Minerva McGonagall and Godric Gryffindor
Minerva McGonagall had been a Gryffindor from the moment that the sorting hat had touched her head, and she wasn't just one of those students who went to Gryffindor because there wasn't really any other house that she could be in, Minerva was a true Gryffindor. Hogwarts appealed to her like nothing else had, she simply loved it. On the day of her graduation, she knew that she had to come back. There wasn't anywhere in the world where she felt safer, or more at home. It was her home. So when she came back it was obvious to everyone there that she would become the head of Gryffindor house, and to no ones surprise she did. Then, when she saw every student go through the school and saw some of them become her lions she couldn't help but pass judgement. While she took pride in the truly great students, she couldn't sometimes help but wonder if Godric Gryffindor would be disappointed.
