Man, it is so nice to see a happy and healthy Marcy again. The whole episode felt different in tone after the stew. Here's hoping that our intrepid group can proceed a bit smoother from here. If I remember correctly, they are just ~2 days away from where the dragon is. However, the anime viewer me knows that we are simply on episode 9/24, so there is a lot of story left to go.
Earlier today, I read through the latest production notes entry from Sakugablog about this series and I think it applies to this episode a lot. The basic premise was that Trigger has been smart and deliberate about what episodes/sequences they invest time/money into. This episode is one in which they could stay relatively restrained in their animation, and instead rely on the incredible voice talent to convey a lot of the emotion instead. Things like the barely concealed hostility in Marcy's and Namari's voices when they reunite for the first time make it obvious how they are feeling.
Speaking of Namari, her death really shocked me. It came out of nowhere so suddenly. I think that helped get across just how casually death is often perceived by adventurers in the dungeon. It was fortunate that there was somebody in the group that could heal Marcille though. So, you might have been a bit of a dick gnome-dude, but you were a bro when it counted.
Finally, I was happy to see some of the magical genius side of Marcille this episode. I get the impression that coming up with the idea of cooking/eating spirits to regain magic is not a standard thing that is done. So, she managed to connect several magical knowledge dots together to come up with a solution that allowed her to continue their quest. I work professionally in the sciences and this is what innovation looks like. Often, all the principles have existed for a while, it just needs the right connections to be drawn between them for a new discovery to be made and put to use.
