According to a casting call that Ausiello has seen, it looks like we're going to learn more about Sayid's past around the ten episode of season five. The casting call has gone out for a father, a 12 year old, and an 8 year old that all speak fluent Arabic.
It sounds a lot like the older boy, who's described as a sensitive type who's award that he lets down his father, could be everyone's favorite assassin, Sayid. What do you guys think? Will we be learning more from Sayid's past?
