Kyle and Yost are among the better writers when it comes to having a grasp on Jean-Paul's character, and they prove it here in one page. From the fact that he would meet his death attempting to save a child, and be completely disgusted by the manner of his death instead of, y'know, being afraid or sad, to the fact that he only occasionally misses his sister, which is a key detail many get wrong. I feel like many writers want to write the Beaubier twins as though they were the Canadian Maximoffs: a pair of twins who are super close, despite the brother's overprotective and overbearing manner. While some of that is present in the Beaubier's relationship, they and the Maximoff twins are otherwise very different (penchant for super-speed aside).
I know many have their concerns about K&Y, but there are few writers I would rather have handling Jean-Paul*.
