The Christinas
The Christinas is a label for the group of body-splits and is a specific subset of people in our head who are not always grouped into the same subsystem. There are some people we are positive are Christinas, and there are some whom we're uncertain, or in spite of knowing they probably should be, it doesn't feel right to say that they are. It's very confusing.
However, the Christinas tend to be younger than the external-origin folks, with a few exceptions on either side.
