I've been doing a replay recently and noticed something off about Pyra's powers.

At the end of chapter 3 Pyra gets depowered by Akhos and Obrona's ether trick and needs to wake up Mythra to counter it. But in chapter 2 she wasn't impeded at all by large amounts of water ether because, in her words, "her power doesn't actually come from fire". Then when Mythra pops out and no-sells Obrona's ether block she's said to be using "something else" to fuel herself rather than atmospheric ether.

Now in hindsight both of these special cases are due to P&M using bits and pieces of Pneuma's powers to generate ether internally instead of using atmospheric ether. My question is why then was Pyra affected by Obrona's ether block? Is this a plot hole or am I just missing an important detail?

What's the correct way to talk about someone who has transitioned when referring to them in the past tense? For instance if I'm recounting a story about a trans person but the story occurred prior to their transition is it more appropriate to use their old or new pronouns?
