Jackson: We've gotten closer and closer to finding the location of the Lost City but it turns out we've been looking in the wrong place all along. Now, we thought we had a Stargate address -- six symbols representing coordinates in space that determine the location of the planet the Ancients went to after they left Antarctica. Now, recently we determined a seventh symbol. (adds symbol to board)
Weir: The point of origin, Earth.
Jackson: That's not it.
McKay: Then your address must be incorrect.
Jackson: Not incorrect… incomplete.
Weir: What are you saying, Doctor Jackson?
Jackson: It's an eight symbol address. What we're looking for may be further away than we ever imagined, but it's not out of reach.
Jackson: Atlantis. I think we can go there.
