She scratched me so hard, you couldn't see, I was bleeding. And so you didn't really get see that detail. When I looked down at my arm and saw she had had really scratched me and I felt it all on my back, I just, you know, went over and slapped her back. It's not, like, my proudest moment but we were going through it.
