When he meets with Victor Frankenstein, the creature relates what has happened to him since his beginning. After this, he demands that Victor create a companion for him.
Tortured by the knowledge that he is the "true murderer of William and Justine," Victor Frankenstein returns to nature for a sublime experience of the feeling of awe, hope, and ecstasy in the valley of Chamounix. However, it is there that he re-encounters his creature.
Victor tells his creature that he wishes that the extinction of the creature's life would restore the victims who were so "diabolically murdered!" The creature replies that he expected such a brutal reception. He adds,
How dare you sport thus with life? Do your duty towards me, and I will do mine towards you and the rest of mankind (Chapter 10).
The creature offers to leave Victor and his friends and family alone if he will comply with his conditions. If Victor refuses, however, the creature vows,
I will work at your destruction, nor finish until I desolate your heart, so that you shall curse the hour of your birth (Chapter 17).
Furthermore, the creature promises to be "mild and docile to my natural lord and king" if Victor will do his part, a part that Victor owes him. He tells Victor that he should be his Adam, but he is, instead, the "fallen angel" who has been driven away from joy. He argues that he was once kind and good; however, misery caused him to become a fiend. If Victor will make him happy, he will again be virtuous.
I was benevolent; my soul glowed with love and humanity: but I am not alone, miserably alone? You, my creator, abhor me; what hope can I gather from your fellow-creatures, who owe me nothing? (Chapter 10)
The creature relates what has happened to him since his abandonment, describing his time living in the hovel behind the cottage of the DeLaceys. He also describes the gratuitous cruelty of the DeLaceys when they believed he was harming their father, and the attack upon him when he saves a girl from drowning. This cruelty affects the creature profoundly, and he avenges himself upon the Frankenstein family by killing William and implicating Justine.
The creature then offers his ultimatum, and Victor listens because he feels that as the creator, he has some duty to the creature before he "complains of his wickedness." The creature tells Victor:
You must create a female for me with whom I can live in the interchange of those sympathies necessary for my being (Chapter 17).
The creature sees having a companion who is like him as his only chance for contentment; she would not reject him as mankind seems to have done. He demands that Victor create a female in his likeness for him. Victor realizes the consequences of this creation, but he also realizes that the creature can relate to no one but another creature like him. He promises Victor that if he creates a woman for him, no other human being will ever see him again.
The creature tells Victor the story of how he had spent time observing the family from a cave near a cottage. He told Victor how he had wanted to be a part of humanity. He had read books which he had taught himself how to read. He had seen the beauty of humanity in the books and had become lonely and in need of human interaction in order to live.
He had made his presence known to the blind man, begging him to save him from his life of loneliness. When the man's family saw him they had shunned him, screamed, and fainted. For the creature it was a turning point. He knew he would never be a man like other men but rather something despised and hunted. Enraged he had become a killing machine by destroying humans. He would never feel a mother's love or the wanting touch of a human.
The creature demands that Victor create him a female like him. He wants Victor to make her from parts the same way he has been formed. He wants to live with her and promises Victor that he will take her far away from society and live alone with her. Victor tells him that he can not bring himself to create another creature.
