For a while Jekyll enjoys his two bodies; he can do whatever he likes without fear of discovery. His pleasure is stunted when Hyde kills Carew in a nonsensical fit, and he resolves never to take the potion again. Hyde is now strong, however, and emerges whether Jekyll will have him or not. Indeed, Jekyll must use the potion to be rid of him if only for a moment. Jekyll knows that it is only by killing his body that Hyde’s body, too, will die.
