Thankfully Draco had quick reflexes, although they weren't enough to prepare him for the solid weight of Jackson as he darted forward to catch him before he could slide all the way to the floor. He'd seen that flicker of consciousness regained, like waking from a dream—or a spell, a curse, some kind of possession—but he hadn't had time. At least Stupefy would have no lasting repercussions. And with how exhausted Jackson looked, it was tempting to let him sleep, take him up to the hospital wing and let him wake naturally.

But getting him there would only raise more questions, and while he did feel confident that the Headmistress was secure in her decision to appoint him, some of the words the possessing spirit had uttered had hit home.

He arranged Jackson, with a little difficulty, on the floor comfortably, and then touched his arm with his wand and whispered, "Ennervate." Better to deal with the yelling now.
