The war will soon be over but a newly-returned Isobel still wants to use Downton as some type of convalescent home, an idea cleverly stalled by the clever Violet and Cora who want the house back the way it was.
Matthew is now in a wheelchair and spending a lot of time talking to Mary but the biggest shock for everyone is the arrival of a badly burned Canadian officer who tells the family that he survived the sinking of the Titanic and is, in fact, Patrick Crawley, heir to the Earl of Grantham. Having been desperately in love with Patrick, Edith wants with all her heart to believe him but it seems that she is the only one and he soon departs.
Bates is having yet more trouble with Vera and must make a trip to London to try and deal with her once again. Everyone is glad when the Armistice is declared but there are still many adjustments to make for every member of the Crawley family and quite a few for the staff as well.
A superb episode and one not to be missed. Amazing acting by all and a fantastic script.
