"There's a guy?" Jake smirked at her, resisting the urge to tease her about this random guy who wasn't a friend but helped her out. "I don't know, Lois, someone who helps someone else out sounds pretty friendly to me. What's his name?"

Jake just wanted to know because he was curious. And because he would absolutely run a background check on this kid to make sure he wasn't some horrible criminal when he wasn't helping young girls with their school work.
