Not really. My brother and I do not have a good relationship, so if he even noticed me, he would run away. I do not think he would answer me if I tried to communicate either. So the only option is to chase him the moment I see him.

[After all, Hiiro thinks Rinne had run away partially because of how much trouble Hiiro had given him as children. There were other factors, but he couldn't easily imagine Rinne showing himself to him.]

As for the other thing... There was a pool I saw that made me see my father, but I was pulled back before I could enter it. It seems that these "illusions" are common here.
