She—
(closes her eyes so she'll stop thinking about how much she wants that poor stranger to fuck her)
—thinks.
It's not erased, not forgotten, it's—obfuscated. Blocked. She can see it but she can't... think it?
Well, which words match the ones she can't quite think?
Piece by piece, she fits a sentence together. Weak and strong are in there, and but, and I—no, I am—and—enough? Weak, but strong enough? That scans. That sounds like a way her soul might choose to describe her.
There's another clause, though, and that one's slipperier. She chases it around in circles for what feels like an hour before she finally figures out that it rhymes.
Brief, but long enough; weak, but strong enough...
But when she tries to say it, say it properly, she can't. That's blocked too.
She snarls very quietly and tries again. Repeats it over and over in her head, murmurs the phrases quietly without the force of a true incantation, tries to get the rhythm of it installed so deeply in her muscle memory that her voice will say the words without her having to think about it at all.
Brief, but long enough; weak, but strong enough; I am Hollow Witch Scintilla!
Does she even have all the right words? It's hard to know for sure. But as best she could determine, checking and double-checking, all the words are there and in the right order. It's the best she's got.
