"She is the one we have been waiting for. The one that can tip the balance between Good and Evil."” — Kate Meade to her son, Charles, about Cassie's powers.Cassie Blake, born March 28, 1995, is the main female character and protagonist of The Secret Circle. She is the daughter of Amelia Blake and John Blackwell, best friend and older paternal half-sister of Diana Meade, ex-girlfriend and best friend of Adam Conant and also a member of the Chance Harbor Circle.

Cassie was a happy, normal teenage girl until her mother Amelia died in what appeared to be a tragic accidental fire but not such as an accident. Orphaned and deeply saddened, Cassie moved in with her warm and loving grandmother Jane in the beautiful small town of Chance Harbor, Washington - the town her mother left so many years before - where the residents seems to know more about Cassie than she does about herself. As Cassie gets to know her high school classmates, including sweet-natured Diana, her handsome boyfriend Adam, brooding loner Nick, mean-girl Faye and her sidekick Melissa, strange and frightening things begin to happen. When her new friends explain that they are all descended from powerful witches, and they've been waiting for Cassie to join them and complete a new generation of the Secret Circle, Cassie refuses to believe them - until Adam shows her how to unlock her incredible magical powers. But it's not until Cassie discovers a message from her mother in an old leather-bound book of spells hidden in her mother's childhood bedroom, that she understands her true and dangerous destiny. What Cassie and the others don't yet know is that darker powers are at play, powers that might be linked to the adults in the town, including Diana's father and Faye's mother - and that Cassie's mother's death might not have been an accident. But the more time passes by, the more Cassie gets confident of herself and develops her incredible potential.

Cassie is a member of the Blake family and the Blackwell family.


Early lifeEdit

Cassie Blake was born on March 28, 1995 to Amelia Blake and John Blackwell. Shortly before Cassie's birth John betrayed Amelia by having an affair with Elizabeth Meade which resulted in Diana Meade being born less than a month later. John also summoned demons which resulted in Amelia leaving him prior to the Boatyard Fire. Sara Armstrong stated in the Witness flashback that Amelia would never forgive John for what he did to her and she said that Amelia helped Ethan in his plot to killed John which backfired. Later consumed by guilt and stripped of her magic, she later abandoned what was left her coven by moving to Los Angeles with Cassie. Amelia had to keep witchcraft and Cassie's magic legacy along with the truth about her father a secret from her daughter prior to her death in Pilot.

Cassie is stunned when a notoriously evil figure from her past shows up on her doorstep. However, her surprise quickly turns to suspicion when he asks her to return the medallion she found in the wreckage of the fire that killed their parents. Cassie storms off but is captured by Eben and his band of witch hunters. Jake offers to trade himself for Cassie's freedom and when Adam realizes they're in trouble he calls the Circle. Meanwhile, Faye and Diana are concerned when Melissa starts spending more time with Callum.

Cassie catches Blackwell sneaking around the abandoned house. After confiding in Adam, he tells her he knows Blackwell was looking for a device to drain witches' powers and clearly back to his old ways. Faye shows up at Lee's house to invite him to the school fundraiser, but is taken aback when Eva greets her at the door claiming to be Lee's girlfriend. Meanwhile, Melissa encourages Diana to date a normal guy and points her in the direction of a new, handsome guy in town. Dawn runs into Blackwell at the school but the reunion isn't quite what she expected.

Blackwell warns Cassie and Adam that their love may be destiny, but it's also a curse. He suggests they go visit her grandmother, Jane to find out if there is a spell to reverse it. Jane warns Cassie that someone in the Circle will die if the curse is awakened. Meanwhile, Eva starts stalking Faye and Charles makes his next move against Blackwell.

Jake gets a surprise visit from an old acquaintance named Samuel, a witch hunter, who has a message for Blackwell about Eben's surprising next move. Cassie intervenes, forces Samuel to reveal his news and is stunned to find out what Eben is trying to resurrect. Meanwhile, Diana is frustrated that keeping the secrets of who they are is building a barrier between her and Grant. Faye and Melissa agree to help out Adam at the Boathouse and in return get him to help them use their magic to enhance their love life.


In Crystal, Cassie finds out that Diana was her half sister because Royce, Jake's grandfather, said that his Crystal was hidden in a mine and he spelled it so that no Witch with Dark Magic can acess it. When Cassie and Jake got to the mine to rescue Adam and Melissa, Cassie started choking and couldn't go in, since she had Dark Magic. Later, Diana said that she couldn't help Melissa and Adam out of the mine either because she was choking as well, meaning that she has dark magic and is the other child of Blackwell in the Circle.

