"Didn't know about it until recently." He said with a shrug, "Few months ago, like I said, cropped up as a life or death thing." He shrugged again, more a roll of his shoulders, trying to work the tension out of his spine and off the back of his neck, he remembered that from when he'd escaped Alastair with Needy, how his back had been stiff for days, "Kind of how it happened the second time too, so, I'm going to learn how to control it when I'm actually thinking clearly."
Because that whole series of escapades while he was cracked out on Kryptonite didn't count, mostly because it was the Auphe half of him that had been doing it, so of course he'd know how to control something that came as easy as breathing, "And why the roof?" He shrugged, "Needed someplace out of the way in case it didn't work, or in case it worked too well."
