The story of Marc Silverman
Description
Marc Silverman was Jack's best friend since childhood. On one occasion, Jack unsuccessfully attempted to defend him against schoolyard bullies and was also beaten.
Later in life, Jack talks to Marc about how he can still back out of the speech at his wedding to Sarah. Marc was annoyed at the fact he has to wear a real tie instead of a clip-on tie.
Marc with Jack asks Marc if he feels alright about being his best man, as Jack knows he doesn't like talking in front of crowds. Marc says he will be fine after 8 beers. Jack warns him to clean his teeth otherwise Sarah will know that he was drinking. Marc promises that he will brush his teeth, and tells Jack that he can still back out, if he wants to.
Marc was later best man at Jack's wedding to Sarah, and then introduces Sarah as "the future Mrs. Jack Shephard". She then tells the rehearsal party the story of how she met Jack; the car accident, her broken back, Jack's promise to fix her, and his miraculous success. Because of all this, she will dance at her wedding. She finishes her speech, by toasting Jack as a hero.
