In Season 2, Episode 20 of "Reign," "Fugitive," Francis will turn the world upside-down to catch Condé, but Mary will do everything in her power to stop him, reports Broadway World.

In Episode 19, Mary chose to side with Francis as England's threat intensified while Condé took a bold step to secure his alliance with Queen Elizabeth.

Condé slept with Mary. He has been fraternizing with France's enemy. Francis now has personal and political reasons for wanting to take Condé down. Though he is ailing, Francis musters the strength to launch an effort to catch him.

Meanwhile, Catherine, who harbors raging jealousy over Lola, will ask Narcisse to do something unforgivable, but will he? Narcisse has a soft spot for Lola, which Catherine may be testing with this demand. Fans will soon find out if Narcisse is using Catherine or if he has genuine feelings for her.

A good portion of the show will center on Greer and Leith's romance. Greer makes a choice that could place their relationship under the radar.

On April 16, Jonathan Keltz, who plays Leith, talked to TVLine about his character's relationship with Greer.

"We're the happy couple now!" Keltz said. "Leith has been trying to get back to that dream he and Greer had for themselves in the beginning, which they never thought was possible. Now, with the annulment, he believes so much that the dream is possible; the dream is real."

Greer is not the only woman in Leith's life. He's been tasked with protecting Princess Claude, an arrangement Keltz teased will be "rife with hilarity and wonderful, witty banter."

"Claude is somebody who, as we've seen over the past few episodes, is really a lovely person who's been shaped by people's perceptions of her," Keltz explained. "Being treated like a sociopath by her own mother really affected her, but the fact that she remains sensitive and vulnerable is truly a testament to her character."

We can't forget about Leith's involvement with the cardinal, which will test "how far [he's] willing to compromise his morals and his friendships and his place in French Court for this love."

Keltz warned fans to brace themselves for the final episodes of Season 2.

"There are some new people returning from our past, as well as some new people arriving," he said. "The very foundation of French Court, England, Scotland -- everything's about to change ... it's going to re-shape who's alive, who's not, who's here, who's not and what the show and French Court even are moving forward."

Lastly, Kenna is about to cross the line with General Renaude.
