In the previous episode, Laurel and Wes flew to Ohio to look into his mother's case file, where she discovered that Wes may have killed his mother. Executive producer Pete Nowalk told Entertainment Weekly: "Wes has always appeared to be the show's puppy, but he's clearly shown he's not so innocent. So maybe being a killer has always been in his DNA. We all suppress childhood memories, especially the more traumatic ones."

A new promo for the episode opens with Wes saying, "I remember standing over her, holding the knife." Laurel asks Ananlise, "Did Wes kill his mother?" Then the scene flashes back to Rose's dead body as we see Annalise running away from the crime scene. "The mystery of his mother's death will be solved", declares the voice-over.
