Ben is whipping up breakfast for Susan Richards and her son Franklin when Starhawk beams onto their breakfast table. It seems that Vance Astro has gone down to earth with the intent of meeting his younger self, and Starhawk fears that this will create a time disaster. He's come to Ben and the FF for help, and then almost immediately departs to go contact the Avengers.
