“Well, I’m going to be perfectly honest. I didn’t know it was actually airing last night,” Costner admitted. Calling it a “swear-to-God moment,” the 69-year-old said, “I mean, I’ve been seeing ads with my face all over the place, and I’m thinking, ‘Gee, I’m not in that one.’ I’m not in this season.”

The Waterworld actor revealed how he did not know that Dutton's death was supposed to be part of Sunday's episode. “But I didn’t realize yesterday was the thing. Somebody said, ‘It played last night?’ And I said, ‘Hmm, okay.’ So no, I found out about it this morning actually,” Costner explained.

Dutton was found dead with a gunshot wound at the beginning of Episode 9. It was initially believed that he died by suicide, but later, it was revealed that he was murdered in a plot orchestrated by lawyer Sarah Atwood (Dawn Olivieri), who is sleeping with Jamie Dutton (Wes Bentley).

Admitting his feelings about Dutton's death, Costner said, “I didn’t see it. I heard it’s a suicide. That doesn’t make me wanna rush to go see it.” “They’re pretty smart people. Maybe it’s a red herring,” he went on, adding, “They’re very good. They’ll figure that out.”
