Like the middle section survivor background cast, those that comprise the background Others also have recurring roles. Two of the Others background was formerly background from the tail section survivors (in addition to the named "Tailie" roles of Emma, Zach, and the guest character Cindy, who also joined the Others); see #8 and #9 below. This list is for background actors only, and does not include guest actors recruited and cast for specific roles, who are always credited for their appearances such as Mikhail, Bea Klugh, Karl, Isabel, Ryan Pryce, Amelia, Adam, etc. Also, the named Others characters of Ivan, Jason, Matthew, and Luke also appear as recurring background cast in episodes where they are not credited; these characters are listed in the next table.
