Seriously though, she is not a hufflepuff. She may be kind, but she is not honest or hardworking. Nor is she brave. Nor is she All that intelligent (no offence)
She is however prone to cheating in tests, dreams of being famous and is desperately scared of becoming a no one.
This was my thinking precisely. *lol* And I kind of feel the same way about Hufflepuff... while I do think that Hufflepuff can sort of be a catch-all house because Helga Hufflepuff was a very generous, open-hearted person willing to take just about anyone; I also think that Hufflepuff has dominant traits that it values above all else... honesty, fairness, loyalty, and being hard-working. Sasha might fit the loyalty part, but not any of those dominant traits (and I disagree that EVERYONE can be like that... It's very difficult to be an honest, fair person... I think, maybe, it probably does show some optimism on the Sorting Hat's part, though, that anyone sorted in that house, even those who are part of the catch-alls, have the potential to be honest, fair, loyal, and hard-working).
Also, Jess... No offense taken. I am not any of my characters really, and I did intentionally make it so that she wasn't brave or particularly intelligent (or even hard-working... She is determined, but if she can find some way to get out of hard work to achieve her goals, she will). Anyway, I'm perfectly happy with making her a Transfiguration professor eventually, then (which is why I allowed for an either or thing; wanted to clarify with you, first)
Sorry, I didn't make her choice to be in Slytherin clear.... The thing is, Hufflepuff House does have a reputation for being the catch-all, ordinary, average House (even though, that isn't true; there are a lot of great Hufflepuffs), and that's the way Sasha thought. She thought if she got into Hufflepuff, it would mean she was average, ordinary... boring. She was really very adamant about not ending up in that House because she wanted to be someone great, a star, famous, influential! The Sorting Hat had thought about putting her in Hufflepuff originally, but it had a lot of doubts about that (and I think the only reason it was considering Hufflepuff was because it was taking her muggle-born status into account... while I do think the Sorting Hat judges someone more on who they are rather than what they are; I'm sure it is no doubt aware of many of the Slytherin's prejudices against muggleborns and wouldn't want to sort muggleborns into a house where they wouldn't be able to take harassment, prejudice, and ultimately end up failing because of it. The Sorting Hat seems to really want to put people in Houses where it knows people can succeed and reach their full potential. If she had been a pure-blood or half-blood, the Sorting Hat probably wouldn't have had ANY doubts) BECAUSE of the fact that she was dishonest, unfair, and not very hard-working.
There was also the fact that she was very ambitious... and also, as was previously stated, she's very proud of her Muggleborn status.... now, correct me if I'm wrong... But aren't Slytherins very proud of their pureblood status? And isn't that mainly the argument that's been used against her being in Slytherin? That she isn't proud enough of her heritage? And I think mostly it's because she's so ridiculously confident in who she is and who she wants to be (someone rich and famous) that the Sorting Hat thought that Slytherin would be the best House for her... because she'd be capable of persevering through the harassment and prejudice because of that confidence and because of her ambitious "whatever it takes to get what I want" mentality.
