It's against Harry's best judgment to let Malfoy go unscathed. But that's an easy thing to deal with later, comparatively. He'll have to contact the Headmaster, and Draco will likely need to be brought in. They can't have students sneaking out of Hogwarts at all hours, and certainly not to be...doing what Harry had seen him doing with James.

Looking at James, it's impossible not to see that the kid is terrified. And he should be. Harry hadn't expected this, and he has no idea how to deal with it. This is the kind of thing Ginny would excel at, but Harry is one hundred percent sure it's not his place to tell her. If there's even anything to tell. James hadn't answered him about how long this had been going on. Maybe it was a one-time thing. Maybe Harry's getting worked up for nothing.

"And you?" he asks, folding his arms. "What am I supposed to do with you?"
