Thanks to Miss Ford from FBL for the translation of a portoguese set report.
I went back where the staff had gathered. Sawyer had arrived on the island. Kate too, and both were in the boat. The production staff tried to keep away people who were snooping around, so it was difficult to see the rest of the filming.
By late afternoon, when I was leaving, the boats began to bring the actors back to "the continent" - which is just a matter of perspective, as the mainland is the island of Oahu. A friend of mine took picture, on the boat, of Sawyer and Kate, who look like they were tired, after another exhaustive day of filming.