In Traitor , Cassie realized that her grandmother (Jane Blake) is dead, so she falls into sadness and anger believing the witch hunters had killed her grandmother. Adam tried to comfort her and she accidently kissed him, resulting her to be very sorry.While Cassie confronted John that she wants to kill the witch hunters now more than ever. At the Abandoned House, Faye and Jake brought some good news that they found a crystal, but its energy was drained out, but was stolen by the traitor later in the episode. This resulted Cassie, Diana,Jake and Faye into going the most creepiest place on earth-as Faye mentioned, but before that Jake wanted to asked about the witch who was working for Eben so he arranged a meeting with Issac so they came there first. Instead of Issac there, it was Ian who told Jake that Eben had killed Isaac because he had let the traitor escaped and informed him that he never met the traitor. Cassie then attacked Ian by sufficating him causing Diana and Jake to try and stop her, after that Ian critisized Jake and went away.When half the circle and Cassie arrived there, the creepiest place on Earth actually was an The Abandoned Carnival.
As the circle went in they were seperated into two groups; Faye with Jake and Cassie with Diana even though Diana wanted to go with Faye instead because she doesn't want to talk with Cassie about her being half-sister of Cassie, but Faye said she doesn't want to go with any of the dark magic super twins with her which changed Diana's mind of going with Faye. Cassie tried to talk with Diana that dark magic isn't that bad, but it can save people like she saved Diana during the time Luke almost killed Diana (Masked). When both Diana and Cassie heard a noise they ran there and saw the traitor.Cassie decided to kill the traitor, but Diana insisted not to so she just knock him down. They discovered the traitor was Nick who they believed to be dead. They then chased him saying they don't want to harm him, but just wanted the crystal which he dropped and ran away.


"I talked to Nick once before... he told me this blond girl moved next door into the Blake House; short, sad, but strong, a survivor. He admired her. I guess he was talking about you."
— Jake to Cassie about Nick's opinion on her.

Despite Cassie's independent and strong-willed persona, she is a very kind and loving young woman who cares deeply about her family and friends. When she uses dark magic she is seen with an evil look in her eyes.

At any rate, it seems grief mold her personality in more ways than one. First her mother died and the loss, along with the realization she will have to start doing things on her own, mae her tougher. Then her grandmother died and she channeled all the anger she felt against the witch hunters.

Powers and abilitiesEdit

"Just how powerful are you?"” — Diana Meade, after Cassie's Dark Magic was fully activated.

Cassie is one of the most powerful witches we have seen to date. What she doesn't have in formal training on witchcraft she makes up for it with raw power.

Her great potential was shown early in the series when she managed to subdue a storm neither Faye or Diana could stop, showing an affinity for Atmokinesis. When the entire Circle was once kidnapped and was about to be killed by Luke she was able to blow up one of Luke's Witch Cruids with a solid shout. Seconds after this, she set flame to Luke killing him, proving just how powerful her dark magic truly is as she activated its power through instinct alone and it was enough to overpower a barrier of ashwood, a special type of wood which renders most use of magic useless.

When Faye was being contacted directly by the residual energy of her dead grandfather, Cassie was the only one who could see the ilusions as well, indicating she has stronger magical senses than Jake, Adam, Diana. When Isaac tried to kidnap Cassie and deliver her to the council of Witch Hunters, he recognized the danger she poses on them shall her dark magic been unleashed on the boat and so he didn't pursue her when she escaped.

When Kate Meade buried her alive to test the limits of her powers by bringing her to the brink of death, Cassie's dark magic proved to be too powerful for the ritual to hold her and such it was proven that she is more powerful than an experienced Elder.

At the Fire and Ice Dance, Cassie proved to be highly resistant to external influences that seek to take away her powers, as shown when the Voodoo ritual Faye and Lee made failed to overpower her natural defenses. This ability was shown again when a potion with Lethe root designed to take away her feelings for Adam didn't work on her.

During Sacrifice, she fought against a demon and although she failed to defeat it she succeded in employing the use of Pyrokinesis. Cassie also repeatedly shows outstanding use of Telekinesis ranging from lifting heavy things and throw them to light weighted spears with greater precision. She also has considerable constrictive powers, as shown constantly when she have choke someone with dark magic. During Family, she succeded in overriding the command John Blackwell put on the Crystal Skull and used it to kill her father, albeit with the help of her sister Diana.

Cassie have also used Circle magic to great effect like when they toss around Zachary Larson with Aerokinesis and when she combined her powers with Jake to fend off witch hunter Simone. Aparently, she also has great potential to use Photokinesis, as displayed in Bound.

While her half-sister Diana also has Dark magic, Cassie has a stronger magical potential because she is also a Blake. In fact, if she would have the same amount of magical training as that of John Blackwell, it would be fairly possible that Cassie would be more powerful than Blackwell, but as she lacks years of training her father is still more powerful than her through experience. That was proven when Cassie couldn't kill the demon possessing Samuel despite exploiting a demon's weakness while Blackwell completely destroyed it

It is possible that she is the most powerful witch in her circle due to both her Blake and Blackwell bloodlines.
