Fleshed Strategy
The Divine Doctor was not pleased by Rui's abstention, but Rui didn't care.
He had gotten the Divine Doctor to agree to participate in his plan. He had also gotten the Divine Doctor to agree to heal his father in return for his grandmother's prophecy.
He had managed to secure an agreement for both things that he cared for at the moment: Breaking out of the dungeon and getting his father healed.
Very rapidly, the tables turned as Rui held all the cards.
He was mixed about the Divine Doctor's commission. He was initially displeased at being referred to as a stethoscope, a tool. But when he rationally considered the Divine Doctor's offer, it wasn't particularly disagreeable.
He just didn't care to think about it at the moment.
He had far more important things to care about.
