Following another twisted episode of The Secret Circle, how will this drama follow up next Thursday night?

With a slumber party, of course!

Look for the series to celebrate Valentine's Day via an all-girls sleepover... which quickly turns into a non-all-girls sleepover when Lee shows up, soon after Diana is actually given some Devil's Spirit by Melissa.

Elsewhere, Cassie will turn to both Adam and Jake after she finds herself haunted by the spirits of some seriously vengeful witches. That's never fun, is it? Check out the official CW promo for "Valentine" now.
