Oh, The Numbers. The six numbers that haunted LOST fans for Six Years. Those pesky numbers kept on showing up on props, signals, odometers, cave walls, lighthouse dials, lottery tickets, flight numbers, the hatch door, computer screens, computer read-outs, and numerous theories.
The Numbers. 4, 8, 15, 16, 23, 42
Was there any final conclusion to what the Numbers represented?
I guess it depends if you think the Numbers were important.
Hurley thought the Numbers were important: as bad luck, a curse or a bad omen, every time he encountered them. Danielle must have thought the same thing, as the signal repeating the numbers led to her coming to the Island.
Many fans speculated that the Numbers had to deal with Dharma or some unknown group trying to change the values of the Valenzetti Equation. That theorem is a 1970s equation that attempts to determine the end of humanity. Dharma was conducting various experiments to either create, change or modify life in an attempt to change the coefficients of the equation to save the world. But that does not explain why the numbers were broadcast as an island location beacon; why they were on the hatch serial number; or why those numbers had to be put into the Swan computer in order to avoid a release of electromagnetic energy.
The fans really, really, really wanted an answer to the Numbers. They wanted the Numbers to be foundational to the whole story line. They have to be disappointed.
We found in the lighthouse and in MIB's cave, the Numbers allegedly represented potential Candidates.T he Numbers represented the last six candidates to succeed Jacob as island protector:
4 was John Locke, who was killed off the island, and his body taken by MIB to create Flocke.
8 was Hugo Reyes, who feared the Numbers the most, and wound up the guardian after Jack.
15 was James Ford, Sawyer, who never wanted to take responsibility for anything until he time traveled with Juliet.
16 was Sayid Jarrah, who was taken over by "The Darkness" and MIB.
23 was Jack Shepard, who defeated MIB and became the island protector for just a few short hours, until Flight 316, piloted by Frank, allowed Sawyer, Kate, Miles, Claire and Richard to leave the island.
42 was for Jin Kwon, who never left the island, who killed himself to stay with Sun in the sinking submarine.
Were the Numbers critical to the final explanation of the show? Or were the Numbers merely a clever plot device, a red herring, to keep fans watching intently and discussing the meaning of them from week to week? (I really liked by Periodic Chart of the Elements Theory). The conclusion, as written, the Numbers were basically used as immaterial bait to keep fans interested in the show. The function of the numbers being so coincidental throughout the seasons is an easter egg not found and left to rot in the yard. The idea that the Numbers were merely symbolic placeholders in Jacob's still convoluted plan to maintain the Island special powers seems disappointing, especially to die hard sci-fi fans looking for a deeper explanation. There is little elegance in the Numbers being merely a scorecard.
Considering the lighthouse contained hundreds of names and numbers crossed off during the centuries, the LOST numbers appear just to be random footnotes. And in the vetting of these final Candidates, there are very little cohesion or moral values between the actual characters. In fact, three had violent or criminal pasts (Ford, Kwon, Jarrah). Two were real life losers (Locke and Reyes, until he won the lottery then began to lose his mind). So by default, Jack winds up as the least flawed person on this list, if you exclude his personal life and drug addiction. In fact, none of the final Candidates had high moral standards to protect something so important as the Light and Island, the source of life, death and rebirth. I guess it is true, when your number is up, your number is really up.
