"You're so confident as to who she is, aren't you?" Null said, a hint of disdain in his voice. She was smart, smarter than he'd expected - but he was in this lie now, and he had to push forward. If he resolved this here and now, it would get buried under the weight of preparations for the coming conflict, and he wouldn't have to worry about it.
He felt himself pause a little when she showed him the scar; it was deep and wide, either made by a blunt knife or an animal's claw. From combat, definitely. Maybe he'd been wrong about this girl - maybe she was more like him than he'd expected. As though as an unspoken greeting, he unzipped the jacket of his leather armour, pulling it a little aside, showing her the beginnings of the massive scar down his torso - courtesy of a Deathclaw's talon.
He wished he could show her how much more he understood; after all, the physical was nothing compared to the pain that history could be responsible for. In a strange way, he still regretted that he hadn't a single scar to show from her; contemplated giving himself one, but figured that she wouldn't appreciate leaving that sort of mark. Everything he needed from her was inside his mind.
"I don't want him a factor either," Null said, voice softer now as he zipped his jacket back up. "I can take him out of the picture today, if you help me. But I can't do it alone."
