From what I have been coming to understand more and more the system and the communication within the system, is of paramount importance. I (actually parts) don't like working on communication between each other and would rather focus on the familiar patterns that come naturally to us when discussing the very hard personal experiences we went through.

I too wonder why a trauma T would not be more familiar with dissociation. That's something I would want to know for sure!

Also one T at a time. If I am talking to two I tend to want to play one against the other. That's just my system though.
I hope it was ok to put in my two cents.
