"Which is a long time, I hope," he admitted. She was correct to think he knew Xavier's faults, he did, though perhaps not so well as she did. Still, it was in spite of these that he returned to the mansion and the X-Men when Professor X asked him to. He did not have to believe in the man to believe in what he was trying to do. His school was a good thing, a 'haven for mutants' just like Genosha was, only without the despotic criminal leader (though Kurt expected this woman might disagree with that assessment of Xavier). For Kurt the school and it's students came first and his X-Men family. He'd spent time away and he'd never been as happy or fulfilled as he was with the X-Men, trying to make a real difference for mutants in the world.
