Synopsis by Rovi
The title of this episode translates as "Blank Slate," which is as good a way as any to describe what the 48 survivors of a mid-air plane crash truly know and understand about one another as they acclimate themselves to their new Pacific-island surroundings. Almost as mysterious as the strange topography and stranger wildlife of the island is the clouded past of Kate (Evangeline Lilly), who, it is revealed through flashback, was a recently a fugitive on the run. Only one passenger, who may be dying, knows her secret...until he passes it on to two other survivors. Meanwhile, the mysterious Locke (Terry O'Quinn) forms a bond with young Walt (Malcolm David Kelley), much to the dismay of Walt's father, Michael (Harold Perrineau).
