Did you really think Snape was involved in Godric Hollow?
I never started thinking that way until the interviewees kinda suggested it (in the new year interview with Jo.)
I'm still not convinced Snape was in love with Lily. I think Jo was suggesting that Snape had been loved by his mum rather than Lily but could be wrong.

Gotta say though, the idea of Snape being an eye-witness at Godric's Hollow is certainly growing.
Why else would he feel such life-shattering remorse?
Why else would he be so sensitative to being called a coward if he hadn't witnessed a horriable act that he was responsible for? This could be a response of a child brought up in domestic violence though... hmmm??... dunno

The 'stand aside silly girl' is a real puzzler
What do you think?
