We return to the present time, when Tomas and Tereza are together again in Prague.
Tereza wakes up in the middle of the night and realizes that she is now responsible for Tomas, because he came back to Prague for her. She's not sure she has to strength to shoulder this responsibility.
But then she remembers the fortuities on the day they met. Her sense of beauty cures her depression and "imbue[s] her with a new will to live" (2.29.5).
