ooo... What's Sol saying to Cinderheart on her and Fallenleaf's journey, if it's not too much to ask? And unsure of the how, but I think it could be neat if he used a blackbird for it - fun nod to her catch in Sign of the Moon(?) & the emotional downswing she had cause of it, might make it a little more unsettling.
I really should keep using blackbirds as symbolism for things that threaten Cinderheart's emotional stability. It would be good form for that to stick around post-Po3 and OotS, thinking about it.
Sol possesses things to speak to Cinderheart. He can't manifest physically at the moment, but when Fallenleaf lapses, he can use certain animals to speak for a short while. The goal here is to hurt Cinderheart somehow, knowing this will weaken Fallenleaf.
So I think his lies should mostly be trying to make rifts between them, knowing a few of her insecurities from waaaay back in Po3
"You're just incidental to her, you know. You're not needed."
"No one really wants you here. You're slowing everyone down."
"Secretly, she haaaates you. She's just tolerating you."
"What a pathetic thing you are! Devoted to someone who's just using you!"
"She could have saved your child, but she didn't. And when you die she won't save you either. Leaving was just a ploy to get away from you, but you ruined it."
"You're less than her. There's a million mortals, but with me in tow? Fallenleaf is a god. What makes you think you deserve this?"
BUT there's a big thing he doesn't know; that she's actively dealt with intrusive thoughts before. What is he, if not an intrusive thought externalized?
"I WISH my own thoughts had snappable necks!!" She jokes to Fallenleaf one day, Sol's little chesspiece of a blackbird dead and plucked and going in the stew. Fallenleaf's gaze settles on something a thousand yards away. There's a long pause, quiet enough that the birdsong in the distance is deafening.
"...To you, it-talks? You, are being hunted?"
Use the moment to show that even though CINDERHEART is equipped to handle this exact type of mind-fuckery on Sol's behalf, Fallenleaf is not. And the fact that he's targeting her lover to try and hurt his real quarry is terrifying, sickening, and painful to Fallenleaf.
Her choice to associate with this being, to let him into her chest, has no end. She's chained to a monster, and Sol won't just stop at hurting Fallenleaf to get his freedom.
The fact that it's Cinderheart's story could also really work in its favor, since we won't have a large window into Fallen's head to know exactly how she herself is dealing with this. Or how much Sol ACTUALLY knows about Fallenleaf, and how he doesn't actually have any insight to her thoughts or feelings.
