The fact that Ben has no one to back him up, no Grandpa Max to help him become a stronger superhero and figure out his powers worries her. Especially with people like Slade out there.

"Do you have a pen?" She can't let this kid out there alone like this. Sure, Lucky Girl is alone, but she's got karate and years of experience behind her. She has the internet and her brains to keep her out of trouble. Ben seems like the type of person who would take candy from a stranger if they said it was safe; and that worries her. He's a good guy and will probably make a great superhero with the right guidance.
