After a beautiful (if somewhat hard-to-swallow) explanation of how the gem people came to be, we see that gaining crystalline form hasn’t changed the fact that people still procrastinate and whine, as Phos does for most of this episode.
They’ve assigned themselves the role of finding another role for their new friend Cinnabar, but ends up making zero progress with the encyclopedia Kongou instructed her to compile.
After getting no love from Jade, Phos goes out to meet Diamond, who is on patrol. Diamond is very pretty and ethereal to behold with their irridescent features and gentle Kayano Ai voice.
But Dia doesn’t have much to tell Phos either; Phos may look up to Dia, but Dia wallows in the shadow of the just-as-hard but also tougher Bort, who swoops in to save both Phos and Dia when there’s a Lunarian attack.
Bort also exposes Diamond’s hidden missing hand, making Dia a liability in the field. Then another Lunarian cloud appears, but it passes right over the three gems and heads to HQ, where it dumps a giant shell at colonnade.
The Lunarians are dealt with by Bort, Dia and Jade, but while they are, a snail emerges from the shell and slurps up Phos, who instantly starts to melt and dissolve in the snail’s digestive juices. Phos’ impudence may be grating, and I assume they won’t die from this, but their rapid dissolution was still graphic and upsetting. They seem to be a magnet for trouble.
One thing’s for certain: this snail looks like just the kind of threat Cinnabar could deal with when no one else can, due to their corrosive poison. I realize Cinnabar is stationed pretty far off, but their complete absence from this episode was nevertheless conspicuous.
