Faustus gave his father a long look then sighed and nodded. "Okay," he said reluctantly. He hated how the students seemed to get more of his Dad's attention than he did. He understood that his Dad had an important job but wasn't he important too?
He brightened when Harry suggested doing something else then grinned. "I've explored a bit, mostly here in the dungeons. I was being methodical, starting here then going up. Mum always liked being methodical." His grinned widened momentarily at Harry's wink then he looked sceptical and slightly challenging. "Dad seems to know everything about the castle. I haven't surprised him once with anything I've found down here."
He shot a quick look over at his father, who was looking both smugly amused and, when he looked at Harry, slightly arch, then turned back to Harry.
