This is an alternate plausible possibility in the story of Severus Snape regarding how the events unfolded in the Shrieking Shack and the outcome of a single act of kindnesses to a broken hero. Twenty-two years of his life had been given over to following the desires of another; seventeen of them as Dumbledore's man, which meant he served two masters as a servant, spy and pawn.
