Something tells me Phos is not going to be able to destroy the earth gems, at least not on this trip. They are barely together, and they still can’t think cohesively. Padparadscha is also not with them this time, which is not good because Padpa was kind of the last reliable source Phos has had in their moon state.
Dia. They were acting like they’ve completely moved on from the past, talking about shows and rehearsals, things that they are putting their talent into. Being an idol has made them forget about the fact that they could never measure up to Bortz back on Earth, which they were happier with, at least it seems like it. And Phos of course, OF COURSE, has to bring up the fact that they will kill bortz. This not only reminds Dia of the unhappiness they’ve kept buried for so long, but basically gives Dia permission to become hostile. Will Dia ever act for themselves, based on their own emotions, and not just be pursaded based on what others do and say. We may never know the answer. I honestly feel just as sorry for Dia as I do for Phos in this scene.
