The biggest mystery left in this show is the Duke's name. Even his own mother never says it
The Duke is such a good kid. Gerbera's hurt him so much, even if it wasn't on purpose, and yet he still cherishes the memories of his early childhood where she acted like a loving mother to him. She remembers as well and is nostalgic of that time. Hopefully she will get to ruffle his hair again once his curse is lifted.
Daleth was fantastic once again. She might just be the stand out character of this show for me.
