'The Secret Circle': Cassie Faces Her Dark Magic With Help From Diana's Grandmother (VIDEO)

Scared that she's unable to control the dark magic that dwells inside her, Cassie accepted the help of someone she barely knows on "The Secret Circle" (Thu., 9 p.m. EST On The CW). It helped that it was Diana's grandmother, and that Diana was confident that Kate would know how to help Cassie.

But things seemed a little fishy when Kate took her into the middle of the woods. There, rather than attempt to help Cassie harness her dark magic, or even free her from it completely, Kate instead used some magic of her own to knock Cassie out and then dump her in a pine box.

Adam and Diana managed to track her down, but it turned out Cassie didn't need their help. She erupted out of that box like a dark witch who knew full well what she was doing -- which of course she doesn't. But she's well on her way to harnessing this dark power that so frightens her. How powerful is she going to be?

Find out as "The Secret Circle" continues Thursday nights at 9 p.m. EST on The CW.
