There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
I just remember the Sideliner's explanation which seems very good: by securing their territory, the brother allow Hipscar to perhaps recover his health and vigor. Hipscar is alone, thus he doesn't interfere with his brothers by being not a burden for them as Tshokwane says. Although this behaviour is able to be hard for some sensitive souls, it is clearly the best available option.
