Sure! Why not? What a cool idea to have someone as stunning as she is, and also as muscular and kick-ass, for this person to want to devote all their strength and love, more like a force of nature than a mere person, into giving to others in the missions? POWER NUN.

“Help me and you help the devil,” I whispered.
“So you told me,” she said.
…”What a lovely face you have. What is your name?“
“Gretchen.”
“You’re a nun, aren’t you, Gretchen?”
“How did you know that?”
“I could tell. Your hands, for one thing, the little silver wedding band, and something about your face, a radiance- the radiance of those who believe. And the fact that you stayed with me, Gretchen, when the others told you to go on. I know nuns when I see them. I’m the devil and when I behold goodness I know it… The devil needs you. The devil’s crying. He wants you to hold his hand. You’re not afraid of the devil, are you?”
“Not if he requires an act of mercy. Sleep now. They’re coming to give you another shot. I’m not leaving. Here, I’ll bring the chair to the side of the bed so you can hold my hand.”
