The last time I used my powers, my real powers, the ones I was born with, was two years ago. Two years. Because apparently people don't like it when I do. Wolverine used my powers, though, to save my life. I was barely functional. But I would say its a case by case kind of a situation and hopefully at this point someone has beaten into me a moral compass. Otherwise I would just take what I want, when I wanted it, and go joy-riding in other people's powers.
And at what point do I give powers? What kind of power and to who? Have we met?
