When Eko asks Yemi in his dream for forgiveness he replies: “Your work being done in this place is important Eko, it is more important than anything!” and “what’s done is done.” This supports the purgatory theory: Eko carries some heavy sins, and when asking his brother who is a priest for forgiveness he says “what’s done is done”. This fatalistic response could mean his life is behind him (Eko and all the ‘survivors’ died). In this context “Your work in this place is more important than anything” could mean that what he does on the Island could still give him access to heaven.
