I don't think the island brought them together. Believe it or not it’s the simple concept of “6 degrees of separation”. Just coincidence, I don't think it has anything to do with the island or their being something to it. That’s why the producers have been astonished at all the weird theories fans have came up with. I don't think they ever intended it for it to mean anything. But because they listen to what fans have to say I bet they will try to add it in to the script some how but I don't believe this was their initial intentions.
