Turtle Heart

Wikipedia:
Turtle Heart is a wandering glassblower from Quadling country. He comes upon Melena's home while Frex is out preaching. Melena and Turtle Heart have an extended affair, and it is suggested that Frex may have had intimate relations with him, as well. It is also strongly suggested that he is the father of Nessarose.

Me:
I want to go beyond the book with Turtle Heart. He is such a great character, and he really embodies the dysfunction rampant in Elphaba's family during her childhood. I don't want to just suggest that Turtle Heart is Nessarose's father, but I want to SUGGEST that he is her father. I want to show the affair with Melena AND Frexspar. I want to even go as far as to show that Turtle Heart was the only one who really showed any love towards Elphaba, and then link the glass he gave her to that in the end of the movie. His death needs to be traumatic for the audience; at least enough to explain why both Frex and Melena just shut down after he dies.
I like the parallels I've heard drawn between his death and the way that Nessa later allows Munchkinland to operate with animal and human sacrifices.

This may not be possible because most of the movie will need to be focused on how the three witches interact with each other, and if too much time is spent on Elphaba and Nessa’s childhoods, then there won’t be any time left for that.
