Leave Mertz to Rosary

You hated to give Rosary the short end of the stick here, facing her up against an opponent who clearly had the worst in mind for her, but you needed the aid of your other saintess to fight Nil Riiche. Rosary would have to handle Mertz herself.

"Oh. Yes. Erm... Are you... one-hundred percent sure about that?" Rosary questioned one more time, clutching her cross close to her breast as her knees practically knocked together beneath her habit. "I don't actually carry a weapon, you know..."

You reminded Rosary she didn't have to defeat Mertz. You just needed her to keep him occupied until Nil was taken care of.

"I-I'll do my best!"

"And I'll do my worst," Mertz promised, grinning from ear to ear as he approached. Instead of going to him, Rosary backed away, past the wine casket where you all had been hiding. "Oh, poor sister. You could have been part of our new regime, if you'd only attended the church gathering like a good little choir girl. Now, you're about to become a prisoner of my guards." He spread his arms from side to side. "We won't harm a pretty curl on your head. Perhaps you'll even get out of jail early... for good behavior, heh heh."

"Oh, Geod protect me..." the nun prayed, summoning up a glowing barrier around herself for the sake of protection. "I-If you try to swing that sword at me... You will only break it!"

"We'll see what breaks first," the guard captain sneered, beginning his charge. You'd have to leave Rosary to it, as much as you wanted to step in and help.
