Several weeks ago, Entertainment Weekly published an article in which they referred to Sayid using his first and last name, "Jarrah." I asked their staff where they got this information since we have never heard or seen Sayid's last name on the show. Their response was "The publicist got it from the show's writers."

I'm wondering what other information we, the viewers, are supposed to "know" from trolling the Internet instead of simply watching the show.

As far as I'm concerned, it's not his last name until it happens on the show. What say you?
