Eustace_Scrubb:
I suspect that _some_ Slytherins may leave Hogwarts.  But for this to
parallel the departure of Salazar from the other three founders,
wouldn't it mean that _all_ Slytherin students would have to leave and
indeed that Slytherin House would cease to exist?  I'm not sure I see
that happening.  Even if all current Slytherins left, there would
still be incoming students who might be sorted into the house, unless
the Sorting Hat refused to put anyone in Slytherin (or, depending on
one's understanding of what the Sorting Hat does, unless no incoming
students wanted to be sorted into Slytherin).

If there were to be a mass exodus of Slytherins, what effect might
that have on Snape? Would his position--whatever exactly it is--become
untenable? 

Cheers,
