My god this was a beautiful story. I actually had trouble following the plot the first time I listened—just not in the right frame of mind to give the story the concentration it needed, I guess—but even so I thoroughly enjoyed listening to it; even when I didn't understand what was going on, the language was so lyrical, so poetic, that I just loved listening to it. And Amal's comments about the story at the end of the episode were really helpful in understanding what was happening in the story that helped me follow it a bit better on my second listening.
And I am so glad I listened a second time! The plot of the story is so lovely, and powerful, and I loved all three sections of the story, the failed magic spell and then the two counterfactuals about Stevie and Lucy's lives without the spell. I loved the uncertainty about which story was what "really" happened, and the way the raven and the fox persisted throughout the counterfactual stories; even in the timelines where the spell was not actually cast, the recurrence of the raven and the fox lent a bit of a magical realist element.
