Lily in Slytherin

[Steve Bates]

No: HPFGUIDX 1991

The more I think about this theory, the more I like it.  The green 
eyes and Voldemort saying he could have spared her fit, and the fact 
is, we still know next to nothing about Lily's personality.  We think 
of her defining characteristic as bravery because of the way she 
sacrificed her life for Harry, but maybe she had ambition, too, and 
that characteristic defined her more strongly.  Lily being in 
Slytherin also fits in with the theory of Snape being in love with 
her; on the other hand, I would suspect that most of the other 
Slytherins would have resented her, because she was Muggle born, 
while the majority of them would have come from old, pureblooded 
wizarding families.  If so, it would have made sense for her to seek 
out friends from other houses, which might have helped lead to her 
meeting and eventually falling in love with James.
