Sirius wanted Regulus to be sorted into Gryffindor and pines over it. Disclaimer - I don't own Harry Potter. This was written for the Froday Amnesty for March 2022, but the prompt I picked was 11.16 which was hope. And the story didn't end up the way I wanted, as originally it was supposed to be a tie in to the Worst Witch crossover I've written already only for it to end up being way to much fluff on Sirius part which didn't quite fit with what was going on with Regulus in the story. Oh well. Perhaps another time.
