Such a dilemma.
So, where is the show going with this?
Thanks to this newly released teaser for season 5, fans of the acclaimed British period drama can get a glimpse of what's to come – and seemingly without spoilers.
The 20-second clip, released by ITV in the U.K., leaves much to the imagination, but promises that life for the Crawley clan won't be the same this season.
"The nature of life is not permanence, but flux," the butler Carson (Jim Carter), who serves as narrator, says in the clip. "Things are changing."
And where will that leave Mary?
Season 5 is due to premiere in the U.K. this fall, followed by a showing in the U.S.
