New "How to Get Away with Murder" spoilers warn fans to watch out for two new cast members that will change the pace of the hit TV series.

In the previous episode, Sam's sister played by Marcia Gay Harden, was introudced. And judging by the overall feel of the episode, (and Annalise's expression) it could be implied that her character will be a bad news for Annalise and her interns.

In a recent interview with E!News, Viola Davis who plays Annalise in the show, shared the why Annalise and her sister-in-law never got along.

"It's a woman who just never really embraced her in the family. You'll see that relationship be very contentious because it's a woman who just never accepted me. She never saw me," she said.

"She loved Sam's ex-wife much more than she loved me. She was more of an acceptable mate for Sam. But it was never spoken, of course, so you'll see a lot of butting heads because there's a hesitance on Hannah's part to admit she never accepted me."

"She suspects that I killed Sam. It gets more complicated as the episodes go along. I know that she's willing to do anything," Davis continued.

Apart from Harden, Emmy Award winning actress Cecily Tyson is also slated to join the cast. And just like Sam's sister, Tyson's role in "How to Get Away with Murder" will definitely change the pace of the show.

"I think that it will surprise you in simple ways. I think it will be touching in unusual ways. And I think it will still be salacious and intriguing. And look out for Miss Tyson-look out for the force that is Miss Cecily Tyson," Davis teased in an interview with TIME.
