exactly, she basically says a tremendous amount... without having to open her mouth.
i know that there is a lot of talk about how elisabeth's subtleties and micro-expressions are incredible in this show... and they certainly are - she's amazing, but i feel that yvonne at the very least matches her in that department, (and my personal fangirling aside, i believe sometimes she is even better, especially considering that she doesnt have the benefit of an internal monologue to convey anything, and of course the character is incredibly complex and angry and confused.)
that rage scene with the pregnancy is one of my favs as well
... especially when she comes unspooled at the end... "do you understand me" yikes.
another of my favs was a background shot of her where you knew she was wanting to be invited into a meeting at the house and she's standing there and you can tell how dejected she is... that otherwise straight posture gives and the shoulders slump. its a tiny moment that says a lot.
