For the rest of the day, Severus was running circles in his head. He should not have allowed himself to get carried away. But what Pot... Harry had done could have been disastrous. Of course, it had kept Longbottom's cauldron from blowing up, since that idiot boy had left his concoction on the burner for too long but ... never mind. He had to find a way to get through tonight's detention. Then he could work on his insufficient occlumency shields. For decades, he had trained himself not to feel. It had served him well in Voldemort's service. The ability to stay detached had been necessary for his sanity. Now, in Harry's service, he was lost. And he did not know what to do about it. Emotions ... entirely unwanted pushed to the surface, and there seemed to be no way to get rid of them.
