Something I’ve never noticed before:
Snape not only deflects McGonagall’s attack but uses it to take down Alecto and Amycus in a single armwave behind his visual field. Like they both had their wands out too but BOY they did not see that coming. Snape knew that he needed to get rid of them before being driven out of the castle so that they wouldn’t harm any of the students GOD what a badass motherfucker
thank you, that hurt.
I like that idea, but I ascribe to the belief that McGonagall’s attack hit them as well. I think he was deflecting and they didn’t deflect in time. Snape’s a badass, but so is McGonagall. People tend to forget that because she’s not so much a target of fandom lust.
