After reading Lonesome's post, I wonder how my T's needs played into his decision to become a T. If I had to guess, I'd say maybe he was the rescuer type, likes the power that can come with the role, or a way to get intimacy needs fulfilled at a safe distance.
These are all my projections of course, as he doesn't show his needs and they don't get revealed indirectly through his patterns either. It's interesting to guess at, and sort of fun. Lrad, do you have ideas in mind if you were to take a guess?
