... the first break was a crack that ran right down the middle, through my mind and line of concentration.
By the time Mirror came around, it was healing. Crooked, brokenly. So she had to rebreak it--think like resetting a broken bone. Only it broke differently, along the lines of memories you could say.
She moved things around, and while doing so, the memories of "Jinx" shattered and fell apart. So she put them back together, in different places, positions. And it's been like that since then.
It's why I say people can call me either Kaito or Jinx. And have them pick. They both me, but.
