The argument between Anna and Karenin has marked a change in their relationship. Anna spends more and more time with Princess Betsy and Vronsky. Karenin feels powerless but cannot speak seriously to Anna.
After the argument, there is a wall between Anna and Karenin: she continues to see Vronsky everywhere, but Karenin cannot express his feelings to her.
The chapter ends with two lines of ellipses, marking a large break between what has come before and what happens next.
Even though Anna Karenina is full of words and dialogue, many of the most important changes and messages occur in nonverbal moments.
