 The scene in which Desmond goes nude swimming was not included in the same form in Etheridge 's version of the episode ; however , Thomas enjoyed the take that was eventually used more , so he put it in the final cut . Because the show could not show full nudity , they gave the stunt performer who was filling in for Rudd flesh @-@ colored swim briefs and put him out of focus so they could notify the network that the man out of focus was indeed clothed . The lights that can be seen in the distant background of the scene illuminating the bay were placed nearly ten miles away by grips .
