I admit a major fondness for the 'someone saves Snape' stories (in addition to him helping himself.
It hurts me that nobody tried to save him! Not the ones who went back in time to save the Hypogryff and Sirus (not from DEATH, from the Kiss.)
And not Lucius, although Lucius may have been preoccupied with finding his family. I still think the kids were callous. He'd never hurt them, only saved them and had just shown he had important information.
