T.B. gazed at the hot plate, turning over her second sandwich to brown, and didn't appear to hear the question. But the buzzing acquired a quality like... like the sound of glass shards crunching as they are stepped upon by a boot. It was rough and jagged, but entirely muffled, inward. It happened, and then it passed.
"I know what you're doing," he said quietly, still watching the hot plate. His voice was calm and inexpressive, though still his usual deep, rich rumble. "And while I approve of the exercise, bear in mind I'll be returning the favor, and I expect as much disclosure on your part as I give on mine."
He looked at her then, eyes sharp and watchful. "My family isn't the important thing. To know about my family, you need to know about my history; that will tell you all you need to know about my family, just in how I grew up. I was born as anyone is, and my young life was as normal as anyones. Well, not quite so normal; my family was wealthy, so I got to go to excellent early schools, up in the sun. I was the oldest of three children, and very physical , I was always strong and fast, and so I excelled in sports, and didn't care about academics in the least, as is common for young boys. I was popular, and handsome, and kissed my first girl before I was double digits old."
"Needless to say, puberty was not kind. At an age where boys find hair sprouting in uncomfortable places, I found hair sprouting literally everywhere. My mouth changed, my eyes changed, and my body..." he paused, his eyes unfocusing a bit as he looked inward with his mind's eye, "...my body changed, in all sorts of ways. Within a few months, I was like this."
The buzz of him had begun somewhat placidly, and gotten more jangly and minor key at the same time as he talked about his transformation. When he paused to remember something specific, there was an abrupt jab, like a stab, inward to the heart of the buzzing. But then it passed, and he looked directly at her again.
"Naturally, my parents took me to the best doctors they could afford. They tried gene therapy, but the DNA was too pervasive. They joined support groups, and signed me up for support groups. I sat next to kids with an extra eyelid, and kids who got flashes of the next few seconds, looking like I do now, and I thought, 'what can they possibly help me with?' When my parents started to get threats, when our apartment door was vandalized, when someone went so far as to travel all the way down to the street level to get some rocks just to throw at me and my family," and here the anger or irritation, if that's what it was, returned, and his words got a touch forceful, "I knew I was causing them more harm the longer I stayed. Nothing they could do was helping me, either. So... I got out. I ran away."
"I got help from some of the people I'd met, so I suppose the support groups had some positive ends, just not the ones they had intended. Eventually I migrated to the surface. The only people who were really family anymore were those like me; not furry and violent, but freaks. It doesn't matter what it is you can do; if you're different, you're hunted. It's us against them, and the stakes are life and death. So you need all the family you can get; you don't get to choose your relations, but you're supposed to stand by them, and they're supposed to stand by you." His buzz had taken on a different tone, one strong and forceful, but still somehow harmonious.
He cocked his monobrow at her. "So you want to know about my family? In a very real sense, you are my family. You and others like us. They're the only family I can rely on, at any rate, and then only sometimes." He flipped the cooked sandwich over onto her plate with expert aim. "Did that give you the data you wanted to know?"
