There were snarky lines that acknowledged the show's bombastic tendencies-- Kate asks, "Christian Shephard? Really?" There were throwbacks to old episode titles-- "What happened happened," Jack promises, while Sawyer comments on Jacob's "long con." And there were even camera shots that deliberately echoed the iconic images of the past, like Jack and Locke staring down the hatch/the well, or Locke wiggling his toe. Lost has always rewarded its diehard fans with constant Easter Eggs, and bless them for doing it in double time for the finale.
