By some strange coincidence (I have ideas about this, but this is not the place to discuss them), we watched three things together that helped provide referrents for our second discussion.

One was an old episode of Star Trek Voyager where a bi-special character was split into two people, each a purified version of the two species. At first the two versions were at odds with one another but in the end they realized they needed each other.

The second thing we watched was a movie called Inside Out. My daughter and son-in-law wanted my granddaughter to watch it because she has been having issues with her emotional regulation (she is three). The movie presented emotions as characters who had alternating control of the person.

The third was the movie Split. (I will not discuss what I thought of the movie here.)

So I was able to refer to these in our conversation and they helped my daughter understand things better!

All in all, I am glad I have disclosed to the people I have chosen to. Scout assessed that the risks of not doing so were at least as bad as doing so. It has helped so far. But I will not be disclosing to people willy-nilly.
