dinosaurs,
Good to see you posting.
Identifying what can trigger a certain alter to pop out when they do is tough. It takes a lot of paying attention to details and sifting through old, dusty puzzle pieces. Investigative work for sure.
Maybe you need to ask your angry part why they are the one always out in T? What is it that makes
them come out for T? Are they protecting all the rest by pushing T away?
Maybe if the angry one can say what needs to be said, it will free up some time for your helper.
