In an interview with TV Insider, Goldberg defined the entire reasoning behind Sally’s meltdown, wherein she sees the police officer’s eye start to bleed and finally ends up turning round and going the opposite means:
“That is going to be some deep insider baseball, but it surely’s as a result of she’s seeing the man she killed. It is the identical actor. It is Anthony Molinari. So she goes and sees the cop, after which when she realizes that it is the man, she’s having a nervous breakdown basically. And when she sees his face, I feel she’s so confused and fearful that she’s halted in her tracks. I feel if he had stayed that maybe she would’ve come again, bounced again, and she or he would’ve turned herself in. Nevertheless it’s him. It is the concern of what she did.”
Within the season 3 finale, Sally killed Shane, a hitman who had been employed to kill Barry however unintentionally caught her in his crosshairs. She ended up beating Shane to dying with a baseball bat, unloading all of her rage on the varied males who had abused her onto him. It was her worst second, the fruits of her time with Barry, who led her towards violence. If there’s something Sally feels responsible about, it is taking a life — even when he most likely would have taken hers as an alternative. This is not the primary time she’s hallucinated Shane, both, as she noticed him on the aircraft trip again to Joplin in the beginning of season 4. He is a manifestation of all of her guilt, and never simply the guilt she has over killing him. Sally has given up nearly the whole lot that ever mattered to her, and it is taking its toll.
