Again, people see what they want to see. As to the marriage, AFAIK, everything is great. I've heard nothing about any rift between Damien and Lorri, much to the chagrin of the nons! Believe me, if there were trouble in the marriage, it would be all over Facebook and Twitter and who knows where else? They might even re-institute The Hoax to report that. The strain on their marriage from all of the public pressure must be enormous.
There's been too much of that kind of thing in this case already, like with Exhibit 500. "Ooh, Damien had problems as a teen. He must be a murderer." That's crazy logic, just as it would be crazy to assume that, should the marriage fail, it would be because Damien killed Christopher, Michael and Stevie. It simply doesn't follow.
