I think, when meeting Minthara, I really miss the opportunity to honestly tell her what happened to us, that I really am not a True Soul, but at the same time say, "Don't rush to kill me, I really want to help you, because I liked you - and we'll figure all the rest later when you are convinced what can you trust me". I think her attitude towards us when she finds out that we are helping her of own free will and not by the will of the absolute should be better. And also she will obviously give us more information about the Absolute.
Perhaps she won't believe us if we say that she also has a tadpole. But he will remember this.
That is, I want to directly say "I liked you, so I will help you and I'll be honest with you, that's the only reason" - I will not be mistaken if I say that this is what most players who helped her would like to say.
