Question: What effect, if any, will the Lost arrests have on Michelle Rodriguez's and Cynthia Watros' roles or futures on the show?

Answer: Little if any, I'm told. Apparently, if they get their driving privileges revoked, there's some kind of law that allows convicted DUIers to drive to and from work. So, if you happen to be in Hawaii and see someone who looks like Ana Lucia behind the wheel, pull the frak over and pray for your life.
