ah, yeah makes sense! I think since im still very early in the book, i'm not seeing the extent of the scandal of it all quite yet, but i can't help but think that the fact that for the anna/vronsky side of it is because a) they are yet to admit it to themselves, b) the author describes a lot of body actions (like blushing) in order to show a truth that speech may not, and c) it contrasts dramatically with levin's proposal and feelings to kitty.

for dolly and oblonsky, i think it's partly because there isn't a reconciliation, not really. oblonsky hasn't changed and it's likely (im assuming, bc im still, like, 10% into this book) dolly has just remembered they have, like, five children, and there would be a social scandal which is also important given kitty is trying to get married. it also seems that not having a scene in fits oblonsky's thinking/philosophy to just let things happen if he doesn't know what to do because it will all fix itself. he isn't ready to go on some moral journey (yet?). and, of course, this centres the conversation on key character traits of anna and will likely set up a contrast between oblonsky/dolly and anna/vronsky!!
