Be warned: there is NOTHING more dull than a writer running on about an idea. Unfortunately, you asked ;P. SO. With that said,

It was your piece about the grandfather who had lost his faith that got me thinking in this direction, though I wasn't expecting it to come out this way.

The play would be set in Poland, which means I'd probably have to figure out the proper title for the Nazi. I'm not sure if he would have been Gestapo or something else. It would be about this increasingly endangered convent that was holding a dangerous line, it being one of the miniscule number of places Jews could go for help. But only kids. And then this pregnant couple who nobody can bear to turn away. But they are problemmatic.

Because In addition to the obvious, it would be about the tensions between religions as the Catholic nuns who are literally saving the children also try to convert them. There would be older children in the group who understood what was happening and tried to rebel and a strict mother superior who had no intentions of letting them leave her care still Jewish. The kids would get sent to Sister Edmund for punishment. She would tell them they must mouth the words to fool the Germans. But then she would tell Mother Superior that she had convinced them their parents sent them to the orphanages for a reason and that they could best honor their that intention with trust and compliance. And then into this would come the pregnant couple, who would catalysts to the older children and a dangerous force of subversion in Mother Superior's strictly ordered world. And Sister Edmund, watching this conflict, would be increasingly conflicted herself. She would initially take the gun from the couple, but when she overheard Daniel telling Freda that he knew where it was hidden, she would come back and secretly move it. There would be a scene with the gun on the table and her talking about the weight to God, wondering if she should hide it somewhere else or just destroy it outright. Then the scene would shift to the sanctuary and a confrontation between the soldier and the couple, with Daniel taking some heroic risk to warn Mother Superior so she could take action to protect the kids. Freda and Daniel would try to pass themselves off as Catholics, but it wouldn't be working for some reason, and the soldier would be getting ready to shoot them, and the audience would know they are helpless in the climactic scene. And THEN Sister Edmund would step out and blow the Nazi away. The play would end there, with her getting ready to go after the partner. [this is probably what would save poor Aaron and give Ella a chance to take the body back over in this scenario above]

But the lights wouldn't come up. Instead, there would be a screen that showed scenes from the Holocaust, slowly at first, but with increasing speed. And then the images would suddenly stop on a screen that said "Never Again?" And the screen would go dark, but again, the lights wouldn't come up.

THEN there would be a flurry of images with names of countries (Country on the first screen, flood of genocide scenes in the next screens; next country and so on) and FINALLY another black screen asking "When is never?"

Then the audience could finally go home.
