Niklaus' point of view
Isabella was right, I caused her death. Everything that happened to Kay Evans was because of me, the blame should be on me.
Where did everything begin to go wrong? After she spiked my drink? After Isabella's birth? After her craziness began? Or just all of the above?
Perhaps, if I had been told earlier that Kay and I would turn out that way, I would never believe it. We had gotten married with the hope that we would develop that love between us and inculcate it into our children.
Children? How funny, just a child we had together separated the marriage.
As everyone knew, after she had successfully drugged me, I forgave her eventually since she was my wife - I couldn't stay angry at her for long, anyway- but the damage had already been done.
