In a recent interview withTHR, Dillon addresses the death of Laird’s character in theMayor of Kingstownseason 3 finale, confirming thatIris' drug overdose was not a suicide. According to the creator, this unfortunate ending for Iris is part of a larger attempt to not “pull any punches,” and to depict the harsh realities of life. Check out Dillon’s comment below:

“She didn’t take her life; it was an accidental overdose. You know, that’s part of the authenticity of the show and where I grew up. I had struggled with heroin early on in my life, and I’ve had a lot of friends who passed away from [that]; opioid addiction is a real thing.
“What Taylor [Sheridan] has taught me is to talk about what you know, and don’t pull any punches. And that’s what we did. Life is brutal and unfair, and we wanted to tell real stories. And we wanted to have an impact. And that is as real as it gets.
“But I will say, what Emma Laird did with that character was extraordinary, beyond the page for sure. When you saw that last sequence, like you said, it broke your heart. And that’s what we wanted it to do.
“She worked so very hard on the series, and she was asked to do really difficult things, and she brought it. She left everything on field. From the work she did in season one; it was just a fully developed character. And we are very grateful for her as a person and as an actor. For someone like you to say it broke your heart, we did our job.”
