I disagree there Xena. If I'm comatose for 10 years, I've abandoned my wife and family, even if it's not of my own free will. To pretend that while lying comatose in a hospital bed that I was any kind of a husband or father would be a whopper of a lie. If I'm ever reduced to that state, I hope my wife moves on her, for her sake.
Michael should have moved on as well, divorced Terri and move on and let Terri be loved and cared for by her parents.
