Fail Safe Key
Ok guys even for me, this one is a stretch but when I came up with the idea I wasn’t exactly sober.
In the first episode of season5 Daniel says “you can’t change the past, no matter what you do, it will find a way to fix itself, can’t change the past”
Daniel tells Sawyer it is pointless to knock on the hatch back door “it didn’t happen, so it can’t happen”
But then he has this idea, flips through his little book full of science stuff and DI information (he obviously studied the DI before he came to the island, he even says so) and decides to knock on the door himself because he knows Desmond, and apparently knows that Desmond is special!
Daniel is our resident lostie physicist so we pretty much have to take him at his word. He knew what time to meet Chang, what day to arrive on the island etc… HE KNEW WHEN THE INCIDENT WAS GOING TO HAPPEN!
This is why he came back, he said that THE HYDROGEN BOMB COULD NEGATE THE ENERGY and therefore the button never made/needed and the plane wouldn’t crash.
A lot of people on this site have stated that they think Juliet was the major variable, that she changed her mind to help Jack, ended up at the bottom of the hole and started hitting the bomb with a rock.
My theory as follows –
In another timeline Juliet did not help Jack (keep in mind we have yet to see how they get out of ’77) but however the events play out, the bomb still sits at the bottom of the hole and the DI digging causes the incident.
What if that bomb becomes the fail safe? I mean why else does the hatch have blast doors? They sealed off the entire swan site with cement and left a spot with a key that can NEGATE ALL OF THE ENERGY AS A LAST RESORT.
The key could be the detonator. When Desmond turned the key, the sky turned purple, everyone heard a loud noise and Desmond went somewhere.
What if he went to alternate reality/timeline. The Eloise he meets, the man with the red sneakers, all kind of a down the rabbit hole/wizard of oz type of thing. He has a chance to marry Penny and be happy but he doesnt take it, he throws the ring away which causes the timelines to merge and he is back on the island in 2004. Anyone ever notice that it seems like their are different versions of the Penny & Desmond marina pic?
Maybe when Desmond turned the key, the energy was not as exposed as when Juliet smacks the bomb. What if the same way the fail safe sent Desmond somewhere will send our losties somewhere as well – To an ALTERNATE TIMELINE/REALITY where they have some memories of the island but are not sure if its real. They will run into eachother and eventually figure out that they belong somewhere else, at this point the timelines/realities will merge and we will be back in action!
*I know Desmond’s flash was purple and the second time it was white – sorry!
*I know Locke was in the hatch when Desmond turned the key – All of the DI was around when the bomb went off and Radzinsky still builds the swan, paints the blast door map. Chang still makes the swan orientation film that Radzinsky edits. They obviously don’t flash. Only the important people do!!!!
Rip it apart!
