This is from a scene where Sonny is talking to Jason about Brenda's death. It occurred just prior to the yacht exploding on the 4 year anniversary of her death.
Sonny: I try not to, but gotta tell you something, I can't help but think of what she went through that night. Was there a moment where she realized she was going to die? I told you I'd die seeing Brenda's face. I just wonder if she died seeing mine.
