WandaVision

Agatha Harkness:
Wanda. You've never been up against another witch before. Don't you know there's a whole chapter dedicated to you in the Darkhold? That's the book of the damned! [Agatha materializes the Darkhold] "The Scarlet Witch is not born, she is forged. She has no coven, nor need of incantations."

Wanda Maximoff:
I'm not a witch! I don't cast spells! NO ONE TAUGHT ME MAGIC!

Agatha Harkness:
Your power exceeds that of the Sorcerer Supreme. It's your destiny to destroy the world.

Wanda Maximoff:
[throws up her arms in exasperation] I'm not what you say I am!

Agatha Harkness:
Oh really?
