Is this more of the fear of being copied? Has the friend been validating to you? I would make sure I explain that this is a journey on about how folks got to be. It is a about pain perspective what that means the subjective experience, what were the manifestations, what is life like now rehabilitation what would have happened had this not happen re remembering, fine tuning ourselves. I think you have to make sure that alters involved aren't triggered to the point of invalidating plenty of folks sow their roll oaks or get into mid life crisis have lost their way lost their sense of identity. If you are triggered though you are triggered just be ready with a neat come back on why, what is all happening and if a good friend they will understand. I would possibly ask for a switch from an alter that has yet to understand and apparent normal I'm just along for the journey.

Yes, introject fictional characters can be their some of their life if they on television doing interviews depending on how they got here. If dead they once had life sometimes that is about asking inside what got you here was it a way of being on the movie and one liner depending on if a fragment etc.

Hopefully us as survivors are not out to get fictional characters on social media there is enough perspective to know this happens to some systems. They aren't out to get you all or seeking to control you unless you know someone famous meeting them in person.
