Simone Dusek is a Doctor with the CDC- (Centers for Disease Control and Prevention) who was seen briefing Hawaii Five-0 Task Force member, Officer Kono Kalakaua on the effects of weaponized smallpox during the Hawaii Five-0 Season 2/NCIS: Los Angeles Season 3 crossover episode, Pa Make Loa (episode).
She later contacted Kono to inform her that the vials that Kono's colleagues, Detective Danny Williams and Kono's cousin, Lieutenant Chin Ho Kelly as well as NCIS Special Agent G. Callen and Special Agent Sam Hanna had recovered from Dracul Comescu did not contain smallpox, forcing the team to head to Honolulu International Airport and then eventually Los Angeles, California after learning that a possible suspect had arrived in LA with the smallpox vials.
