It helps, as well, that Sirius has spoken to his Healer about properly moving forward into Healer training, and has spent much of his excess energy contacting both Minerva and Dumbledore in order to get the qualifications and letters of recommendation necessary to enrol in a course. (Having been incarcerated, even if only briefly, and having no formal healing experience, Sirius will need quite a bit of help to be admitted; thankfully, he has friends in high places, and Healer Jones agreed to write a letter himself, assuring Sirius’ own mental health.)
