How does Sasha respond to Olga's smothering in The Darling?

Sasha is embarrassed when Olga tries to follow him to school and tells her to go home and let him walk alone. Olga's life once again has meaning because she lives through Sasha, but Sasha feels smothered by her care and cries out in his sleep words that express his anger toward her and his desire to be free of her smothering love: "I'll give it to you! Get away! Shut up!"
