‘In The Dark’ Season 1 Finale Spoilers: Does Episode 13 Reveal Tyson’s Killer?

There’s only one Season 1 episode left of The CW’s “In The Dark” still to air, and, after last week’s episode, there are a lot of questions the finale needs to answer.

In episode 12, Dean (Rich Sommer) helped Murphy (Perry Mattfeld) celebrate her birthday, despite her not loving the occasion. He took her rollerskating, helped her reunite with Jess (Brooke Markham) and finally told her he had feelings for her, leading to the two of them sharing a kiss.

“Not the worst birthday after all,” Murphy told Dean afterward.

Unfortunately, this was the end of them celebrating the day together because he received a text and had to “run really quick for a work thing to help Jules [Saycon Sengbloh].”

Only, Jules didn’t need his help with anything because she was on her own solo mission, searching for the person working with Nia (Nicki Micheaux). She followed her to a meet-up in a parking garage, and while Jules couldn’t see exactly who Nia was meeting with, she did see the mystery person’s boots and the police-issued gun holster on their ankle.

This led to the episode ending with Dean returning home and the camera zooming in on his work boots and ankle gun holster. Is he working with Nia to frame Darnell (Keston John) for Tyson’s (Thamela Mpumlwana) murder? Is Dean the actual killer? Or is this all just a fake-out and the real dirty cop will be revealed in the Season 1 finale of “In The Dark” on Thursday?

According to the synopsis for Season 1, episode 13 (titled “It's Always Been You”), not only will Murphy finally discover the truth about what happened to her best friend, Tyson, but things also “begin to take an interesting turn between Murphy and Dean.”

What kind of “interesting turn”?

Well, the promo video shows them alone together in multiple scenes, and she’s looking a bit nervous and scared in each one of them. The final snippet of the trailer even sees Murphy attacking him while they’re driving together in his car.

Is it because she’s connected her own clues and thinks he’s Tyson’s killer? Did he do something completely different that upset her?

Find out when the Season 1 finale of “In The Dark,” written and directed by Corinne Kingsbury, airs on Thursday at 9 p.m. EDT.
