Stepan finishes translating Tatiana's diary, Anna learns that Semyon raped Tatiana after Kirill failed to do so, explaining that he would show Kirill how to "break" her. The diary also states that Semyon gave her pills to induce an abortion, and Anna realizes that the baby was fathered by Semyon. Meanwhile, Semyon realizes that Anna knows the truth about the baby and visits her at the hospital.
