Ok ik heb de goede verklaring:
No...first of all it wasn't an alternative time line at all
the island wasn't purgatory, the island was real. everything in the OT actually happened. We left all of the characters (dead or alive) at the point when Jack died. Whenever they all died, they arrived in this alternate timeline (purgatory) together, before they were ready to move onto the afterlife proper
It was a meeting place for them all so that when each of them died they would be with the people who changed their life - regardless of WHEN they died. And Desmond's purpose was to get them all together so they could move on together.
If anything it was their own personal purgatory.
Think about it. Ben, the most sinful good guy, wants to go in the church, but says he "still has things to work through." Locke after wakes up, he tells Jack that Jack had no son. End scene with a guy named Christian Shepherd.
Ik krijg nog geld van je.
