‘Downton Abbey’ Season 6 Spoilers: First Promo Teases Emotional Final Season; Is Someone Leaving? [VIDEO]

The final season of “Downton Abbey” is almost here. While Americans have to wait until January, British viewers only have a month left before Season 6 premieres. ITV has released the first trailer for the finale, and it looks like an emotional last season.

In the promo video, most of the characters look very sad. It isn’t clear why, but Lauren Aquilina’s cover of “Time to Say Goodbye” only makes it feel more depressing.

Mr. Carson (Jim Carter) packs up a suitcase and removes his nameplate, but is he really leaving Downton? Perhaps he and Mrs. Hughes (Phyllis Logan) are just moving into a new house after their wedding. Still, he seems a bit too sad as he sits on a bed alone.

Other characters also look distraught throughout the promo. Though Mary (Michelle Dockery) and Violet (Maggie Smith) never really look too happy, even gentler characters like Anna (Joanne Froggatt) are seen in tears. Mary also appears dressed for a funeral in one scene.

The “Downton Abbey” Season 6 trailer gives a couple quick glances at happier times as well. Edith (Laura Carmichael) seems very happy while talking to an unidentified man. Could she finally find love after Michael Gregson’s (Charles Edwards) death?

Elsewhere, the downstairs staff seems to be in a church. Since they aren’t shown at regular services too often and they’re smiling, it’s probably a celebration like a wedding. Could it be Mr. Carson and Mrs. Hughes' nuptials?

The gloomy promo doesn’t indicate that everyone will have a sad ending. Executive producer Gareth Neame promised that some characters would live happily ever after, but he hinted that a few might end in tragedy as well.

“We've got 20 or so main characters. There's a lot to get done in these final nine episodes,” Neame told TV Guide. “This is ultimately a happy show that people love, so I don't think we're going to end with lightning striking the house and the house is exploded or something. But not everyone will have a happy ending.”

Rob James-Collier, who plays Barrow, echoed that sentiment when he teased Season 6 plotlines to Red Carpet News. “I can guarantee a wedding and the odd funeral or two…or nine,” he teased in June. Fans will have to hope their favorite characters survive.

“Downton Abbey” Season 6, the final season, premieres Sunday, Jan. 3, 2016 on PBS.
