Well, there's no good way to say it, so here goes. Back in my world, at home, I killed a number of people in order to take their special abilities and use them for my own. It was something that my own special ability- intuitive aptitude- would push me to do, although there were other things going on with it, as well. I've stopped, but I do still have the aptitude.

I think Jemma wanted to be sure that other people were aware, people who could neutralize me if necessary. I thought it was a good idea, too.
