Wow. Did you see either of those developments coming?

On this week's return episode of The Secret Circle, viewers witnessed one death and one surprising reveal. How will each affect next Thursday's installment, "Traitor?"

It will focus on a stolen crystal; an attempt to convince Isaac to change side; more problems for Cassie and her dark magic; Melissa and Adam pairing up; Diana reaching out to Charlies; and, according to the official CW synopsis, the coven visiting the "Creepiest Place on Earth."

Check out photos from Traitor now and then watch the following teaser:
