Jeff Fahey, His Role?

First and foremost, thanks to DarkUFO for informing us about Jeff being casted to the on LOST.
The role of Mr.Fahey has yet to be spoken of by the Producers. According to many different sources, Jeff maybe playing an older, beaten up Gerald Degroot. At this point it seems very unlikely. The most likely role Jeff will be playing is that of the freighter captain and a very clever one. Only time will tell.
