Prove to others? Or to herself? As disordered people who have schizoid traits get older, the cluster A traits start to dominate, and the B traits begin to soften. Likewise with cluster C traits in a cluster B personality. The c traits begin to take more charge. With the exception of severe borderline cases that is. I see more of the schizoid in TK, and if I'm right, that means she relies heavily on a rich fantasy world to get pleasure from life. Fantasy worlds may not seem like they have limits, but the reward that comes from playing out a certain fantasy over and again in the brain, without having it be fulfilled in real life, inevitably begins to dull.
I think that's where the alterations come into play. If the role playing gets dull and all your participants have begone to walk off the set... spice up the script and roll the dice again.
