The sixth and final season of LOST began airing on February 2, 2010. The primary story line continues after the detonation of the hydrogen bomb with all the main characters returned to 2007 unharmed, but still on the Island. Locke, now revealed to be The Man in Black continues trying to gather all the remaining survivors - mostly drawn to the Island by Jacob for the purpose of selecting one of them to replace him as the protector of the Island.

This season introduces the concept of the "flash-sideways" which is later revealed to be an afterlife dream-state. It is a dreaming state which the castaways have created for themselves before "moving on" to a more permanent afterlife setting. The "flash-sideways" presents events as they would have happened if there were no crash and major events in their lives had happened differently. This "flash-sideways" timeline cannot be truly said to be a flash-sideways, a flashback or a flash-forward. It exists outside of time as we know it and serves as a limbo or temporal afterlife until the characters are ready to continue their journey together.
