Lost alum Henry Ian Cusick is heading back to Hawaii, with a plum role on Hawaii Five-0.

The dashing Scotsman will guest-star in the Season 4 premiere as Ernesto, a tough, fearless and ruthless member of a terrorist group called the National Liberation Movement. Provided he makes it out of the mayhem he makes alive, he possibly could reappear like a bad penny.

Asked to comment on Cusick’s character, show boss Peter Lenkov — who teased the Lost alum’s arrival with the photo below — said, “Well, he’s got the balls to take over the palace, Five-0’s HQ — so what more is there to say?”

Hawaii Five-0 opens its new season on Sept. 27, now airing Fridays at 9/8c.

Cusick’s previous TV credits also include arcs on The Mentalist and Body of Proof, and Season 1 of Scandal. He next costars on The CW’s The 100, premiering at midseason.
