Their shared son, Konstantin (Josh Heuston), is a testament to the strength of their bond.

He allows himself to be vulnerable only with Francesca.

You see him up close with all his flaws and insecurities when she is around, Tabu tellsEntertainment Weekly.

Of course, everything is a design with the Bene Gesserit, so there was some motivation.

But I think what makes it interesting is you’re left guessing, what could they have been?

Unfortunately, sometimes its easy come, easy go.

Francesca did not survive theDune: Prophecyseries finale and for that matter, neither did the Emperor.

It was very sad.

Its very sad for Francesca and Javicco, but I feel like it’s such a strong love story.

They couldn’t live with each other, but they literally died with each other.

“We love him, and we’re very sad about it,” Schapker said.

“Mark Strong was a joy to work with, just a tremendous actor and a tremendous human being.

I think his characterization of this particular Emperor was brilliant.

It was such a pleasure to watch him trace his arc across the season.

But yes, I think it’s safe to say that he’s dead.

But he will be missed, and he leaves a big power vacuum.”

But the question of who will fill that vacuum in the meantime remains to be answered.
