I cried buckets - so did daughter and hubby! It was a wonderful, touching episode. We have loved the whole thing, since the first episode.
I don't think there'll be another - the last couple of series have been extensions (stories made up by the writers rather than taken from the books), and I don't see how they could do more after last night's - it had the 'feel' of a 'last ever', especially with the tone of the final voice-over.
