Nikki flirts with Dr. Arzt so that he will draw her a map to where the diamonds might be. She learns a little about the bugs he is collecting.
Paulo worries that the diamonds are tearing their relationship apart, so when he finds them, he doesn't tell Nikki. He starts to bury them on the beach, but instead takes them to The Pearl Station that he and Nikki had found earlier. He hides them in the toilet, but while there overhears a conversation between Juliet and Ben about getting Jack to do the surgery.
Nikki finds out that Paulo has the diamonds and uses one of Arzt's spiders to paralyze Paulo. She is also bitten by a spider and tries to hurry and bury the diamonds before falling in the sand in front of Hurley and Sawyer, who assume she is dead.
The survivors dig a grave and bury Nikki and Paulo alive.
