The next episode of Reign premiering on Thursday night will feature vicious threats between Mary and Catherine.

Catherine Attempts To Destroy Bash?

The episode titled Inquisition has a scene with Mary and Catherine lashing out at each other over Bash. Mary brings out her confident side against the evil Catherine who makes an attempt to destroy Bash. It appears that if Mary wins her battle to save Bash, then Catherine will be punished with beheading. But it turns out that Bash could receive his own type of punishment as well after a baby makes a special appearance.

"If Henry can cut off my head based on rumors he creates himself, imagine what would happen to Bash with actual evidence?" Catherine says. "One look at that baby and Bash's enemies will say 'Where there's smoke, there's fire.'"

Mary and Bash's Relationship Gets Hotter?

Bash could be taken out of the throne for this and Mary could lose her alliance, according to Catherine.

With Catherine's threat, Mary reveals that it would be hard for Catherine to destroy her and Bash if she does indeed receive a beheading. This could lead into a deadly battle of who will destroy who first.

"You can help Henry trip me into my grave," Catherine tells Mary. "Which one of us will crush the other first?"

Mary keeps up with her dangerous side and gives a future message to Catherine.

"When the ax falls, I will be there," Mary says. "With Bash- the next King of France."

Reign airs on Thursdays at 9 p.m. on The CW.
