Interesting start! Poor Snape though, once again being left to fend for himself after he fulfilled his purpose and without getting any recognition. This makes me wish Wizarding Britain will need his aid in some form in the future and he'll be able to laugh in their faces... Before leaving for the other end of the world, never looking back.

"He killed Dumbledore with an Unforgivable! There’s a reason they’re called that, you know."

Ah, yeees. As opposed to Unforgivables suddenly being "gallant" when St. Potter and his merry band of Gryffindors throw them around of course... Typical self-righteous Gryffindor-logic. And shame on Harry for apparently conveniently looking away when they decided Snape's fate.
