Well, think about it. We're going to a small grove owned by Eily, in order to pick flowers. That is, from our perspective, what is happening. Nothing out of the ordinary.
From the perspective of almost literally every being that exists, a nightmare-being of the endless void is travelling to a weak point in reality, a place bordering on faerie, in order to exploit that weakness. Yes, we'll be using it for tea, but is that—think about this for a second—is that something you'd call plausible? Or is this the sort of thing that any magical girl, self-declared guardian of the world, should be opposing if at all possible? A ruinous power of the void, nearing the end of a plan stretching entire... uh, minutes?
It's somewhere nearly impossible to reach. Would anyone truly go there for tea?
...I mean, yes. We would. But the megucas don't know that.
The thing that is most entertaining about writing Eily is that -
She is so far in her own head, so caught up in her own thoughts, and so completely lacking in perception and native empathy that she not only fails to notice things like the
blatant magical girl; it also just never occurs to her to really, genuinely think about how she is perceived by most people.
So, like, to expand on what Baughn's saying -
To the petty gods and defenders of Creation, Eily is
not a pathetic, adorably useless disaster.
She is a
terrifying agent of destruction; an unstoppable engine of death and bleak endings; who has only ever been
delayed before at tremendous cost; and who has -
for unclear reasons - just ... rather abruptly stopped destroying things.
Maybe it's because she's decided to stop pursuing the end of all things. It's, you know,
conceivable. It
could happen, theoretically.
Or maybe she's just putting a new, more subtle plan into motion.
Maybe it just
looks like she's no longer destroying things because the plot she's weaving is, actually, genuinely, just that subtle.
Do you really want to take that chance?
Because she
has been cunning and careful and subtle, before. She
has put these long, complex, and incredibly well-hidden plots into motion before. She
has blindsided the defenders of the world before, torn whole concepts screaming out of the fabric of reality before the petty gods of Creation had any idea those concepts were even under threat.
Maybe it might be best to keep a close watch on her, just in case.
EDIT
Also I am shilling for Midnight Bubble as my preferred variant.
Midnight Bubble is obviously Evening Glitter's initially-villainous-rival-who-after-being-beaten-and-shown-the-magic-of-togetherness-goes-on-to-be-Evening-Glitter's-devoted-student-and-then-a-powerful-force-for-togetherness-in-her-own-right.
The, let's say ... second one of those, because that happens multiple times in
Pastel Pony Princesses.
