Sorry about that Q.  It suddenly occurred to me as I was watching it that you might do a synopsis, so I paused the playback and posted that last post.  
Thank you for taking the time and trouble for the synopsis though.  My memory these days is appalling and I really needed to catch up on what was going on.  I'd forgotten (for example) what had happened to Amy and Rory.  Because of that I didn't understand why the Doctor was shutting himself off.
Your synopsis is very useful to me.  
 
By the way - is that Patrick Stewart doing the voice of the snow?  
 
 
And I finally got to see the bits in the cemetery that were filmed across the road from me.
