Hermione had finally stopped probing Harry as to how he knew what he was teaching them all and had instead fixated on wringing every single bit of knowledge he possessed out of him. He liked to think that they’d come to a silent agreement; he didn’t complain about her constant questions, and she didn’t ask him how he had all the answers. Occasionally, she’d swing her focus on Draco, who always responded with a dear-in-headlights look and deferred to Harry. This was somewhat damaging to their excuse that Draco had had private tutors and was the one who had actually taught Harry, but Draco hand waved it the one-time Hermione had brought it up.
