Married At First Sight Chapter 4173 

Chapter 4173 

Kathryn sat there, looking as if she was ready to die, completely indifferent to their threats. Her calm defiance only fueled her brothers’ rage. 

Marco turned away, walking toward the car. He lifted the trunk and pulled it open. 

Inside, two sharp kitchen knives gleamed under the dim light. 

Sage hesitated before stepping forward, his voice unsteady. It was the first time he had ever been part of something like this—killing someone. And not just anyone, but his own sister. 

His hands trembled. “Big brother… are we really going to do this? Are we really going to kill her?” 

Marco grabbed one of the knives and shot Sage a cold glare. “What’s wrong? Are you backing out? Scared?” 

Sage stammered, “I… Brother, I’ve never killed anyone before. She’s our sister… I—I just don’t think I can do it.” 

Marco let out a sharp, disdainful laugh. “You still see her as family? She never saw us that way. Think about everything she’s done. Every move she made was a knife in our backs.” 

He shoved the knife toward Sage. “Here. Go on. You don’t have to kill her right away—just take a chunk out of her shoulder or arm. Let her suffer first. A quick death would be too easy for her. If I had the time, I’d make sure she begged for death before we were done.” 

Marco’s eyes burned with fury. “Sage, think about Mom. Think about Shiloh. Think about Dad. He’s crippled because of her. She knew Mom was coming back and didn’t warn Dad. She knew the wine was tampered with and kept quiet, letting the scheme succeed. Because of her, Shiloh and Dad were ruined.” 

Marco knew all too well why his mother had grown distant from his father—why she had been utterly heartbroken over Shiloh. It all led back to that scandal. 

And Shiloh… If she were still alive, Marco would have divorced his wife and married her. He would have given her the status she deserved. 

After all, they had grown up together. Before he learned they weren’t related by blood, he had already spoiled her beyond measure. And even after finding out the truth, nothing changed. 

When Shiloh had come to him, seducing him, he hadn’t resisted. 

No—it wasn’t incest. They weren’t siblings. There was nothing wrong with it. 

And Kathryn… She was the reason he had lost Shiloh.
