Sayid had a fling with Shannon. He spent his life pining after Nadia. The writers told us over and over she was his true love. Then, in the final season, we're led to be believe it was really Shannon all along?
everyone's purgatory moment related to their island life.
Not Desmond's. Penny was never on the island. Yet Penny was his constant in both worlds.
And don't give me "but he was pining for Penny while on the island" because if that's the case then we're back to the Sayid/Nadia problem.
