"The moment Sirius was sorted into Gryffindor, he became a different person. I mean– he was always different from me; crueller sometimes. Definitely more reckless. But being a Gryffindor allowed him a braveness he hadn’t yet had. Or maybe he'd always had it. Perhaps he'd just not yet known." That seemed more accurate. Sirius had not known. Had not understood the full capacity of his brave, brave heart. He was only a child, then. A helpless child.
