An X-Men Fanfic Something strange was going on with Logan. No, that wasn’t quite right. Something was always going on with Logan, but this time it was more concerning than usual. He had requested some time off from teaching (a sick day, he called it, though he never got sick), and the professor, for some reason known only to himself, agreed without comment. Even stranger, Hank had cheerfully offered to cover those classes until Logan was feeling better and invited Logan to sit in on them, in case he “needed a refresher”.
