LOST: Epilogue

"Well, this is a place that you... that you all made together so that you could find one another. The most important part of your life was the time that you spent with these people. That's why all of you are here. Nobody does it alone Jack. You needed all of them, and they needed you."

The 'Flash-sideways' Universe was revealed to be a purgatory-type place where all the survivors would meet after they died. Throughout these unique flashes, they were living their lives without their past flaws and eventually they all experienced a type of awakening where they would remember when they were alive. At this crucial point, they all met in Eloise's church to move on to the next life.
