He’d done so plenty of times in the handful of years he’d known her but never so much as this, and never on a topic that had her leaning into his space as she scribbled equations and weighed the benefits of regression versus difference-in-differences models with an enthusiasm that had his attention rapt on her. He barely understood the jargon but could follow the math well enough so felt that he wasn’t entirely wasting her time.
