I posted the quote here maybe a month ago. It went something like "there are no spaceships, there is no time travel". They were reassuring people that everything on the island is normal and "based on science" (another quote that does exist).
wasn't the quote referring to nothing supernatural being revealed
yet? as in, season one, when the quote was made?
even then, with smoke monster appearances and sound effects and all through out the first season, as well as a number of prophetic moments, walt's "powers", and other such happenstance, i think it was established very early on the show was going to have sci-fi moments.
they did say stuff like "no one comes back from the dead" or "no time travel" which they ended up contradicting.
i dont know if they ever said either. if they did, i don't recall seeing it. i
do remember producers saying that the tv show wasn't a dream and that the characters were not dead (at least, seasons one through five and half of six)
