Holstering a pistol Bullets For Dinner moves towards Raylin hiding behind his Shield. She is sweating profusely after a lucky shot. She can't actually follow The honoured movements. Once Bullets For Dinner knew she was the target. She shot right after Raylin looking pained as she was about to die.
Bullets For Dinner says, "How do I fight someone I can't see." She is used to being in the back and shooting from afar where young don't need to follow their enemies movements so closely.
Raylin says, "you have to look for her silhouette don't focus on any one part for now." He only learnt this in the dungeons recently. Most players try to focus on the weapon this narrowing of their vision makes it impossible for them to react to monsters who sometimes min-max their abilities. As a protector, he has had to fight enemies like these to pass the Trials.
