Well, it looks like the world is a very small place. This season, Hawaii Five-0 will get its ninth Lost alum guest starring in the CBS procedural. This time, it will be William Mapother, who played Ethan Rom on ABC’s Lost. Other former Lost actors that have appeared on Five-0 include series stars Daniel Dae Kim and Jorge Garcia, Terry O’Quinn, Henry Ian Cusick, Sam Anderson, Tania Raymonde and François Chau.

Hawaii Five-0 has never shied away from using former Lost members in the past as O’Quinn has become a recurring cast member throughout the first few seasons and fan favorite Garcia getting promoted to a full-time cast member this season.
