[Warning: This article contains major spoilers of “How To Get Away With Murder” Season 3, episodes 14 and 15.]

“How To Get Away With Murder” finally revealed who killed Wes (Alfred Enoch) in its explosive Season 3 finale. It was Laurel’s (Karla Souza) father Jorge Castillo (Esai Morales) that ordered a family friend, Dominic (Nicholas Gonzalez), to kill her daughter’s boyfriend and set Annalise Keating’s (Viola Davis) house on fire.

Of course, Laurel, Annalise, Bonnie (Liza Weil), Frank (Charlie Weber) and the rest of the Keating 4 don’t know Wes’ real killer. They only know that Assistant District Attorney Todd Denver (Benito Martinez) had a hand in his murder. They still suspect the Mahoneys somehow killed the African-American law student.

In fact, Laurel almost pulled a gun on Charles Mahoney (Wilson Bethel) but was stopped by Dominic in the nick of time. So, what’s next for Laurel and Annalise’s team in Season 4 of the ABC series?

For starters, we will get to know more about the Castillo family. We still don’t know why Jorge ordered Wes’ death. “Her [Laurel’s] world is crumbling in,” Souza told TVLine in an interview, “but I do think there’s a lot of fight left in Laurel. She’s going to want to come to the end of avenging Wes’ death and finding out what really happened. We’re definitely going to dive into Laurel’s family in Season 4.”

Dominic and Laurel’s relationship will also be explored. Are the two more like brothers and sisters or were they share a romantic relationship at some point in time?

Needless to say, “How To Get Away With Murder” Season 4 will reveal why Laurel’s father killed Wes. “I think they’re going to humanize my father,” Souza told Entertainment Weekly, “so we’re going to find out a real reason why he decided to kill Wes, but I do think it has to be rooted in something rather than just for the sake of it.”

The show’s executive producer, Pete Nowalk, told EW that the series will also touch upon the reason that Dominic killed Wes for Jorge. We will get to see more of Dominic and his relationship with Laurel’s father in the upcoming season.

“How To Get Away With Murder” Season 4 is expected to air sometime this fall on ABC.
