There's little reason to believe every single Dharma person was on the island when Ben killed them, and you'd think the company's off-island employees would have been trying to find out what happened to the facility. Plus we still don't know the origin of the "indigenous" Others like Richard.Regarding Dharma. One thing that has bugged me is if Ben killed off the on-island Dharmas during the purge, and if he did take over the communications, why are the Dharma food deliveries still coming? Maybe the off-island Dharmas are not sure what really happened, therefore are still delivering the food in the hopes someone is still alive?
And Kelvin was a Dharma employee in the Swan station (I guess "employee" is the right term) up until 9/22/04 when Desmond killed Kelvin and the plane crashed. Desmond was under the impression the Others were evil. Can we assume Kelvin was really an Other and not Dharma, or did he survive the purge and not know what was going on? We know they (the Others) could see into the Swan station, therefore they were aware of who was there.
Ooooo! Another question. Kelvin told Desmond it was dangerous to go outside the hatch. Could this be a result of the poison gas from the purge? Could Kelvin have been trapped there since the purge? We do know that Kelvin did go outside without proper protection because that is how Desmond figured out the ruse and followed him outside, leading to Kelvin's death and the plane crash.
Kelvin--Dharma or Other?
How long ago was the purge?
How soon will my head explode from all the unanswered questions?
