I never loved you.

Its a chilling statement that left even Clarkson in awe as she said Adoras words.

And what happens [in between] is… she trails off and sighs dark as hell.

Below, the actress delves into what its been like playing Wind Gaps mercurial, frosty leading lady.

Adoras ability to charm the entire town is on full display in this latest episode set on Calhoun Day.

And I had to embrace the beautyandthe beast.

I had to embrace both sides, the dichotomy of this woman and many layers in between.

So it was an unexpected journey, even though I knew what was coming.

Was there one side that was easier to grasp?No.

The veneer was exhausting, and the monster, the beast is… [pauses] debilitating.

[Laughs]

When Adoras with Amma, is she the beauty or the beast?

This child will never grow up in her eyes.

Amma will always have pigtails and ponytails and the dollhouse.

Its a toxic love.

[Laughs] And some of the mostunusual… [Raises her arms] It isnota small tale.

And well go home and the next day we start again.

Now, Gillian had told younotto read the book, right?

How did that affect your performance?Yes, she did.

She liked that I only knew Adora in this script form.

I knew the story, but she said, Dont read the book.

At one point I just went, Oh,wow.

[Laughs]

What were they saying that struck you?Just her journey.

Its… Look, be careful what you wish for, but I love being challenged as an actor.

I want someone to take to the sky.

What has helped you think outside for Adora?

Its a weird thing.

But anyway, the clothes I wear and the heels, they definitely helped define this character.

Shes such a physical, external character… until the walls start dropping.
