....so Shirabishi Rin had made company-playing and go along with a girl (Shinmiyouji Rei) almost same age as her real sister (Shirabishi Kyouka)... yet Rin "bullied" Kyouka...
So my guess is that he doesn´t believe his father is the LL killer at all so when a new body was found he though the real culprit came back and started checking things out, he probably thought it was Kyouka's father and that is why he was in contact with him at one point.
Is it just me or this chapter had already been done uploaded to MD before? I feel like I have read this days ago.
Nah, the first couple of page is pretty similar to the previous chapter so I got confused for a moment.
