"Reign" Season 2 is set to return this fall with plenty of new conflicts and drama. As King Henry is dead, Francis and Mary will begin their reign as King and Queen of France.

"In the next season it will be really interesting to see how she [Mary] and Francis together handle being the king and queen of France," Laurie McCarthy, co-creator of "Reign," said to The Loop.

McCarthy has indicated that Season 2 will feature the historical violence between Protestants and Catholics. Francis and Mary will "find themselves as king and queen of a nation that's really on fire and an enormous part of that is going to be the Protestant/Catholic conflict," according to the co-creator.

In the final moments of "Reign" Season 1, Francis came to know about Lola giving birth to his child, outside the castle. He galloped away on his horse even after knowing that the plague is fast spreading in the villages outside the castle. McCarthy said that one can expect things to get "perilous" with the plague and it is going to feel "apocalyptic."

"There's going to be huge division between those who are privileged to survive and those who don't. It will be horrific and violent and chilling ...," McCarthy said. "The plague is going to change the landscape of our region of France and that Bash will be involved, as will Francis, with the aftermath of that."

The end scene of the final episode of Season 1 was Mary asking the guards to lower the gates, as Francis watched from the other side. It looks like Francis will return with Lola and their child and this is likely to make Mary feel jealous. McCarthy thinks that Mary will "fight her unease and fight her jealousy with every fiber of her body, but I think it's going to be a battle."

McCarthy, however, thinks that Bash and Kenna's love will last. But, the horror will continue to touch Bash in Season 2. And, Francis will come to lean on Bash. McCarthy indicated that the relationship between Francis and Bash will continue to be complex.

"Francis really loves his brother, and Bash really loves Francis but their stations will always pull them apart. At the core of the series, I really see that brotherly connection as a deep and true friendship --it's one of the running love stories of the series, the love between the brothers and the love for Mary and her friends," McCarthy said to The Loop.
