Five years ago, Julian Fellowes presented us with a period drama that has explored a gamut of human experiences, ranging from marriage, motherhood, love, loss, death, sibling rivalry and more. It is satisfying to know that the last five seasons of "Downton Abbey" captured the socio-cultural movements of early 20th century Britain, and depicted it sans judgement.

As the series moves through a timeline when aristocracy declined in England, the cast of "Downton Abbey" has bid goodbye to the estate and to their loyal fans. The recently released season 6 trailer of "Downton Abbey" resonates with that gut wrenching feeling that accompanies a good bye.

The one-minute video clip shows glimpses of what is to happen in the series finale: Mr Carson (Jim Carter) and Mrs Hughes (Phyllis Logan) marry; Edith (Laura Carmichael) finds herself a suitor; Mary (Michelle Dockery) and Anna (Joanne Froggatt) say good bye; Daisy (Sophie McShera) joins the Mason farm and finally, the Crawleys assemble in front of their grand estate, possibly for one last time?

Admittedly, season 6 holds some bittersweet moments. We cannot be gladder that love finds its way into Edith's life again, and we hope it is Mr Pelham.

Nevertheless, it would be interesting to see how their romance plays out, as Edith inherits the printing press in London. Will she move to the country to be with Mr Pelham, or establish herself as a journalist? This would most definitely be one of the story lines the show creators will pursue.

In the clip, we see the Crawley family assemble in Church, perhaps for Mr Carson's wedding. If the trailer is anything to go by, the butler of Downton Abbey has the toughest time saying goodbye to his beloved job. But the show points to his future, and it comes with Mrs Hughes' companionship.

Much of the drama will take place in England in 1925, but we can expect the Crawleys to move to America. Throughout the series, almost everyone travels to the US. And if Earl Grantham's (Hugh Bonneville) purse strings are tightened, would he move to the East Coast along with his wife, Cora?

This seems to be a popular fan theory. Perhaps then we will see Branson and Sybbie re-unite with their family.

Indeed, that would be a lovely end. That is, if Mr Molsely and Baxtor marry; the Bates have a baby and if Thomas Barrow falls in love.

"Downton Abbey" Season 6 will premiere on Sunday, 20 September in the UK.
