Harry did notice someone in the hall, but he figured it'd be the maid or someone of some sort of high importance to the Malfoy's. He had to think about going to school, Dumbledore would be able to sense his darkening thoughts, he was after all the wizard who helped him through out anything. The man he looked up to, had utter questioning now sorting through Harry's mind, surely if he'd a meeting with the sorting hat once more it may differ and he'd end up Slytherine.
"It'd be better if I had gone to school, Roshara." He spoke as honestly he could knowing it may alarm her, "the idea of too many people looking to blame someone for my disappearance is too overwhelming. I'd rather them blame me, over blaming you, or blaming anyone for that matter." Harry admitted, "I hope you understand."
