If you are asking me to forgive for what your brother did.... I honestly don't think that you are reason for that. He hates mother right since the start because she is council founder. If we think in another way around you actually protected mother to your uttermost extent. So, there is no need to ask for the forgiveness. I think you already know me very well dad…. I never judge people by who they are, or where they are from…. I only care how they are…" Jean said.
Julian already know this very well and he already expected this outcome. It is only that he is very worried if his daughter changed in these five years.
