Tonight on The Secret Circle, a demon will take over Melissa's mind and force her to manipulate the coven into making a drastic decision.

Is that enough of a tease for you?

In the following preview, producer Andrew Miller says "Slither" will pick up where last week's tremendous episode concluded, as Melissa is in bed with Nick, but is acting like anyone but herself. Expect that behavior to continue through the hour, as evidenced by a few clips below.
