Sunne ( Clementine ) was originally going to be Estella's biological sibling, Estella was also going to have a 'love interest that her mother would try to force her to be with, because he was "such a nice guy". But he was scrapped because I felt like a love triangle wouldn't be that interesting.

Estella was originally going to be a magician! she would have been more like Leon in personality. Estella was still going to be adopted but she would go over to the orphanage and help the kid's there!
It was also planned for her to help children and people without homes by letting them stay with her and her mother but that was scrapped because it conflicted with Pip and her backstory with her mother and I didn't want to add tooo much to Estella's backstory already because it was already pretty excessive
