Colonel Nash is the father of Ellie Nash, and husband of Caroline Nash. He is a colonel in the Canadian Army. He was formerly part of a peacekeeping mission in Kabul. Because he left, Ellie became depressed, and turned to cutting. He is portrayed by Daniel Lévesque.
Season 3In Whisper to a Scream, he tells Ellie that he will be fine in Kabul, and reassures her that her mother's drinking is under control. He comforts her, and kisses his wife goodbye. He tells Ellie to always keep her smile. As he boards the bus, he waves goodbye to his family, who smile and wave back at him. He later calls Ellie and reveals that he arrived safely in Kabul. When he asks about her mother's condition, Ellie chooses to lie to him and says that she is doing fine, not revealing that she had become an alcoholic. His departure was part of the reason that Ellie's depression formed, which led to her begin cutting.
