“Cassie Blake is not the only the only child of Blackwell in the circle.”

The Secret Circle is probably one of my favorite freshmen shows of the fall. Its mid-season finale kept me on the edge of my seat. That’s how you lead a show into a hiatus, you keep the fans guessing giving them the most nerve-wrecking cliffhangers. (You hear that, Gossip Girl?)

The moment the episode ended, my mind started wandering in all sorts of directions. Who’s the other witch from the circle who has dark magic? Who is Cassie Blake’s sibling? Could it be a brother? Or is it a sister?

The only possibilities are the members of the circle, so: Adam, Jake, Diana, Faye, or Melissa.

I would definitely eliminate Jake and Adam. I’m guessing the writers aren’t going to tackle incest on the show; they both have feelings for Cassie and both have already kissed her. (It’s the CW not HBO) Plus, Ethan, Adam’s dad, always tells him that he and Cassie are meant to be together which I think eliminates him by default. If it does turn out to be Jake, though, I’m going to hate this show forever. They can’t break my shipping heart like that. (Okay, not forever. I don’t think I can ever quit TSC)

So that leaves Melissa, Diana, and Faye.

I, also, do not think Melissa is the other dark witch. It would simply add nothing to the plot. And if she really is in fact Cassie’s sister, I think it would be a waste of a cliffhanger; she was barely even mentioned in the episode. (They should really give her a storyline though, it’s getting sad seeing her either in the background or not even in the episode at all)

The two left? Faye and Diana. And I think it would be plausible if either one of them is Cassie’s sister. (Kevin Williamson, the creator of the show, is also an executive producer on TVD. Does it ring a bell? Siblings fighting over the one person they love?)

Diana has been very peaceful through the first half of the season; she’s the leader who follows the rules and never crosses the line. And in the whole Cassie/Adam/Diana triangle, she’s the victim. So giving her a dark side would be an interesting twist and would definitely complicate things more between the three of them.

However, I’m almost certain that Faye has dark magic within her:

a) There’s A LOT of competition between Cassie and Faye, and the writers did say we’re going to see a lot of that in the second half. Sibling Rivalry?

b) Before the circle was bounded, Faye did a lot of “dark magic”. She threw Sally Mathews off the dock, she burned Cassie’s car, and she created an epic thunderstorm on her own. (However, after the circle was bound, she was no longer magic without the circle, Cassie can.)

c) Apparently, and according to Cassie’s granny, Faye’s mom was obsessed with John Black, Cassie’s father. Maybe she cheated with him and got pregnant with Faye? I wouldn’t rule that out at all. 

That said, the writers aren’t known for being predictable or for giving signs about what they’re planning on doing next. They did kill off Nick, after all, when we didn’t even see it coming. I guess we’re going to have to wait till the second-half of the season (the show is returning January 5) to find out.

Who do you guys think it is?
