To the point that very little mattered outside of solutions, or possible solutions to their current problem. Turning to her, he listened to her words.

"What does that mean, exactly?" As he asked, he opened his palm again to stare down at the line she had pointed at. "You have never seen it before, but do you know what it could mean?" As he asked, his brow furrowed again, but for an entirely different reason. "You realize this body is a vessel, yes? You are not reading my palm, but the man that gave up his body so that I may be able to be here."
