Cassandra was cursed

I think a lot of people (myself included) thought that Mark S. would meet Gemma/ Ms.Casey and have some sort of innate fondness or love for her that would transcend severance and they’d escape together. But Mark S IS NOT Mark Scout. How many times can they tell us that!  He is a separate person! But I kept thinking of them as the same in some way. My mom is actually upset because she thinks Mark and Helly's relationship is worth less than Mark and Gemma's, which is kind of the whole point right? Why is their relationship worth less? Because they aren't real people? Who gets to say what a real person is!!!

This ending is really damning of Lumon (and of US!) because they really did create entirely separate consciousness. And to dismiss them as "innies" and not real people is flawed. They are separate people with autonomy and feelings and goals. People who are murdered at a moment’s notice by themselves and expected to go along with it! 

To be Her would mean being wiped clean of all of your past, your obligations, responsibilities, family. But you can’t start over with a clean slate if you are the slate, so you pretend and it’s working, for a little while.
