Yeah.
Celebrendes and the Dwarves collaborate on more applications of electricity. They can't get anywhere with computers but they think they know the materials they'd need. She goes out and looks at the Silmaril and feels no impulse to snatch it out of the sky. She swears unimportant things and checks that it doesn't feel like anything. It doesn't.
She catalogues her brain. She can't do it on paper or out loud, the Enemy might be listening; she sings, sometimes, when Annie is behind a few stone walls, or listens to Lírnith sing which she can do even while holding Annie because Elf hearing is better than human. She tries to follow what the engineers are doing, tries to establish for herself whether Annie really does have to be from a different world. She can't. Electricity could too easily be made up, the results to their experiments could too easily be made up, it would require the Enemy have a creative mind but, well, she does.
She catalogues her brain thoroughly enough that if everything goes exactly as she is expecting it to she won't have a panic attack. She won't enjoy it, it'll be an odd sort of pantomime with the steps falling into place in the grooves in her brain she prepared for them, but she won't have a panic attack. She bounces up to Annie and says she had a breakthrough at coping with things and wants to kiss her more, and she does, and she doesn't cry or have a panic attack and Annie looks happy, which is the most important thing in the world.
