Sunday night (Dec. 1), PBS aired a “Return to Downton Abbey” special, hosted by actress Susan Sarandon, which took a look back at the entire series so far and also offered some new clips and teases of the upcoming Season 4.

Check out these clips from PBS — above, the cast and creators tease what is coming up and frankly, they can’t say too much. But creator Julian Fellowes does say that the arc for Mary is about entertaining the notion that she can fall in love again. She’s obviously still very much in mourning for Matthew.

Below, the stars and designers drop some trivia about what you may not know about the show — like how they only use one room to represent all the bedrooms, or that the ladies’ wigs have names. Hee.

We’ve also got a gallery of pictures from Season 4 — there are no episode details, but the pictures themselves could be slightly spoilery, so view at your own risk.

The clips are delightful and are really making us excited for Season 4, which premieres Sunday, Jan. 5 at 8 p.m. ET/PT on PBS.
