Sunday night was a night of transition for the fans of PBS's British-American drama hit Downton Abbey. 

With Season three of the show now at a close in the U.S., its fourth installment is set to hit televisions overseas in the U.K. in just a little over six months and is currently in production. Now that Downton's American loyalists are all caught up, the scoop on what's to come will surely not be as big of a secret.

Carter reports that Rose's return will be paving the way for a pair of surprise characters, who will have a full grasp on the obvious change that's occurring in terms of the British society.

Also, Edith will be looking to develop her own independence as a woman, as actress Laura Carmichael already made the suggestion that it should serve as a theme that will more than certainly transition into the next season.

Tom Branson will reportedly continue to wear his heart on his sleeve in his quest to woo Sybil. The respective declaration will supposedly leave "a significant impression on him for months to come."

In an attempt to minimize premature Downton Abbey chatter, series standout Hugh Bonneville, who plays the part of Robert Crawley, recently responded to Twitter fans looking to pry spoilers out of him for the upcoming season.

"V sorry but I won't comment on past or future storylines of#DowntonAbbey.  Some tweeps are still on S1 #nospoilers."

Taking place in the fictional Yorkshire country estate of Downton Abbey, the popular series chronicles the lives of the aristocratic Crawley family after the Edwardian era and centers on historic events during that respective time period. 

Downton Abbey is set to return at some point in the fall with Season 4.  Information on the upcoming season will be posted as it's revealed.
