So I don't know if I'm retarded but I just thought about this.
I think all the grieving from Shifu about tribulations and all that is not about her, but about the Ye siblings. Probably one of them is fated to die, just like Shifu's sister did and she doesn't know how to avoid that.
So all that wasn't about traitors or her dying but about the sibling dying. Shiyuan's probably seeking power from the exaltists to avoid that.
What do you guys think?
