Jennifer was one of the Others who attacked the tail survivors camp for a second time on day 12. She tackled Ana Lucia when she tried to stop the Others from taking Zack and Emma, but Ana Lucia then struck her with a rock and killing her. After her death, Ana Lucia found a list with the names of the survivors they kidnapped, and a U.S. Army knife in her pocket.
Jennifer's name was mentioned by Ben during a conversation with Ana Lucia in the original script of "Two for the Road". However, the scene was deleted in the episode.
