We Need To Talk About Snape

On the 20th anniversary of the Battle of Hogwarts, the magical community is up in arms at a Ministry decision to give a posthumous Order Of Merlin to Severus Snape. Prof Binns assigns a special assignment to Albus, Rose and Scorpius to give their opinion on the late double agent. A fic for both Snape lovers and haters. Mostly canon, though characters slightly OOC. One shot.
