The "How to Get Away with Murder" mid-season premiere was explosive as some fans thought it would be. The riveting new episodes finally shed light on what happened the day after Sam's murder.

However, new reports suggest that apart from Annalise's and the interns' response to the killings, fans should watch out for the two new cast members joining this season.

In an interview with E!News, Viola Davis hinted that Marcia Gay Harden, who plays Sam's sister in the show, is a force to be reckoned with.

"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.
