Fans of the hit Lifetime series "Witches of East End" have already seen a lot in the show's six episodes, but it seems like the real drama is only starting to unfold. The upcoming episode 7 will see a number of twists and turns, International Business Times reports.

The synopsis of the seventh episode entitled, "Art of Darkness" was recently revealed. The summary assures that viewers will see a new character paying a visit to the Beauchamp family.

Tarkoff, the character played by James Marsters, is described as "an old family friend," who has his eyes on Joanna and Frederick. The promo for the upcoming episode showed Tarkoff handing a suspicious potion to Frederick.

"You will prepare this potion then slip it into mother's drink," Trakoff tells Frederick.

"You want me to kill her?" he asks.

The last scenes of the previous episode revealed that Frederick remained loyal to his grandfather. His king branding started glowing after saving Aunt Wendy and Ingrid from the blue creature. Frederick dropped to the bathroom floor in pain, apologizing to his grandfather for "letting him down."

The episode ended with Frederick saying, "I'll find another way. I promise, grandfather. I promise." This has left fans wondering that Aunt Wendy's intuitions about could be very well true.

Meanwhile, it was also revealed that Ingrid will be telling her sister Freya about her desire to date Dash. While Dash and Ingrid have both helped save each other on different circumstances, nobody knows whether his intentions are sincere. It can be remembered that while he was suffering from Mandragora poisoning, he wished pain for "all the Beauchamp women."

Moving on, Killian is also reportedly growing doubtful about Eva. In the promo, Killian says that he knows what Eva is doing to her. "You need to calm down," she replies. Killian, obviously angry, answers "I'm not going to calm down."

After the scene, Eva is seen splattering blood on Killian's face and he begins to shout in pain.

The new season of "Witches of East End" premiered last July 6. Its episode 7, "Art of Darkness" airs on Aug. 24, Sunday, at 9PM.
