"Would you like me to say The Knave every time I address you, or would Knave be acceptable?" It's a polite question but one that Charles takes seriously. He wants to make certain he addresses her correctly to her comfort level. It might seem more of a title to him than a name, but that's just from his world's point of view. He's well aware they are somewhere else entirely.

"My school is for people who develop supernatural abilities, which only happens at puberty." So the age bracket is for a very specific reason. Charles would ordinarily never speak so freely about his school or his students, but this is not a world that seems afraid of powered people, or would shy away from mutants. He feels almost like the strange is normal here.

"The lack of a generic education program in this city, or the children there to learn it, is horrifying to me personally, but that's how I am." He loves education. There is no formal education here.
