I liked this too, but I still don’t get why her shoe was left there.
I’m just assuming she left it there for him to find? Because earlier he’d told her about how “her story” is supposed to go, and that she leaves the shoe and that’s how her Prince finds her, and she laughed it off as being silly. So when she went to wait for him, and then someone came to abduct her or whatever, she remembered what he’d said and dropped the shoe as a “sign” for him to find when he got there.
That makes perfect sense. Thank you, that’s been bugging me.
