S02E14 — Gavin MacInnis

After Mitchell Huston dies under mysterious circumstances at the Green Abbey hospice, Father Geddes points the finger at Dr. Sarah MacInnis. MacInnis ends up arrested, and Maz tells Ali he thinks they have an open and shut case, especially now that they also suspect Sarah of killing her husband Gavin (Mac) years earlier. Ross keeps trying to get Ali to move on the Seniuk case, and even though Tony learns that the real Nancy Seniuk was born in 1922 and died two years later, Ali lies to Ross when he asks her about it. She also suspects his motives after Malcolm, who sees them having dinner together, warns her against romance in the workplace.
