Control. Everything was always about control, and for once, he didn't seem to have any. A single comment from one of the other Slytherins was all it took for him to lose all semblance of belief in his hard won control. He had ran away, to terrified of the emotions that were rushing to the surface. He ran to the one place he knew it wouldn't matter if he lost control because no student would willingly go there, the Forbidden Forest. He ran and ran till he was so lost in the dark forest he might never find his way out, and his chest was constricting and he could barely breath, and he just let go, stopped trying to stay in control.
The second his control slipped away, it was like the flood gates had been open. He let out a cry of pain as he was suddenly overcome with magic that was so strange but oddly familiar. His heart let out a pang of loneliness as he fell to the ground. Suddenly he screamed in pain as something ripped free of the skin of his back, between his shoulder blades. As he finally let tears trail down his face he found himself falling into the welcome darkness of oblivion.
