Finch finished eating breakfast, closed his notebook placed it in his inside breast pocket and rose from the chair.
He slowly left the great hall and mentally went over what classes he could sit in on. 

History of Magic might be good, he could actually provide insight in that class. Or perhaps DATDA or perhaps charms. Finch thought carefully for a few minutes. 

Finch set off towards the History of Magic classroom having decided that was as good a place as any to start.
