Marguerite was thankful for her ability to adapt. It had been a skill she had learned early on, but it would definitely serve her well here. True, this was a situation beyond anything she could have imagined in France, even stranger than anything she might have performed on the stage. Religious Seals dragging people from all different times and places just showing up for no rhyme or reason beyond fighting in a war of good and evil? Cosmic good and evil at that, and not the evil of human nature and the injustice of inequality. Not that it really did any good when people became obsessed with the blood lust and became worse than the people they killed.
Still, how exactly was Marguerite supposed to respond to the fact that magic was real? That was just.. well, it was crazy. Or... she thought it was. But then Elphaba was speaking and suddenly she... was green. Okay. Green woman. In no discernible way that would say it was stage make up. Because.. no. Okay. Green. Weird. Magic. Weird. Very weird so silence it was. She wasn't going to die of shock. That would just be sad, to come away from the guillotine only to die from seeing a woman turn herself green.
Even so, she wasn't going to judge Elphaba on this. From the sounds of it, she had no real control of it. Well, she had the spell to not be green, but it seemed to be something she was born with. Really, it was sad that people would judge people on things they could not control. It always had been. If you had money, you were blessed, if not, it didn't matter if you were kind or good, it didn't matter if you had hatred in your heart. You were crushed and ignored. Until the poor had had enough and took matters into their own hands and judged people just for having money and being well off. And the cycle continued.
