Trigger warning: This article mentions sexual assault, gun violence, and other sensitive topics.
We have passed the halfway point of The Good Daughter, and more of the dots are beginning to connect. A flashback revealed what caused Sam and Charlie's relationship to sour, while Sam also learned a game-changing revelation about Kelly in the courtroom: She's pregnant. For now, it's a secret, but it's going to be the kind of secret that blows this case wide open.
The Good Daughter episode 4 opens with a flashback to Rusty and Charlie awaiting Sam's return from the hospital. Rusty explains that Sam suffered from a traumatic brain injury and she might not be like herself right away. Charlie goes into the kitchen to grab a pack of cigarettes from Rusty's jacket pocket and she finds a tooth underneath the oven. She returns and sees her dad crying.
Back in real time, Charlie and Rusty talk over the case since Rusty's taking it over again. Before she leaves town, Sam wants to tell Ava that Kelly's pregnant. She tells her dad the Sam apologized to her, but when she mentions Gamma, Rusty changes the mood by tapping his pen on the rim of a mug, just like he did in the past. On her way out of the hospital, Charlie flirts with Ben.
Sam works on her case notes while considering whether she should say goodbye to Kelly before she leaves town. While talking to Lenore about the potential fathers of Kelly's baby, Charlie arrives at the office and counts out Huck. She also fills Sam in on Huck's theory about the shot order. They run through theories, disagreeing and not landing on one option.

Sam finds Kelly's yearbook and questions Huck
In the car, Sam tries to talk to Charlie about her life, and when she brings up her pregnancy all those years ago, Charlie lies and says that it was a false alarm. Charlie also ignores Sam's question about Ben. Sam talks to Ava and reveals the pregnancy. She's surprised, but Ava reveals that Kelly previously had an abortion when she was 14. Ava doesn't know who the father could be.
Ava brings Sam to Kelly's "hiding hole" outside, where she had be sleeping more and more. Sam finds a yearbook from three years ago and other things that the police hadn't found. On her way out, Eli rushes toward Sam and threatens her from representing Kelly. Charlie exits her car with a bat to defend Sam, who slyly hands Charlie the yearbook. The Culpeppers join the fun to run them out.
After leaving, they pull over and look through the yearbook, which is full of bullying messages from her fellow students. There's also a horrible message from Colton Alexander, the brother of Emma, the girl who died. They realize that the prosecutor could weave a story of Kelly getting revenge on Colton. Sam tells Charlie to stop talking to Huck, but she wants to meet with him this time.
Sam meets Huck at the bar and shows him Colton's message in Kelly's yearbook. He pushes back against Sam when she brings up his sister, but she keeps asking him about Kelly. Huck isn't particularly helpful when Sam continues peppering him with questions. He insists that he was trying to help Kelly by hiding the gun. Meanwhile, Charlie confronts a kid about his yearbook message.
Little Mike offers Charlie some insights into Kelly's life at school and details about how she reacted to people. Sam recorded her conversation with Huck, but she didn't get much of substance. Charlie drops by Jaxon's house to ask him about what happened to Kelly in ninth grade. Colton Alexander got her drunk and let the whole football team have sex with her, resulting in her pregnancy.
Jaxon also tells Charlie that Huck came into Mrs. Pinkman's class to yell at her, but she shut him down. Rusty asks Sam to bring a picture of Gamma from his desk to the hospital. She sits at his crowded desk to search for the photo, which she eventually finds. She also finds a letter to M. Pointer from Zach Culpepper that simply reads, "YOU OWE ME."

Rusty leaves Sam and Charlie to find their way back to each other
Sam remembers receiving a letter from Charlie that called for an end to their relationship. She was in denial since she believed that she and Charlie always made up from their fights. She expected Charlie to call her, but she apparently never heard from her. In real time, the sisters talk about Sam learning that Huck claimed not to know much about Colton Alexander.
Charlie also shares what she learned from her juvie clients, and Sam expresses that she's proud of how good her sister is at her job. Sam abruptly reveals that she was married, but Anton died of cancer six months ago. She placed her ring in his urn, and she wears his ring to keep him with her. Charlie sits and listens to Sam tell her about Anton, also giving her a chance to apologize to her.
Instead of taking the opportunity to open up to Sam, Charlie ends the conversation and tells Sam her car is ready. Sam pleads with Charlie to be honest with her, but she doesn't make any inroads, just Charlie even madder. Sam meets with Rusty at the hospital on her way out of town and asks about the letter, but she doesn't share anything. Again, Rusty won't tell Sam what's going on with Charlie.
Ben joins Charlie at home, and she fights for them to fix their marriage. She kisses him, but he turns her down and leaves. Back at the hospital, Sam learns that Rusty was secretly at her first criminal trial. She gives him the photo of Gamma, and he explains another photo taken on their first date. He asks Sam to take Charlie to get the picture at the farmhouse and bring her back for more stories. She agrees to stay one more night. Coming back outside from getting Rusty water, she finds him dead.
