There's no on-screen episode titles. BBC uses generic Episode 1, 2... However, the series 4 was done in co-production with US Starz network. And Starz have a meaningful title for each episode. So, the question is – since we use BBC One as primary network, should the episode names be replaced with generic ones, or left the Starz' names, since they're also official?
Also, I've noticed that we have Starz' airdates for series 4 (whose are 6 days earlier than BBC's). I will change them to BBC dates, but IMO editor's wiki should be created, covering the dates and names issues.
