Since the premiere of season 6, fans of "Downton Abbey" have been hoping that Lady Edith's (Laura Carmichael) fortunes will change. So far, the middle child of the Crawley daughters has had the worst luck. If she's not entangled in a spat with Lady Edith, then her love life is messy. Show creator Julian Fellows hinted at a future that's happy for Lady Edith but crushed all our hopes once again.

In the Christmas Special episode, the last of the series, we hope that all the Crawleys are comfortable and settled in their present circumstance.

The synopsis for season 6 Christmas Special hints at a possible reconciliation between Lady Mary and her younger sister, Lady Edith. We know that Bertie Pelham's mother will appear in the series finale, but it remains to be seen if she will embrace her son's love interest, faults and all.

Furthermore, the Christmas Special episode will focus on Lady Mary and Henry Talbot's marriage at Downton. The car racer, who isn't used to a sedentary life in the country, will struggle to accept his new life and the responsibilities that come with being a husband, no less to Lady Mary.

The end of the British period drama also depicts the end of one character's journey. The character in question is Thomas Barrow (Rob James Collier). In the promo for the Christmas Special episode, he says, "I came as a boy, I leave as a man."

No doubt Master George will miss him immensely, and so will the fans of the show.

"Downton Abbey" season 6 Christmas Special's synopsis reads:

"Mary endeavours to build bridges with her sister while Edith's secret continues to pose a threat, despite having nothing left to lose. As Henry settles into the role of husband and stepfather, finding his place at Downton proves more difficult. Below stairs, Carson faces some personal challenges, which prove that even he is not invulnerable to change."

The last ever episode offers all the love and loss, happiness and heartbreak of Downton Abbey, and as the family and servants prepare to welcome 1926, they celebrate an unforgettable New Year's Eve together at the great house.

Spoiler TV reported, "Joining the cast as a guest is Patricia Hodge (Miranda) who plays Bertie Pelham's mother. Also returning are Lily James (Cinderella) and Matt Barber (Being Human) as Lady Rose and Atticus Aldridge, alongside Lady Rose's father, Shrimpie played by Peter Egan (Unforgotten)."

"Downton Abbey" season 6 Christmas Special airs on Friday, 25 December at 8.45pm on ITV. You can live stream the episode via ITV Player.
