Promotional photos for the first season finale of Reign

The CW has released some preview images and a synopsis for the May 15 season finale of Reign.

Here is the official description for the episode, which is called “Slaughter of Innocence.”

FRANCIS AND MARY TAKE CHARGE, MAKING BRUTAL CHOICES THAT WILL CHANGE THE FATE OF FRANCE — When the King’s (Alan Van Sprang) madness and cruelty reaches a fevered pitch, Mary (Adelaide Kane) and Francis (Toby Regbo) take action. Their choices could change the course of history, but an unforeseen terror brewing in the woods could cost them, and their friends, everything. Mary makes a drastic decision when she learns Lola (Anna Popplewell) is going through a life-threatening labor at a location outside of the castle. Megan Follows, Torrance Coombs, Caitlin Stasey and Celina Sinden also star. David Frazee directed the episode written by Laurie McCarthy and Doris Egan (#122).

The show has already been renewed for Season 2 so this is definitely not the end of Mary’s story.
