Kennedy, who plays Melissa, told MyFanbase that viewers will have a lot of questions.
"I feel like every time we turn a corner and find something out about Cassie and our parents' past, it raises even more questions," she said.
"The writers are doing a great job of keeping the viewers on their toes. I feel like the show is full of suspense, drama, romance and a great deal of mysteries yet to be solved."
Michael Graziadei and Sammi Rotibi recently signed up to appear in future episodes of The Secret Circle.
The show will return with a new episode on January 5 on The CW in the US. The series airs in the UK on Sky Living.
