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.
So... Considering how Mandevu and Ncila coincidentally joined the kill after the Mbiri males left, perhaps they're avoiding their rivals instead of trying to chase them off? They had chased Shaka off a giraffe kill once, but 2 Mbiris togethet may be too much for them.
Still 2 prime brothers like them can't afford not to go deal with 2 invaders, normally lions either accept the challenge or go nomadic, though I doubt the Mbiri males have any real interest in taking over, for them Manyeleti is probably their backyard, similar to how the PCM sees Londolozi in SS.
