As we reported back in November, Amy Brenneman is joining Reign. Now, we can offer a first look of her as the character of Marie de Guise.

On Reign Season 1 Episode 13, Marie will make an appearance at the castle to try to restore some order to Mary's life. 

In an interview with The Hollywood Reporter, Brenneman alleviated some fears for history buffs by sharing that Marie de Guise will remain a fairly true interpretation of the woman herself, despite the poetic license Reign has been taking.

"She's consistent with the historical figure, which was fun and interesting for me to know," Brenneman says. "She's a very strong woman, a very unusual woman for that time. Honestly her only similar peer is Catherine de Medici (Megan Follows). In addition to the rivalry, there's also real camaraderie and understanding." 

Expect a brief moment of mother daughter emotional bonding between Marie and Mary before she's down to business. 

Marie's main concern is Queen's Catherine's decision making based on Nostradamus' prophecies, which she finds ridiculous. 

It sounds like Brennaman's de Guise will be there to stir the pot and make a little trouble while trying to smooth the waters for her daughter. We can't wait to see this badass mama in action!
