What area are you in? The dates listed are the UK dates, but it premieres in the U.S. on Starz first. So "End of the Road," aired last Friday on Starz in the U.S. (on 8/26), and presumably aired last night in the UK on 9/1.
Tonight, The Gathering will air in the U.S., and next Thursday in the BBC on 9/8/11.
