zgirnius:
I happen to remember part of the question...here you go!

> World Book Day Chat, 2004:
> Kyla: What made Sirius decide to send Snape to the Willow?
> JK Rowling replies -> Because Sirius loathed Snape (and the feeling 
was entirely mutual). You'll find out more about this in due course.

zgirnius:
And I agree with wynnleaf that this is ambiguous. We may be learning 
more about the 'prank' or more about the feelings of loathing between 
Sirius and Snape (or both).
