I was very happy that everybody felt the same, and they just got to it. Having three years on the show felt right for me, and I think that the arc of the character with all the developments in the story was probably coming to its natural end, which was great. I didn’t know until closer to when we were shooting how it would actually happen but there’d been a few conversations during the summer as far as how the season would unfold, and then during the season there were more conversations about what might be good and what might be good for me. Richard Flood spoke to Deadline about his character’s exit, and his perhaps unexpectedly happy feelings upon learning he would be leaving Grey’s Anatomy. When he couldn’t convince Hunt to turn himself in, Hayes chose to leave his job and take his children back to Ireland, rather than risk getting in trouble for Hunt's actions.

Hayes was presented with a moral dilemma in the Season 18 winter premiere, when Owen Hunt - thinking he was going to die - admitted that he’d helped a terminal patient end his life, and needed Hayes’ help in doing the same for others. Because the character’s story arc came to a natural end, Flood said he was actually “very happy” with the way the exit came together. Cormac Hayes said his goodbyes and walked out the doors of Grey-Sloan Memorial Hospital for likely the last time during “Living in a House Divided.” It was announced during February's winter premiere that Richard Flood would be leaving Grey’s Anatomy after playing Hayes for three years on the ABC medical drama.
