Complete story — includes the ending
In flashback, Karen postpones going to college because she knows that her father and brother Kevin would not be able to run their family diner following her mother's death from cancer. She grows bored of her small-town life, and descends into using and selling drugs with her boyfriend Todd. One day, Kevin reveals to Karen that he has re-enrolled her in college, which Paxton celebrates with a family dinner, but this leads to an argument, and Karen runs off with Todd. After getting drunk and high together, they return to the travel trailer where Todd lives to find that Kevin is burning it down. Todd attacks Kevin, and Karen injures Todd with his own gun to stop him. She quickly drives Kevin away, but crashes, and Kevin dies. The local sheriff covers up Karen's involvement, and Paxton asks her to leave. In the present, Karen attends a service at Clinton Church when Dex, dressed as Daredevil, arrives and kills Lantom, intending to then kill Karen. Choosing between saving Karen and lying in wait for Fisk, Matt races to the church, where he confronts Dex, who badly beats Matt before Karen knocks Dex off a second-story balcony, after which he escapes.
