Sev gets turned

Halloween, 1976.One reckless decision.One “prank.”One life forever changed.Everyone remembers the incident beneath the Whomping Willow differently.According to Sirius Black, it was only meant to frighten Severus Snape.According to James Potter, he reached Severus before any real harm was done.According to Albus Dumbledore, silence is the only way to protect everyone involved.None of them know the full truth.James reaches Severus.Just not quickly enough.Remus Lupin, already transformed beneath the full moon, manages to sink his teeth into Severus before James drags him away. The attack lasts only seconds, but seconds are enough.Enough for blood to be spilled.Enough for ancient magic to awaken.Enough to change two lives instead of one.
