How do Ellie and Jeremiah first meet?

Ellie and Jeremiah are both new to Percy. Ellie, looking at her class schedule and trying to find her classroom, bumps into Jeremiah, sending her textbooks crashing onto the floor. As the two apologize and bend to pick up the books, they begin laughing. Jeremiah introduces himself, but Ellie does not give her name, entranced by his voice and good looks. As the two walk away in separate directions, they both catch each other's eye again.
