@braydin-hawlette good solutions. Even if for right now there is no plan to publish and it is just up on your website -- if it's a portfolio piece, you may still want to make sure that what you show is accurate.
Wow, it sounds like there is A LOT of backstory and worldbuilding that we don't see in this chapter! That's awesome! Is there a way to include some of those salient character points in the excerpt? In my opinion, it would be helpful to know that Tienna can hear but doesn't speak. Does that add to the story? If not, if you want the focus to stay on the brothers, then it might be clearer for the reader to have Tienna say nothing (i.e. no signing) in this chapter -- leave that for later.
And yes, of course you can pick my brain and ask any questions. Happy to share what I know!
