P.S. Regarding last week's episode: people reported hearing "We are the survivors of Flight 815," while closed captioning (and I saw the pictures someone took of the screen to prove it) read, "There were no survivors of Flight 815." Over at Snarkfest, someone pointed out that, while they can't find the actual post, supposedly the writers confirmed over at The Fuselage (a board where the cast and crew are known to join in) that the voice on the other end was supposed to say "We are the survivors of Flight 815." So apparently closed captioning really did say "There were no," but closed captioning (as it sometimes is) was wrong.
I will leave it to y'all to discuss whose voice it actually was, although I have heard some interesting theories.
