Idk about her, really. She seems to lack the hunger for power that drives most Slytherins, but then again her determination to get revenge on Snow is kinda very Slytherin-y. And she's smart like a Ravenclaw, but I think her bravery and nerve are really underrated-- she's really very courageous and impulsive, much like a Gryffindor.

Honestly I can see her in all; mostly Ravenclaw or Slytherin. Gryffindor would also work due to all of the self-sacrificing. But I think she's very smart; she has to be in order to be the mayor, and be so right. But she's also got the Slytherin cleverness and ambition. So I really don't know with her. I just don't see her as a Puff.

Well she's been good for a long time, but she was also evil for a long time so probably not Slytherin or Gryffindor.

^ Slytherin is not necessarily the house of the "bad" people and Gryffindor is not where all the heroes go.
