Thank God Queen Mary (Adelaide Kane) wasn’t assassinated in the last episode of CW’s “Reign.” Unfortunately, the devious John Knox (Jonathan Goad) ensured that someone close to the Scottish queen once again paid the price for her.

In Season 4, episode 10, Knox colluded with Emily (Claire Hunter) and made her give false information to Mary’s half-brother James (Dan Jeannotte) that a prominent Protestant was going to assassinate her. The so-called assassination plot was a ruse to get Mary and James to kill this prominent Protestant.

Worried about the Protestants knocking on her door and Scotland going into civil war, the Queen of Scots decided to let James take the fall for the Protestant’s murder. The poor man was stripped of his titles and lands and forced to leave the country. Worse still, his absence delivered a serious blow to his budding romance with Greer (Celina Sinden).

Meanwhile, in England, Queen Elizabeth (Rachel Skarsten) celebrated her birthday and searched for a Catholic suitor to marry. Unfortunately, she is in love with Gideon Blackburn (Ben Geurens)

In France, Henri (Nick Slater), King Charles’ (Spencer MacPherson) younger brother, set his sights on the throne.

What will happen next on “Reign”?

Mary will launch a coup against her cousin in Season 4, episode 11, according to the synopsis on TVGuide. She does this with the help of her husband Lord Darnley (Will Kemp). Unfortunately, Darnley and Mary are at odds as they put their plan to seize England into action.

The promo of the episode shows Darnley informing his wife that their marriage has put pressure on the English queen to take a husband. They need to strike before Elizabeth announces her engagement. And it looks like she has found someone to tie the knot.

Meanwhile, in England, Gideon, who once loved Mary, shockingly tells his lover that as long as Mary is alive, Catholics will want her on the English throne. This seems disconcerting to watch since Gideon was once madly in love with Mary. Indeed, he even murdered a messenger for her. What is going on with this Englishman?

With the rivalry between Mary and her cousin strengthening, the Queen of Scots turns to her lover Lord Bothwell (Adam Croasdell) for support. The handsome ponytailed noble is quick to offer her support, comfort and unconditional love. With James gone and Greer resenting her for taking him away, she needs all the support she can get.

In England, the synopsis teases that, although Elizabeth may have a Catholic suitor, she is still conflicted about her feelings for Gideon.

Back in France, Catherine’s (Megan Follows) son Henri attempts to take the throne from his elder brother with the help of Spain and the cunning Lord Narcisse (Craig Parker). Will Leesa (Anastasia Phillips) have her way and put Henri on the throne? History tells us that Henri did take the throne. It remains to be seen whether “Reign” will follow what happened in real life or take some liberties.

“Reign” Season 4 airs Fridays at 9 p.m. EDT on The CW.
