Reign season 4: Season Finale, who did not survive the final episode?

Reign’s Final Series has unfortunately caused some casualties … Who has not survived the final episode of the CW’s historical series?
While in episode 15 of Reign’s Season 4, Mary became Mom , the Queen of Scotland bowed out last night in the final episode of the CW’s historic series. This Series Finale was particularly moving as one would expect. If we hoped for a happy ending for our three favorite Queens, Mary, Catherine and Elizabeth, this last episode of Reign unfortunately caused some victims. But then who did not survive the Series Finale? Well first of all, Nicole, the young woman for whom Henry and Charles were fighting was poisoned . Catherine had asked for help from a witch in order to eliminate the one that divided her two sons. Nicole was a threat to the future of France and had to be sacrificed. But Reign ‘s Final Series was also fatal to two other characters.
Darnley had become completely mad and threatened Mary’s throne in Season 4 of Reign . If she had tried to protect him, the Queen finally asked Bothwell to kill her husband . If Darnley survived an explosion, his rival managed to assassinate him with his own hands … And this of course was fatal to poor Mary who also found herself in prison. We believed it to the end! It was said that Elizabeth was finally going to pardon her, that Bash would come to save her or that her son could avoid the execution … But 21 years later, Elizabeth ordered that her cousin be executed. James, the son of Mary, had to choose between saving his mother or his country … To honor all the sacrifices of Mary, He had no choice but to choose the future of Scotland … Mary was therefore decapitated, so the series will have followed the story and has not chosen an alternative end. While waiting to discover new information on this Series Finale, discover also where we could find Katherine Heigl, Candice King or Adelaide Kane in the autumn. And you, did you think Mary could be saved in Reign’s season 4?
