"There's a few of us here who remember what Kilgrave did in this precinct. I had nightmares of holding my own gun to my head. The feeling of my finger on the trigger." "I recommend hypnosis." "I didn't need that, because, uh, the dreams stopped the day you took that asshole out."
Eddy Costa was working at the office when Kilgrave took control of every one in it. He was forced to place his pistol next to his head, with his finger on the trigger. He sat this way until Kilgrave left, finally allowing him to put his pistol away. This encounter with Kilgrave gave him nightmares, which continued until the moment Jessica Jones murdered Kilgrave.
Murder of Robert Coleman
"Victim's name was Robert Coleman. Ever heard of him?" "He came to me. He wanted to hire me, but I was booked." "How shitty must you feel? Guy comes to you for help and winds up dead around the corner from you."
"Hey, listen, just in case you come up with anything else for us–" "One show-and-tell doesn't make us partners." "You want to go it alone, that's your call. But there's a lot of people on the force that wanna see you locked up." "And you're the only white hat in a sea of black hats." "Not the only one."
Eddy Costa was a wise and honorable man, as Jessica Jones considered the only "white hat in a sea of black hats." After being brainwashed by Kilgrave, he suffered from nightmares of losing his free will until Jones killed him. Afterward, Costa believed that Jessica was a good person, and believed that he owed a debt since she ridden the world of Kilgrave. Despite this, Costa was still lawful, as he and the police went on a hunt for Alisa Jones due to her killing his partner Ruth Sunday. Losing Sunday had a great effect on him, as he refused to listen to Jessica on the police going to kill her mother, stating that she killed "one of their own".
