Damon Lindelof: I think that Ben quite clearly says, "let me put this into terms that *you* can understand, John," which in, in, in knowing that they have some sort of file on Locke, and they, they refer to having kn- kn- knowledge of the fact that he worked in a box company. Then maybe this is just, some sort of, uh, metpahor that Ben is using to explain, uh, whatever this box construct is on the island. Because I think it would be sort of silly to walk to the middle of the island and there was like, kind of a big large refrigerator box sitting there, and Kate's horse comes tromping out, and Sayid's little cat, and Jack's Dad, and you know, I don't know, that would kind of be the worst idea in the history of ideas.
Carlton Cuse: Yeah, besides, the best box idea was done in that show Prophet, where there was the naked guy sleeping in the box.
