"Reign" Season 4 is speculated to see one character going insane. The news came directly from Adelaide Kane who plays as Queen Mary. Below are additional details on what await fans when the last season of the popular historical drama returns.

A report by Christian Post detailed Kane's interview with French Melty translated and posted on Tumblr where the actress said that a cast will fall sick in the new season. She refused to name the character but this character's illness will make him or her crazy. Interesting, right? But fans need to wait until the new episodes air to figure out who among the casts will go insane.

Though the forthcoming season is expected to see someone getting crazy, Kane spilled that there would be lesser deaths this season compared to Season 3. She also teased that Queen Mary will marry for the third time and will give birth to the future King James. That said, fans will get to meet her second and third husband in addition to her baby boy, which is an exciting part of the show for the actress as she apparently likes babies.

Kane also did not forget to spill that Will Kemp will be playing as her second husband Lord Darnley. She revealed that Kemp was awesome in his role but their relationship in the show is problematic. The actress also revealed that there are more new characters in the series and more storyline to explore.

However, it was already established earlier that Season 4 will be the last of the show. "Reign" will no longer be renewed for a fifth season, unfortunately. But given the time the production team had to wrap up the storyline, fans may expect a well-written conclusion.

"Reign" Season 4 air date is set on Feb. 12. It will premiere on Netflix UK according to TVWise. See the trailer below.
