Martha was a prodigy in battle. Whenever the fight starts, she just happens to know what to do and how to do it. That gave her the ability to fight and entrap enemies as she could somehow sense what would happen next in combat.
But she never really took the time to understand what it was and what the specifics were. She was just a prodigy fighting without thought. Her arrows were launched without any consideration as to why she needed to shoot at that specific angle.
She never took the time to think or explain to herself how she could win those many deadly encounters. But now she did. It was staring her right in the face, but she never really could voice it out.
What she never realized was that she could see the direction and turn off the battle. But now, it was more evident than ever. She finally understood the flow of the battle and the feeling of what would happen next.
