later in the season, well...by the fourth episode, actually....we meet the tail end survivors. Ana-Lucia....Libby...and Mr. Eko, a big black dude who beats the crap out of Sawyer, Michael, and Jin before dragging them off to his camp. Now...I don't know if they gave Rose's last name or not...but could Mr. Eko's first name possibly be....Bernard?
