I have heard about this "clue" in the pilot episode for some time now. I have rewatched episode 1 again and again and I think I finally picked up on something, but Im not sure what to make of it.
When the monster shows up the second time, you can just barely make out this conversation off camera.
ROSE: "Something about that sound is VERY familiar."
SOMEONE?: "Where are you from?"
ROSE: "The Bronx."
Nothing else in that episode feels like it would be a clue. Anyone from the bronx ever seen smokey around the neighborhood? Can anyone shed some light on this?
