POSSIBLE SPOILER INFO:
Hints from the cast say that the big event that will bring everyone back to Downton Abbey
is the 40th anniversary of Robert and Cora. The only cast member we
know we won’t see is Cousin Rose (Lily James), whose character moved to
New York.
ed speleers said in an interview that he didn’t even get a call yet so it’s safe to say he’s not in it either. (not that I’d have expected Fellowes to bring Jimmy back anyway. >_<)
