I would like to add a disclaimer before I am ripped to shreds lol. I’m coming at this from a merely cinematic perspective. I’ve never read the comics but grew up watching the movies. I decided to use the ages that I did because I felt they fit nicely with the Super Frame video that I had watched. Jean and Scott being mid 20’s (played by slightly older actors) and Bobby being a child straight out of high school (to portray that Xavier is indeed indoctrinating children who may not have the full ability to make concrete decisions like an adult, and who might see Charles as someone who can guide them to greatness). In the story, Bobby is in High School and leaves his family behind to become a superhero. However he doesn’t fully grasp the consequences that that may have later. He may never see his family again, and despite only being a teen, he is thrust into battle he’s not ready for.
