Okay so I mentioned how Sasha doesn't fall somehow? I think I figured it out. See, Sasha did two nearly unforgivable acts, and the second should have definitely caused her to fall. Like, staging a coup and imprisoning both your best friends? Fall worth for sure. Heck, even she was surprised, having expecting this to happen. But the sashanne is too strong lol. Of course, that's only part of it, because the marcanne is also strong. Anne knows Sasha is not a great friend, but she can't pin all the blame on her, she won't. She believes Grime encouraged her to be even worse, that Grime is pressuring her to do these things, so Sasha doesn't fall.
Marcy does. Why's that, you might say? Because now Anne knows that Andrias manipulated her, of course, so shouldn't she hold that same sliver of forgiveness that she holds for Sasha? But she doesn't. Because Andrias had nothing to do with lying to them about the box, nothing to do with dragging her away from her family, her life. That was all Marcy. So all the blame falls onto her shoulders, covering her with darkness, a shadow that will never leave.
