Louise Ellis is one of the new characters introduced in Season 4 since its debut. She was written into the episodes flawlessly and immediately jumped on a storyline with Victoria Grayson. With everyone hating on Victoria, the addition of Louise trying to take her down garnered instant love and affection from the "Revenge" fans.

At the beginning of Season 4, it was really hard to tell what Louise's agenda was. Was she trying to take down Victoria? Or did she really like Victoria to be her mother? Apparently, Louise had big problems at home with her mother.

Just before winter break started, Louise formed a friendship with Nolan, which was actually quite surprising. And from there, Louise's story was taken further. Her mother, Penelope Ellis was introduced and for sure, no one likes Penelope. It's not only because fans have come to love Louise throughout the episodes, but it's more of because Penelope is the woman everybody loves to hate and see go down.

Carolyn Hennesy, the actress who plays Penelope to perfection, spilled a couple of details about her character, the story behind her and Louise and how long she'll be sticking around.

"She's is even more of a monster in real life [than in Louise's hallucinations]. She's a delightful southern pecan praline with a worm in the middle...She's nothing but sweetness and pearls and concern when there's someone in the room other than her daughter, but when she's alone with Louise, she's nothing but an impaling pole," Hennesy revealed to TV Line.

Hennesy continued to share that she actually loves the role and playing a villain is her specialty. "It is my wheelhouse," she exclaimed.

Hennesy also talked about her character's relationship with Louise and said that there will be "atomic bombs" dropped regarding the storyline. But what about her situation with Nolan? Nolan and Louise already took control of Penelope's money and she guaranteed and Penelope will take that back. After all, "it is all about the money," she admits.

So, how long will Penelope stay in the Hamptons and stir trouble for Louise, Nolan and Emily? Hennesy confesses that she wants to stay longer.

"I want her there forever, too! It has thus far been a five-episode arc, of which we've seen four. Five comes up on Sunday, so we'll see. Whatever happens, if it doesn't go Penelope's way, I'm hoping she doesn't take it lying down. She's capable of much more than we've even seen," she said.

Get ready to see the Ellis' family add drama to "Revenge" Season 4 on Jan. 25.
