Hermione was startled by his admission. Why would Ron care anything about where she was? They hadn't exactly been good friends for more than half their lives. Once they were off being trained by their respective Death Eater mentors, they never had much use for the other. Of course they would politely smile and conduct inane conversations whenever they were forced to occupy the same space, but they most certainly were not friends. Knowing that he would ask Draco Malfoy about her, of all the people in the world, was suspicious.
