Raskolnikov had been very dreamy for a few days before. He asked a great deal about his mother and was constantly anxious about her. He worried so much about her that it alarmed Dounia. When he heard about his mother’s illness he became very gloomy. With Sonia he was particularly reserved all the time. With the help of the money left to her by Svidrigaïlov, Sonia had long ago made her preparations to follow the party of convicts in which he was despatched to Siberia. Not a word passed between Raskolnikov and her on the subject, but both knew it would be so. At the final leave-taking he smiled strangely at his sister’s and Razumihin’s fervent anticipations of their happy future together when he should come out of prison. He predicted that their mother’s illness would soon have a fatal ending. Sonia and he at last set off.
