Wes Gibbons (Alfred Enoch) has sadly been killed off in “How to Get Away With Murder,” but that does not mean fans have seen or heard the last of him.

His girlfriend Laurel Castillo (Karla Souza) will be making a huge decision about their unborn baby when the show returns for its fourth season, and sooner or later, she will begin suspecting her father for Wes’ murder.

“Guilt will definitely be the first emotion, but she’s also such a doer that she would want to get revenge,” executive producer Pete Nowalk told Entertainment Weekly.

Nowalk added that Laurel’s actions will trigger the fourth season mystery, which he guaranteed would be “bonkers.” “Our new season starts with the story line and it just goes gangbusters from there. The question is, Does Laurel know or does she not know? We’re going to find out an answer to that soon, and it’s going to set us off on this crash course that’s going to lead to our midseason question/flash-forward, which is bonkers,” he said.

Nowalk already told TV Line earlier that fans will get to delve in Laurel’s backstory this season and find out why her father would order such a cruel act.

“This is the perfect way to reveal more of where [Laurel] comes from,” Nowalk said. “It will make a lot of sense why he ordered Wes to be killed. It’s fun to dig more into what Laurel’s backstory is and create a mystery around her family.”

As to the others, Nowalk said they will also be dealing with Wes’ murder in their own way. Annalise Keating (Viola Davis) feels responsible for his death, so she is not in a good place. However, Annalise is not a woman who refuses to stay down for long.

The Keating 5, on the other hand, are “trying to be happy and trying to make the most of their lives,” said Nowalk. “Wes’ death reverberates for each of them, and they all react in a different way this season…and what’s fun is that each of the kids has a very different reaction to that, and it starts the arc of the season.”

“How to Get Away with Murder” will return for Season 4 on Sept. 28 at 10 p.m. EDT on ABC.
