see like that

Ruri has evolved a lot in terms of knowledge: she is now able to come up with really good ideas. She has found her vocation. All her efforts were rewarded. Although she made a mistake in her notes, she was able to detect and correct it on her own.

It was a beautiful episode.

There's a lot of philosophy of science here.

It tackles myths versus naturalistic explanations without necessarily condemning the myths.

It's a great episode when you think about it.

Anticlimatic, I was wondering what they would do once they found the sapphire..

Behold of my awesomeness~

Seems the sapphires have finally been found. was really interesting to see the scientific process behind hunting them down, and the fact that there were mistakes along the way made it even better. Interesting that the story about the dragon tied into this as well, that's really cool.

Amazing episode. Very educational. Makes you want to explore rivers and mountains to find the source location. Not a common knowledge for sure.

That was such a great episode! The pay off was amazing. Ruri's and teams efforts really did pay in the form of Sapphires. Saphhire's one of my fav gems. I learnt about them from Pokemon I think xD. The fusion of ancient mythology and modern understanding was incredible. I never thought of that. The point about how myths and stories shouldnt be discarded but understood from a modern perspective really makes you ponder. Ruri realized her error they were quickly able to narrow down their search. The teams really supportive for sure. All in all it was such a great end to the first half. The animation and direction was god tier as usual. Loved the part with the research to be continued. Those captions were great too. Reminded me of early fan subs.

Well, Ruri might not always look like it but she worked hard this episode. She's also surprisingly attentive to details.

I was kinda surprised she has a sapphire book but that's how much she loves her work.
Nagi is such a great senpai.

Ruri is really learning a lot about scientific work, she is just in high school in the story, right?

The notebook ending "to be continued" would be a perfect way to end the season!

Wow, they moved from a few tiny sapphire fragments to some quite large crystals!
