House of M #2, p.9

Cincinnati, Ohio in the classroom of Ms. Katherine (Kitty) Pryde (a.k.a. ShadowCat), doing what we have all come to know her at her best: as a teacher. Love the smudged chalky image of the classroom and the teacher chicken-scratch handwriting on blackboard.

Ms.Pryde: Okay, let's get into it.
Who was the FIRST Mutant?
AND DON'T SAY MOSES OR JESUS. I'm talking officially.
Who was the first mutant?

A single hand goes up from a little mutant girl, a few rows back: Uh...was it Prince Namor?

Ms. Pryde: That's, Yes-- That's right. Did you read the chapter already?

little mutant girl: No, Miss Pryde, my-- my mom has a kind of fixation with him.

Ms. Pryde: Okay, Namor IS considered the first mutant...
...Let's talk about some of the things he said during World War II and how they relate to where we are today...
