In the two-minute clip, Deb finds her brother Dexter with his hands on the knife that he just plunged into Travis in the church.
Dexter: "I came to do one last forensics sweep like you asked me to do. Travis was here. He came at me with his sword. I fought him off. I knocked him out."
Deb: "How did he end up wrapped with plastic on the alter?"
Dexter: "I snapped."
See what else happens in the clip in the video below. "Dexter" returns Sundays at 9 p.m. ET/PT starting Sept. 30.
