Alex is the first to feel the effects of the wave.
There you all are at graduation. It's a beautiful outdoor ceremony, and you are all taking in the fresh May air. Alex gets called up on stage and gets his diploma, even being recognized for honors.
As he exits the stage, you notice him walking a little funny. He makes it to the sidewalk, and you notice that he is now wearing heels! His whole body shrinks down as breasts and hips emerge from beneath his robe. Long brown hair frames her new feminine face as she lets out a giggle. She seems more amused than anything.
