A detail I really like is how much taller and broader that Falin is compared to Marcille. An actual emphasis on the Tall Man race being legitimately taller than the other races, it's not just Laios being tall because he's their bulky fighter.
Falin isn't a mage though, she's a cleric (different magic heritage going on here). Heavily implied that she uses the same magic that gnomes do, since she teleported the entire party in the first episode, and the old gnome that Namari is working for now also has gateway paintings set up to transit between the middle levels and his base of operations on the surface.
But given Falin's power boost, even before they ate and considering she should have been basically drained completely like Marcille was a few episodes ago, something is definitely off with the method they used to revive her and the means they took to accomplish it. She shouldn't be flush with magic, and they all noticed it.
Marcille said they usually use lambs or goats when they have to pull someone back without a mostly intact dead body. Those are surface animals. Marcille just used a dungeon monster imbued with magic, on account of it being a dragon.
