This is just showing how much Bennett hates Caroline. I know it is short but...

I was never fully able to forgive Caroline for what she did. She destroyed my life, my arm, and my trust. She deserved to pay. I knew exactly how now that she and Senator Perrin had arrived to my lab. She was an atrocity that needed to be put down. I wanted to make her pay for what she did. I would make her feel exactly what I had. I would give her a memory of mine so she would find out how this hurt. Even though my nerves were shot I could still feel my dead arm, I was constantly receiving phantom pains that reminded me exactly what Caroline had done to me, not just my arm but my life as well.

I decided to give her my memory of how my arm died, give her a glimpse of how evil Caroline truly is. Because she would be me in the memory, she would lose the use of her left arm. She deserved to suffer for what she did. She deserved worse than I could do right now but I would make her pay, if not today eventually.

The last part is kind of an idea of what made her choose Echo's offer of taking revenge on Caroline so soon. I may do another chapter of sorts with that.
