Harry’s thoughts were very interesting to read. It was good to see that he recognized he had a problem, even if he didn’t know how to handle it. That requires maturity, no matter what Kingsley said. Also, Harry’s thoughts about his childhood, his relatives, Snape and Dumbledore were level-headed, like here: At least he knew by now that his family was no more normal than he was, or Snape either. For most people, such traps and torments just didn’t exist, and never would, which was something he was able to be grateful for.
This was great: His tongue had much the same edge, but he wasn't using it to slash permanently bleeding wounds; more like paper-cuts, too shallow to sting beyond the moment.
Another one of my favourites: In mid-afternoon, Harry had recommended him, at top volume, to fuck a manticore and to eat the resulting offspring for breakfast, before he had turned his back on him and walked away to rest his head against the back wall of the room, shaking, sweating, and praying incoherently for some lightning strike to annihilate his tormentor.
I liked Snape’s unorthodox methods of teaching self-control and the cosiness afterwards.
