Severus Snape was shaking with fear and rage. The Dark Lord had just said whom he would be going to kill. Lily and her family.
Seeing a small box on the ground, while waiting for Albus Dumbledore, he picked it up. Opening the lid, he heard,
My mother said there’s only one way
Sweet angel boy narrow and straight
Time it has passed teachings they fade
Now her angel boy has gone astray
I’ve held the hand of the devil
felt his breath on my skin
Dip me into the water wash me again
Can I still be forgiven for all of
Or have I gone to far now
have I lost my wings
He had already thought to warn Lily, but now he knew he needed to make amends. He would spy or do whatever Dumbledore asked him to do.
