Last week on The Secret Circle, viewers learned that Diana (Shelley Hennig) is the second Blackwell child. Hennig only learned that Diana was Cassie’s (Britt Robertson) half-sister a few days before the episode was shot. “I was shocked and I kept thinking, ‘Well, the scripts change up until the day of,’ so I didn’t get my hopes up until I was actually shooting the episode,” she says. “We all wanted it. It was a cool twist for any of us. But for me, I just thought that it would explain Diana’s connection with Cassie all along, and the fact that the first person she’d go to when her and Adam broke up was Cassie, the girl who basically got between the two of them. I remember shooting that going, ‘Ohmygod, never in a million years would I go to the girl who got in the way to cry on her shoulder.’ So it just totally makes sense now, in my mind.” So where do we go from here?
Moral Diana, who doesn’t like the idea of being from a dark magic bloodline, will need more proof than not being able to get into the spelled mine last episode, so she’ll confront her father, Charles (Gale Harold). “It doesn’t go over very well. Diana’s whole life has been a lie. That’s what she finds out and what she has to deal with. It’s not a pretty sight,” Hennig says. But it does give Harold some great scenes. “He goes in so many different directions in the next two episodes. He definitely has a lot going on, more than just the normal ‘I want my power back.’ He has a lot more obstacles to deal with.”
When will the rest of the Circle find out she’s the other Blackwell child? “She finds out that John Blackwell’s intentions are not pure ones. They’re not the same as the Circle’s. That’s a good time to tell them, when she warns them about him,” Hennig says. “Both Diana and Cassie find out more about his intentions in the prom episode, and it leaves Cassie to deal with some really devastating stuff for her because she’s gotten close to John Blackwell. Diana’s just there to say, ‘He’s horrible. We cannot trust this guy.’ It’s the battle of do we trust him, do we not? Do we need him to get the crystals even if we don’t trust him? Once Cassie expresses to Diana that she needs Diana, because they have the same power, to get more information to get the crystal, it puts Diana back in her leader position. Diana’s like, ‘You need me, which means I can lay down the rules. And we’re gonna do things my way.’ That’s what you’ll see happen in the next two episodes.” Something else that happens: Grant (Tim Phillips), who Diana left at the dock last episode, resurfaces for the prom episode. “He’s still in the mix, which makes things even more difficult for Diana. She’ll have to fight to keep Grant, but she still can’t tell him why she’s… so weird,” Hennig laughs.
The synopsis for the May 10 season finale has been released, and reveals that Blackwell tells Cassie and Diana that the only way to stop the Witch Hunters is to use their Balcoin blood to unleash the Crystal Skull. Diana is reluctant, but Cassie convinces her it’s the only way to help Faye (Phoebe Tonkin), who’s been attacked. “If it’s gonna save their lives, and it’s the only option, then yeah, Diana has to do it,” Hennig says. “But she can also take precautions and watch Cassie to make sure Cassie doesn’t fall into something larger than herself with John Blackwell’s power over her and Diana. So Diana’s very weary, but you know, you have to do what you have to do.”
We had one more question for Hennig: The show, which today launched a new iPhone and iPad app, seems to be pairing Adam (Thomas Dekker) and Melissa (Jessica Parker Kennedy) a lot lately. Is there something brewing there, and how would Diana feel about it? “I’m not sure. A lot of times, we play it regardless if it’s written or not, so we don’t know if they’re gonna edit it out. I’d imagine that Thomas and Jessica played around with that and explore it. But we don’t know what it’s gonna look when it’s edited,” she says. “But I think that’d be a cool twist. And I think at this point, Diana wants away from everything in her past. So I’m not sure it’ll directly affect her, because I think she’d just focus on Grant and maybe moving forward with him. Unless Grant screws her over. Then maybe Adam will be there when she falls.”
