It's going to be an emotional final episode of Downton Abbey as something important might get revealed.
On Monday, a promo for the last episode of the series was released that shows how everyone will come together for their final moments together. Mrs. Patmore points out that they've been in each other's lives for a long time as Lady Mary contemplates if this could really be the end for everyone.
There will be scenes dealing with drama as characters wonder what sacrifices should be made for love. There will also be smiles as more opportunities come aboard.
The last part of the promo has some suspicion though as Mary talks about her sister Edith saying "sisters have secrets."
See the promo below.
There was also a podcast with some of the stars from the British drama who mentioned why they're keeping important details about the finale to themselves. Jim Carter, who plays Carson, explained that it's best to wait it out so everyone can feel completely satisfied.
"The way television works is people watch and they get excited about the story, but if you have told them, some idiot from Yorkshire's told them the story beforehand it ruins their pleasure. And then they come looking for that idiot and persecute him," Carter joked. "So I don't want to be in that position."
The Downton Abbey finale airs on Sunday, March 6 at 9 p.m. ET on PBS.
