Warning: Spoilers ahead! Read on if you want to learn more.

As is evident from the trailer released for “Downton Abbey’s” last episode by the network, it seems that there will be lots of emotions involved, People reports. Television’s favourite aristocrats and their servants will bid adieu to their viewers who were with them for over five years. Michelle Dockery, who plays Lady Mary Crawley said that she “felt sick” shooting the finale episode, Telegraph UK reports.

The episode opens with “Auld Lang Syne,” playing in the background. The family celebrates Christmas with the huge hall decorated by the Crawleys with lots of fanfare, Vanity Fair reports. The family partake in the festive merriment by having champagne.

But, amid all the celebrations, the mood is also contemplative as they discus that the times are changing and also the Yorkshire country house, Entertainment Weekly reports. “We never know what’s coming of course. Who does?” Robert (Hugh Bonneville) asks in the clip. He adds that they have a good chance.

Meanwhile, Henry Talbot (Matthew Goode) looks in deep thought as he strives to adjust to married life. Thomas Barrow (Rob James-Collier) departs from Downton after his suicide attempt in the last series. “I arrived as a boy, I will leave as a man,” his last line is moving, but he smiles.

Lady Edith (Laura Carmichael) unfortunately may not have a happy ending. She bumps into her former beau Bertie Pelham, but in the trailer there is no mention about their relationship. Also, Lady Rose (Lily James) will also return to the house, but she is not seen in the trailer. She is reportedly expecting a baby with Atticus Aldridge (Matt Barber).

Meanwhile, "Downton Abbey" show creator, Julian Fellowes has teased that a Downton movie could be a possibility, Vulture reported in November. Also, executive producer Gareth Neame told that they have been talking for a Downton film, TV Insider reports.
