Your correction doesn't follow what I said. Though I guess I wasn't lucid enough.there is nothing really erring about it
wood release is a KKG
if she has it then she has a KKG, she really doesn't need to be a senju though for it
anything could happen/be explained
as easy as pie
I stated, the notion is erring, meaning Kekkei-Genkai doesn't solely appear on a bloodline as there are examples of people from different bloodline, yet having a common Kekkei-Genkai. I didn't suggest it's not Kekkei-Genkai because she has it.
Also, she does at least needs to associated with the clan, perhaps as a relative.
