@Dwelt @Purplesky Many thanks for your advice!
I think what you said relates very much to our situation. I did ask the Young, and he replied, nobody needs to know. He asked me to keep it a secret from anyone. But I know the host would really like to know, that's why he sees the T. He wants to figure out what exactly happened to him, why they are in his head messing with his life (he's been fighting with them, mainly the Young, recently, because of some disturbing behaviors. But now I understand it might be caused by the Young trying to numb himself from all the memories. He couldn't help crying so much when those memories pass his mind. The host also told me sometimes he just suddenly starts crying and feels so dark and just wants to disappear, but he has no idea why. I guess it's like an emotional overflow from the Young).
At the same time, I feel so sad for the Young. He has such a heavy burden on him and endured so much for the host but all the host knows is how Young's messing with his life. He doesn't show any gratitude, which is understandable because he doesn't know, and he's blaming the Young all the time, which only makes things worse. I really want him to know that Young has done an incredible job protecting him and saving his life. And then maybe he can convince the Young that he's not a kid anymore, that he's strong and wise enough to slowly receive memories now. It would be so beneficial for building trust between them. But maybe this is gonna be the next, next step?
For now, Young is still heavily traumatized, so I guess it's safer to stabilize his situation first and then let him share memories with the host when he feels confident and comfortable enough to do so.
In summary, I will ask and discuss with the host in case Young shares memories with me what we should do. I will meet his T recently anyway, maybe I can mention that it'll be helpful talking with the young, suggest him to guide the session in that direction. And if I get another chance to talk with Young, I will share with him how I see the host now as a wise grownup man. I hope that sounds reasonable and safe enough?
Again, million thanks!!! I'm really happy and grateful to have found this community
