Lawyer Coming to LOST - Spoilerish

Source: Casting Scoops: 'Lost' Finds New Villain Ausiello Files EW.com

Lost is on the prowl for an actor to play Dan, a high-priced attorney who
can be friendly, but has a "real menace lurking below the surface." Paging Doc
Jensen.... "Of course, Dan is yet another Biblical name -- Dan being another one
of Jacob's sons. (Also see: Benjamin.) According to Wikipedia, he was the one
who hated Joseph so much he conspired to have him thrown into a pit, then
smeared blood on Joseph's robes to convince Father Jacob that wild animals
killed him. My hunch is that Dan is a minion in the employ of Charles Widmore,
someone who executes a lot of his dirty work -- like, say, working with Libby to
further manipulate Desmond into that yacht race. Remember when Sun and Widmore
seemed to strike some kind of ominous alliance in the season finale? "Dan" will
serve as Widmore's liaison with Sun." Thanks, Doc! You took the words right out
of my mouth! (Additional reporting by Lynette Rice)
