This entry is not included in The LOST Encyclopedia since the Season 6 "Sideways" reality was only covered in a few main character pages at the back of the book. But this is my blog, so I'm including David Shephard!
David Shephard, son of Jack Shephard and Juliet Carlson,
was portrayed by Dylan Minnette. He appeared in the Season 6
episodes "Lighthouse", "The Last Recruit", "What They Died For"
and "The End."
The above autographed photo is a screen capture taken from
the Daniel Faraday/Drive Shaft concert in the LOST finale, "The End".
