The “research laboratory” where Desmond met his friend Donovan (“Flashes Before Your Eyes,” Ep. 3×08) was inside historic Ali’olani Hale, home of the Hawaii State Supreme Court (417 S. King St.). The office where both Claire met would-be adoptive parents (”Raised By Another,” 1×10) and where Micheal faced his ex (”Adrift,” Ep. 2×02) was a conference room in the same building.
