Peggy Rogers Gryffindor: G,S,H,R (order I'd rank the houses to match her)
Definite Gryffindor first and foremost, she did after all choose a profession where she gets to charge into battle and fight evil doers. She's brave, a little reckless no doubt, loves a good time and adventure, and really is an firecracker of a non-traditional white knight. I'd put Slytherin as her second ranked one, mostly because of how she handles the other side of the job, being very careful and clever with her public image, using whatever is at her disposal, and honestly that girl has a good ton of ambition. Hufflepuff third because yeah she's fiercely loyal to family, but her patience is limited unless it's part of a 'wait it out' plan. Dedication goes without saying but she's fickle unless she's really invested in it. Only things in Ravenclaw for her would be wit and individuality because really sometimes she takes independence too far.
