"King of the Castle"
Lost: Missing Pieces, Episode 3
Where it fits:
Sometime after "Stranger in a Strange Land" (3.09) and before "The Man from Tallahassee" (3.13)--presumably this is what Jack is doing while Kate, Sayid, and Locke are trying to find him at the Barracks. Maybe Locke is playing chess with the computer at the same time...
Since this review is my first for Missing Pieces, I feel like I should say a little about these webisodes (or perhaps mobisodes depending on how you first watched them). I didn't really know what to expect out of these brief films--Would they just be deleted scenes? Would they be important for the overall plot? Would they give clues to the upcoming season (#4)? After watching them, I realized that like Lost itself, these missing pieces don't fit easily into any categories!
