Describe the discussion between Bella and Jacob when they return to the beach.

Jacob takes Bella to the beach again, and they talk about the child with whom another werewolf recently imprinted. Jacob says he has not imprinted yet, but he has not seen much of the world. Jacob then insists that he does not want to see more of the world if it will take him from Bella. However, when Bella tells Jacob that she plans to become a vampire after her high school graduation, Jacob becomes very angry and they argue.
