the unbelievably high amount of emotions that were crammed into that look Carson and Greta exchange after their first kiss
you have Greta’s satisfaction at having been proven right when she correctly guessed Carson’s orientation, the teasing in her eyes, a lot of anticipation of Carson’s reaction now, but also you can tell that she’s holding back a lot, she gave a brief kiss that shattered Carson’s life and now she’s waiting for her to make the next move and she’s putting it all in her hands, and her smile is also addressed directly at Carson, letting her know that this is all okay, that she’s in safe hands, that she’s allowed to want this, that she can have it if only she gives it a chance. and the joy. she looks so, so happy.
meanwhile poor baby girl Carson is going through it, discovering that there’s a reason she’s only just pinpointed why she’s always felt like she didn’t belong, why she’s always felt like her life was a lie, why she ran away from her husband for no reason, that there’s a clear explanation why she felt so drawn to this woman she’d just met and trusted her so instantly, this entire new world is opening to her and it’s so overwhelming. in 1943 she has zero notion of what homosexuality means and suddenly everything clicks into place when that door opens to her all at once.
it’s an extremely intense moment that they executed perfectly and it works so, so well in just a few seconds’ time
