A continuous shot shows Hideko and Sook-he as they pass through a gate, Hideko first, then Sook-he carrying her luggage. The camera pans over the gate and shows the two of them from behind, now crossing a field. Almost identical to the famous shot, when Jill McBain along with the baggage porter crosses the station building and walks over to Sweetwater.
The octopus in the background of the basement is a reference to the scene in Oldboy where a live octopus is eaten, another film by the same director
