“How to Get Away With Murder” Season 4 is about to get even more exciting now that Viola Davis’ husband, Julius Tennon, has been cast in an undisclosed guest-starring role.

According to Deadline, Tennon has so far been booked for only one episode. Will his character be a friend or foe to Annalise Keating (Davis) and the Keating 5? Is he a new lover, a former lover or a long-lost relative? For now, fans will have to patiently wait before getting any answers.

Tennon has already appeared in several series on CBS, including “Laws of Chance” and “The Architect.” Tennon also co-founded JuVee Productions with Davis, a company that produces economical and high-quality films that are diverse and character-driven. Through JuVee, Tennon has produced films such as “Custody” and “Lila & Eve.”

Tennon will be joining “NYPD Blue” alum Jimmy Smits in “How to Get Away With Murder” next season. The Hollywood Reporter said that Smit has booked a major recurring role and will be playing a prominent figure in the life of Annalise. His character will also have an integral role in the fourth season mystery.

Meanwhile, one of the highlights next season will be the blossoming (or crumbling) relationship of Michaela Pratt (Aja Naomi King) and Asher Millstone (Matt McGorry). Michaela surprised fans, including herself, when she said “I love you” to Asher last season. When Season 1 started, nobody expected Michaela would end up falling for Asher. But now, they became the couple everybody is rooting for.

But given the death of Wes Gibbons (Alfred Enoch), the two might find themselves in an emotional disconnect moving forward. “Michaela said I love you and I don’t know how she’s going to feel about that once all the trauma has died down at that moment,” executive producer Pete Nowalk told Entertainment Weekly.

Like Michaela, the rest of the Keating 5 won’t fare well, and they are going to be reassessing their priorities and future now that their friend and classmate is gone.
