Lady Mary and her frightfully common suitor are now engaged. Muddying these clear, business-like waters however is Lady Mary's longing for Downton Abbey's heir, Matthew Crawley. Which raises the question - what happened back then when one party wanted to break off an engagement?
The issue of whether girls are entitled to inherit - be it the throne, a title, or a whacking great pile somewhere in the heart of Berkshire floggable to passing film crews - isn't one that'll affect most of us on a personal level. And yet I still find it shocking that it's taken until 2011 for it to come up as a parliamentary issue.
For many of us - especially perhaps Liam Fox this week - escapism is everything. From boredom. From endless Loose Women. From feelings of being as vastly unfulfilled as a Little Chef chef. Downton Abbey is one such retreat. It looks nice, it sounds nice and I bet it would smell nice too.
While Downton Abbey begins to flex its narrative muscles, Spooks, in its final season, has the far harder task of going out with a bang, not a whimper, while somehow satisfactorily tying up all the loose ends - by which, obviously, I mean section chief Harry Pearce and trusty sidekick Ruth Evershed finally eschewing love for country in favour of something a little less abstract.
