I started watching TTP after seeing the "Amellsday" promo. The moment I saw Astrid, I thought, "Wow. She's just like Thea."
Her tone of voice, her inflections, and mostly the way she truns the corners of her mouth down and her dimples appear at the edges when she ends a sentence.
If I knoew how to use youtube, I'd make a comparison video and I could show you.
