Beloved has an unnerving obsession with Sethe. When Denver tells Beloved not to let Sethe know who she (Beloved) actually is, Beloved has a complete shift of character.
She says, "Don't tell me what to do. Don't you never never tell me what to do."
Denver says, "But I'm on your side, Beloved."
Beloved says, "She is the one. She is the one I need. You can go but she is the one I have to have."
Clearly, in this scene, Denver is proclaiming her allegiance to Beloved over her mother, yet Beloved is does not care. She possess one single desire, and will cast aside anything, and anyone that gets in her way of getting Sethe. Creepy.
What do you think Beloved means when she says, "She is the one I need...have to have"? Why does she need Sethe? Is it vengeance? love? ...?
