'How To Get Away With Murder': The Sexy 'Incest' Brother Doesn't Know If He's This Season's Killer

Kendrick Sampson reveals his thoughts on Caleb, killers, and of course, Viola Davis.

When you watch "How to Get Away With Murder" every week, do you spend half of the episode's runtime leaning over to tell your friend, spouse, sibling, etc. that Wes (Alfie Enoch) it totally guilty, or Asher (Matt McGorry) knows more than he's saying? Well, as it turns out, you're in very good company -- because even one-half of this season's possibly incestuous (psh, like we trust that virginity test) sibling duo, Kendrick Sampson, doesn't know who killed his billionaire parents at this point.

"I have so many theories," Sampson told MTV News over the phone. "I share them with everybody, and the writers are obviously very coy and they say, ‘Maybe, maybe! That’s a good theory.’ I’ll tell them to Viola and she’ll say, ‘No, absolutely not.’ Everybody always has their opinions."

But opinions like that are just to be expected on the roller coaster ride that is a show like "Murder," where, according to Sampson, the writers work around-the-clock to ensure the the drama remains as juicy as ever -- even if it means baffling the show's actors at the last minute.

"I’m sure that the creator and the writers have a good idea of what they want, but as the writing progresses and they hash out details, they completely change it," Sampson continued. "Sometimes we get a script, and we don’t realize that they made a minor change on a revision the next day... and it changes the complete story. It might be something really small, but it completely changes everything. It’s a fluid process, and we don’t know from day to day what’s going to happen."

In order to stay focused on bringing Caleb's story to life in a believable way throughout all of these madcap twists and turns, Sampson says he sticks to what's at the heart of his character -- though, like us, he thinks that that heart is very capable of doing terrible, terrible things.

"He’s really strong-willed and protective of his sister... I do think he’s guilty of something," Sampson said. "I just don’t know what. He’s hiding something, I just don’t know if he’s specifically guilty of the murder, or which murder. I play the guilt of hiding something, and the protective nature that he has, and that passion that he has to defend himself and his sister, and I think that’s enough to make people believe that he may have done something, or may have not."

Of course, Sampson acknowledges that part of the appeal of what makes Caleb and Catherine seem so innately devious -- and part of the reason why we all want to believe that they're guilty -- is because they're so absurdly rich and powerful. Add "potentially incestuous" to that mix, and you have the stuff that Shonda Thursday dreams are made of.

"Who wouldn’t want to play the adopted wealthy son of a billionaire couple, who is accused of torturing and killing them?" Sampson said. "I think anything that is that far removed from the norm, people are fascinated with. Everyone has a desire pop in their head to get someone back, like ‘Ah, I’ll hurt you,’ but they don’t really do it. The people that actually go out and do those types of things, we’re fascinated with. Their psyche; and what drives them to actually follow through with the act, the crazy act, the most extreme one."

This includes Sampson's friends, who have apparently all been saying to him "I know you're sleeping with your sister" since the premiere of Season 2. ("As long as people don’t think I’m sleeping with my [real] sister, I’m good.") But all incest jokes and ridiculous plot theories -- theories that could very likely become a reality -- aside, Sampson is just grateful to be part of a diverse and dynamic cast on a well-written show, during a time when increasing the number of voices we hear onscreen is a major cultural talking point.

"I feel privileged and grateful," he said. "I loved [Davis'] Emmy’s speech. I don’t think people realize how monumental that was... they know that a black woman winning Lead Actress in a Television Series is a big deal, but I don’t think people take into account that she's not only a black woman, but a dark-skinned black woman, with beautiful black features. She’s not a European version of what people think is beautiful. She is a beautiful black woman -- middle aged, sexualized, powerful, educated... that’s just something that you don’t see on TV that much, and you don’t see it as the lead, ever."

Thank gosh for 2015, y'all... and of course, for murder.
