What happens after Frankenstein's creation comes to life?

On a chill night of November, Victor finally brings his creation to life. Upon the opening of the creature's "dull yellow eye," Victor feels violently ill, as though he has witnessed a great catastrophe. Though he had selected the creature's parts because he considered them beautiful, the finished man is hideous: he has thin black lips, inhuman eyes, and a sallow skin through which one can see the pulsing work of his muscles, arteries, and veins.

The beauty of Frankenstein's dream disappears, and the reality with which he is confronted fills him with horror and disgust. He rushes from the room and returns to his bedchamber. He cannot sleep, plagued as he is by a dream in which he embraces and kisses Elizabeth, only to have her turn to his mother's corpse in his arms.

He awakens late at night to find the creature at his bedside, gazing at him with a fond smile. Though the monster endeavors to speak to him, he leaps out of bed and rushes off into the night. He frantically paces the courtyard for the remainder of the night, and determines to take a restless walk the moment that morning comes.

While walking in town, Frankenstein sees his dear friend Henry Clerval alight from a carriage; overjoyed, he immediately forgets his own misfortunes. Clerval's father has at last permitted him to study at Ingolstadt; the two old friends shall therefore be permanently reunited. Henry tells Victor that his family is wracked with worry since they hear from him so rarely. He exclaims over Frankenstein's unhealthy appearance; Victor, however, refuses to discuss the details of his project.

Victor searches his rooms to make certain that the monster is indeed gone. The next morning, Henry finds him consumed with a hysterical fever. Victor remains bedridden for several months, under the assiduous care of Henry, who determines to conceal the magnitude of Victor's illness from his family. Once Victor can talk coherently, Henry requests that he write a letter, in his own handwriting, to his family at Geneva. There is a letter from Elizabeth that awaits his attention.
