Roxy looked up when she heard a voice shouting from above. She couldn't make out the words the person was saying, but considering the girl was practically falling on her head Roxy could guess what the girl was trying tell her. Roxy calculated the rate of the girls fall to determine where she needed to move to be safe. Although she had little schooling Roxy was something of a math genius. Being able to calculate speed and distance helped her get her knives exactly where she wanted them to go. Roxy stepped out of the falling girls way drawing one of her knives just in case she needed it.
