Blood in the Water


Season 4 Episode
"Because I cannot have her blood on my hands. And I cannot let her go."
Queen Elizabeth


Mary makes a decision that will change the course of history -- forever shaping the fate of her nation, her crown, and her newborn son. Mary's perilous move for her survival causes the stunning realization that perhaps she is not the only one who may not survive. Meanwhile, Elizabeth steadies herself for war and will become the instigator in Mary's demise while later realizing she and Mary might be more similar than either thought.


Guard: If you have a baby that isn’t yours, you’ll hang, unless you cooperate.

Queen Catherine: Tell me, how is Mary?
Lord Narcisse: Struggling to maintain her throne.

Queen Catherine: This is Stéphane Narcisse, he's the Lord Chancellor of France. Stéphane, this is a witch that my pious daughter, Leeza, rounded up amongst other heretics.
Emanuelle: I didn’t care for her. Clearly, you didn’t either.

Emanuelle: Don't worry. Spain will still be a bother, but its queen won't be a problem much longer. Complications with her third child. A girl.

Emanuelle: Nicole is inches from the grave. She just doesn’t know it yet.
Queen Catherine: Then you'll have your money and your freedom.

Queen Catherine: Claude, this isn't your fault. Luc is gone, you are here, which means he abandoned you.

Princess Claude: I lost both the man I love and the man I could have loved.

King Darnley: My son you mean... My God, I think I left him somewhere!

Queen Catherine: Well, it’s not my usual form, but let me pay you how I planned.

Queen Elizabeth: I am England! And I need no one to save me! Not from Spain. Not from the Chaotic Church. Not from anyone. I am Elizabeth Tudor and I will bow to no man. I will face ever threat to my reign with sword in hand. And any who shall stand in my way shall fall.

Queen Catherine: I have always put my children first. I have done terrible things! I have always done it for their good. But are they worth it?
Francis was. A noble decent man. And a good king.

Emanuelle: The key to your survival, should you choose it, is your daughter, Margot. Blood will flow, but it won't be yours, if you have Margot at your side.

John Knox:Men will never willingly bow to the weaker sex.
Queen Mary: And they will suffer greatly for it.

Queen Elizabeth: Because I cannot have her blood on my hands. And I cannot let her go.

Queen Mary: I put my trust in you, my Lord.
