Fringe: Meet Henry Ian Cusick's Secret Agent Partner

Fringe has cast Australian actress Georgina Haig to play the partner of Lost alum Henry Ian Cusick's character, a show rep confirms.

As first reported by TVLine, Haig could potentially recur as Etta, a new Fringe agent who debuts in Episode 19. Although original breakdowns described the agents roles as "Alternative Universe Agents," Cusick's G-man is said to work for the FBI.
