A special ability to predict my opponent's moves. That doesn't begin to describe it. Time... ran together. The future... blending into the moment.

No substitute for knowing.
I'll never take another life. Not even hers. So I'll pretend to go all out... and then I'll die. I don't have to do this. I can still study Batman's method. I can be good enough for the costume. I can be... mediocre. For a lifetime. Or perfect. For a year.
