Question: Was Logan's healing factor completely removed by Viper or just slowed down a lot? In the funeral fight scenes and on the train he was shot and stabbed multiple times, yet he was only slowed down. It seems if the healing factor was at 0% he would have bled to death right after. (Especially after a shotgun blast to the abdomen at point blank range) And is the healing factor back at 100% now even after the grandfather sucked a bunch of it out?
Question: Approximately what year is the film set? The adamantium would place it after the Origins film (which I believe to be set circa 1979) in which he loses most if not all of his memories. This begs the question, how is it that he remembers WWII and the atomic bomb?
