How the characters on the TV show LOST crossed paths before the island
Chart lists which characters managed to cross paths before they were on the island. Weak lines represent weak links. For example Kate and Locke heard of Charlie's band (as no doubt thousands of others did), Jin saw Hurley on TV briefly (as did thousands of others).
A few obscure links that I picked up from various forums like TelevisionWithoutPity.com:
Hurley was on the TV when Jin paid his visit to the Korean minister's home
Hurley owns Locke's box company
The Lotto Number Calling Girl was Sawyer's one night stand (and the actor who plays Michael's real-life wife)
The Driveshaft song was played on an episode of Alias, which is produced by LOST's creator as well
If anyone has other links or see errors, feel free to post in the comments.
I ignored a few obvious ones like Jin standing behind Jack while he was trying to get his father's coffin on the plane.
