Yeah, cool episode. First thing I thought when I saw that box was Hellraiser, heh. Nope, Marshall didn't pick up the voice. As for Jack's look, it was in response to Lauren ending her sentence to Vaughn by calling him "love." That was exactly how Sark was talking and so I think Jack has begun putting two and two together. I got it TiVo'd so I'll probably check it out a couple more times.
