Ts tend to be protective of their clients in the therapy space. Your friend should have told her T that she was going to bring you. But what is done is done. But that might help you understand her T's response. You did a good thing by going there for your friend. And after all, THAT is the relationship you were assisting in that now. Your friend will always remember that you were there for her when she needed you. And what could be more important than that?

About the CSA item, a huge part of CSA is minimalizing the events. Ts are trained to spot the unconscious things that upset us. So naturally a client may have no idea that the event has caused the subconscious impact it has caused.

The best thing to do is to be very frank with T about your perceptions. The reason is not to suggest T is wrong about things, but instead it will help T better understand your point of view at this time about the event. And that can tell a lot more information that just going along with whatever T happens to be saying about it. Even when we insist and feel that something does not matter, those very emotions are a big part of the equation.
