It's been a long haul for faithful "Lost" viewers, but the end has come.
For six years, we've cheered on a complicated batch of plane crash survivors as they battled polar bears, ageless island inhabitants, time travel, the smoke monster and one another.
We've watched Sawyer morph from a sarcastic egomaniac to a sarcastic unlikely hero with a hardened heart of gold. We've cheered on Hurley as he found his confidence. We cried when Jin and Sun were finally reunited only to drown in a crippled submarine.
And we've been endlessly teased with a twisting labyrinth of questions as the show wound itself around in circles of mythology, faith and science fiction.
To be fair, viewers have been given the healthiest dose of answers since the show began -- the origins of the Adam and Eve skeletons found in season one, the birth of the smoke monster and how Richard Alpert has remained so gorgeously ageless for centuries.
But there are still a smorgasbord of mysteries left. Will the "Lost" series finale (Sunday, May 23 at 9pm ET on ABC) be able to answer them all?
It's become common theory in the blogosphere that the meaning of the series of numbers, central to so many of the island's events, may never be revealed.
The numbers -- used by Hurley to win the lottery and Desmond to keep the hatch from exploding -- have popped up dozens, perhaps hundreds, of times over the course of the show.
