after the events of the film, Jack and Anne are on a boat with Houston Brooks as Jack questions what reason on why are they on this boat into the Arctic Ocean as well what are they waiting for as Houston responds by saying "hold on..... hold on" as it pans from afar the now broken iceberg what once contained something inside now is open as as the all too familiar dorsal plates are showing surfacing and breaching the waves like a shark in the ocean.
