Heads may be rolling in episode 11 of “Reign.” The CW’s hot new drama continues to deliver jaw-dropping moments on Thursday, when “Inquisition” airs.

Last time viewers left off, Mary and Bash worked together to hide his family’s dark pagan past in an effort to keep their plans of marriage on track. Unfortunately for the pair, Queen Catherine is bent on keeping Francis as the next king of France … and has shown that she has no problem with permanently eliminating Bash and Mary.

Practically everyone has threatened Queen Catherine, and it looks like her evil plotting will catch up to her in episode 11. According to the leaked synopsis for “Inquisition,” King Henry will be accusing Queen Catherine of not only treason ... but adultery. 

The adultery claim is pretty funny coming from King Henry – who has had many, MANY mistresses – but “Reign” executive producer Laurie McCarthy teased that the queen hasn’t been that innocent when it comes to other lovers.

“You’ll find out that Catherine’s love life is perhaps richer than any of us would have guessed,” McCarthy revealed to TVLine.

How scandalous!

Queen Catherine’s not one to go down without a fight, though, and King Henry’s attack will lead her to take drastic measures to save her life – including exposing Bash’s “dark past.” It’ll be up to Mary and Bash to “go on a quest to expose an even more deadly secret from Catherine’s past.”

And with the “rich” love life in mind, is it possible that Francis is not actually King Henry’s son? Now that would definitely make heads roll!

“Inquisition” will be action-packed as the love triangle of Mary, Bash and Francis becomes more complicated, but that’s not the only thing that fans can look forward to. Since the premiere, “Reign” viewers have been questioning the mystery behind the hooded castle lurker, Clarissa. And now they’ll finally get some answers! The synopsis teases that Nostradamus (who must be alive after Clarissa’s attack on him) will reveal the truth about “the castle ghost” and that the truth will shock everyone.

Episode 11 of “Reign” will air on the CW on Thursday at 9 p.m. EST. What do you think will happen in “Inquisition?” Are you excited to find out more about Clarissa? Let us know your thoughts in the comments section or send a tweet to @AmandaTVScoop.
