I thought I would repost two fics I wrote last summer for the luau. They revolve around the idea of the castaways deciding whether or not to go back in time and stop the crash, and what would be the consequences of that choice if they did. The O6 stuff is dated but I thought the concept was topical.
Something From Somewhere, Sometime (Charlie/Claire, ensemble) - PG 13 - Charlie's wish for the Oceanic 6's return comes to fruition and hard choices are made for the future and the past. Would you stop the plane crash if you could?
Collison (Ensemble) - PG 13 - A sequel to Something from Somewhere, Sometime. This looks at what would have happened if Flight 815 hadn't crashed. Some things are just meant to be.
