It began with a prop. A poster behind Sarah as she visits Jack in the hospital reads
"Ácido Fólico", or Folic Acid in Spanish. We knew this was probably not from the props department of Lost, because small hospital details like in previous episodes have been from the real life location itself, whether it be
St. Francis Hospital,
Kahuku Hospital, or the new University of Hawaii
Medical School. This poster was a calling card that this scene was not filmed in Hawaii, although other hospital scenes from this episode indeed were. Confirming this hunch this week was
DocArzt of Thetailsection.com, who discovered from
Kristin of E! Online that this was none other than the set of Grey's Anatomy.


The styles of the rooms in Sarah's scene from Lost match with Grey's Anatomy, and the horizontal blinds on the windows and doors are the first giveaway. Looking more closely, the door handle, light switches, and wall trim match, as do other details in other screencaps: medical cabinets, supply racks, and examination lamps. Read more at our
Grey's Anatomy Set page.
However, the other hospital scenes, such as those with Dr. Hamill, were filmed in Hawaii, almost certainly at
St. Francis Hospital Liliha.
