The final season of "Downton Abbey" is about to premiere in the U.K. next week, and Jim Carter, who plays the no-nonsense butler Carson in the show, has given away some major spoilers for the drama's finale. 

"We don't finish on a climactic note," said the 67-year-old actor during a recent interview with Event magazine. 

Far from the show's 2012 finale which saw the death of Matthew Crawley, Carter said that the series' end will be low key, which will nonetheless be an appropriate end to the much loved show.

According to Carter, the very last scene is set on New Year's Eve in 1925, and will see the servants gathered in the castle's great hall for a party. The scene that the actor described could be the staff's last night at the castle together, as it was previously reported that in season 6, the Crawleys will be reducing the staff and closing up the castle due to the economic crisis.

"All the servants are gathered together in the hall. It is New Year's Eve, it's candlelit and there are Christmas decorations left over. It is dark and we are quietly sing Auld Lang Syne," said Carter. 

The actor also hinted that the finale will see Carson tying the knot with Mrs. Hughes (Phyllis Logan), as he revealed one of the last things he says on the series. 

"One of the last lines is when I say, 'It's going to be a different life.' Mrs. Hughes says, 'Yes, but together we'll manage," Carter said. 

One thing that the actor can be sure of is that everybody will be in tears after watching the season 6 finale, and he admitted that while he was filming the final scene, he surprised himself by bursting into tears. He also said that after they wrapped up the scene, he addressed the crew and he "completely choked up." 

"I think people will be very pleased," Carter said of the finale. "They'll need two hankies."

The sixth and final season of "Downton Abbey" airs on Sunday, Sept. 20, at 9 p.m. on the UK's ITV1 and will premiere in the U.S. on Jan. 3, 2016 on PBS.
