Whispers

"Snape was definitely up to something. The signs were all there, but he had no evidence. He considered speaking to McGonagall about it, but it felt like his first year all over again. He knew that McGonagall trusted Snape, and without proof his suspicions would just be shot down." Written after the Final Battle, canon except Snape surviving and Epi. 3- to 5-shot. With a twist.
