Towards the end of the story, what does the speaker want the raven to do in the short story "The Raven," by Edgar Allan Poe?

On the fast track to madness due to the loss of his lover Lenore, the speaker in Edgar Allan Poe's poem "The Raven" would like nothing more than for the raven to give him good news about her return. When he asks the bird if he and Lenore will be reunited in Heaven, it accordingly responds "Nevermore!" Unhappy at the response, the reader demands that the raven leave him alone and get back to the "Plutonian shore" (return to the Devil). However, the bird refuses to leave, again remarking "Nevermore!" and continues "still sitting" on its perch on the bust of Pallas above the chamber door.
