That is a very cute smile.
(Although — I'm a bit frustrated by it, I guess. Look, Rina has a legit disability. I get that the joke of this is that she's really smiling and the new Board is just revealing that — but it feels more likely that she's just gotten the photorealistic render of her face to make the expressions she wishes she could make. Maybe I'm over-identifying. But saying "hey, I want you to forego using this technology that makes your life better because you're cuter without it" is just super-ableist.)
