I will never forgive you

There was a lot of interesting facts revealing in this episode! Miyuki is Yamanobe's sister; Tazaki cheated on her with Ryoko who is Yamanobe's fiancé and the she died; I am not even sure if Tazaki killed her, I think that she committed suicide because of what he did. Therefore, Yamanobe decided to lead revenge on Tazaki by making him get his memory back in pain.

Now, he will even make him "The Quiz Show" contestant to lead a psychological war against him. I understand why he is such a freaking sadist who enjoys other people's pain.
